ArCut end mills are equipped with a double rake face chip flute form, having a smaller than normal contact zone. This accelerates the chip during formation, resulting in a short curled chip, improving chip evacuation and surface quality. Due to the short curled chips, machining corners is drastically improved as chip packing is avoided. ArCut end mills are also a preferred choice when highly accurate machined straight walls are required.

Features

  • Center cutting
  • One tool for roughing and finishing operations
  • Slotting depths up to 1 x D
  • Double rake design to manage chip formation

Niagara Cutter C230R-0.250-D3-R030.0-Z2 C230R Carbide Radius End Mill, TiAlN Finish, 2 Flutes, 1/4" Cutting Diameter, 1/4" Shank Diameter, 2-1/2" Overall Length, 3/4"

Model: N91173   |    Mpn: C230R-0.250-D3-R030.0-Z2   |    PartNumber: C230R-0.250-D3-R030.0-Z2   |   Asin: B00RV54OAO

The Niagara Cutter C230R TiAlN-coated carbide corner radius end mill has two flutes and a 30-degree helix angle for general-purpose machining on a range of materials. Corner radius end mills have a square end with rounded corners on the cutting edges to reduce chipping and extend the life of the tool. The two flutes have better chip-carrying capacity than end mills with more flutes while offering additional support when the tool goes deep into the material in applications with a high depth of cut. The 30-degree helix angle supports general-purpose applications. It balances lower angles strong cutting edge for difficult-to-machine materials with higher angles increased cutting action. The TiAlN coating resists heat better than TiN and TiCN coatings, increasing tool life and performance. It also offers increased hardness for abrasion resistance and may reduce the need for lubricants based on the application. (TiAlN is suitable for a range of materials, but TiCN or uncoated end mills are recommended for machining aluminum.) The carbide substrate is harder than high-speed or cobalt steel, making it more wear resistant at high speeds and providing longer tool life. The center-cutting design has cutting teeth at the end of the tool, so it can be fed into the workpiece like a drill bit. Cutting diameter tolerance is +0.000 to -0.002 . The round shank accommodates a variety of holders. End mills are designed to remove material and create multi-dimensional shapes and profiles. They have cutting edges along the outside diameter and flutes that remove chips from the cutting area and allow cooling fluids to enter. If heat is not reduced effectively, the tool s cutting edges will dull and additional material buildup can occur. The number of flutes can range from two to eight. Two-flute designs offer the most efficient chip removal, but more flutes provide a smoother finish. The shank is the end of the tool held in place by a tool holder or machine.

Features

  • Two flutes offer better chip-carrying capacity than end mills with more flutes, enhancing the tool's ability to remove material
  • Corner radius end mills have cutting edges with rounded corners to reduce chipping and provide longer tool life
  • Titanium aluminum nitride (TiAlN) coating lubricates the end mill for high-temperature stability and abrasion resistance at high cutting speeds
  • Carbide can run at higher speeds than high-speed steel, resisting abrasion and high cutting temperatures
  • Center-cutting design allows the end mill to plunge into material like a drill bit while also performing conventional surface milling

SGS 36701 Z1PCR Z-Carb-AP High Performance End Mill, Titanium Nitride-X Coating with Flat, 3/8" Cutting Diameter, 7/8" Cutting Length, 3/8" Shank Diameter, 2-1/2" Length, 0.010" Corner Radius

Model: SGS 36701   |    Mpn: 36701   |    Ean: 0691781367019   |    PartNumber: 36701   |   Asin: B00O7UBWOM

The Z-Carb-AP offers performance so advanced, it goes way beyond typical high performance carbide end mills. With most 4-flute end mills, the cutting teeth enter and exit the material creating a natural rhythm that results in damaging harmonics. The harmonics produce a frequency that resonates through the entire end mill, resulting in chatter. With its patented, one of a kind geometry, the Z-Carb-AP offers three stages of chatter suppression.

Features

  • Superior chatter suppression through advanced patented design
  • Increase productivity by cutting deeper and wider without harmful harmonics
  • Lower cutting forces for dramatically longer tool life
  • With Patented Variable Rake

Niagara Cutter N61822 Carbide Corner Radius End Mill, Inch, TiAlN Finish, Finishing Cut, 35 Degree Helix, 3 Flutes, 2.5" Overall Length, 0.500" Cutting Diameter, 0.500" Shank Diameter, 0.030" Corner Radius

Model: N61822   |    Mpn: S335-0.500-D1-R030.3-Z3   |    Ean: 0698036618223   |    PartNumber: S335-0.500-D1-R030.3-Z3   |   Asin: B003AZZVWO

The Niagara Cutter S335 TiAlN-coated carbide corner radius end mill has three flutes, a 35-degree helix angle, and cutting edges with rounded corners for high-performance cuts on stainless steel, titanium, and high-temperature alloys. Corner radius on cutting edges reduces chipping and extends tool life. The 35-degree helix angle provides more support behind the cutting edge than higher angles, and increases cutting action and chip evacuation compared to lower helix angles. It efficiently cuts difficult-to-machine material such as stainless steel and titanium, moving it up the spiral and away from the workpiece. The end mill s three flutes provide better chip-carrying capacity than four flutes and a finer finish than two. They remove excess material from the cutting area and provide a third cutting edge to create an improved finish that may eliminate the need for a second finishing cut in some applications. This tool is best suited for slotting.

The TiAlN coating resists heat better than TiN and TiCN coatings, increasing tool life and performance. It also offers increased hardness compared to TiN and may reduce the need for lubricants based on the application. The carbide substrate is harder than high-speed or cobalt steel, making it more wear resistant at high speeds and providing longer tool life. The center-cutting design has cutting teeth at the end of the tool, so it can be fed straight into the workpiece like a drill bit. Cutting diameter tolerance is +0.000" to -0.002". The round shank accommodates a range of tool holders.

End mills are designed to remove material and create multi-dimensional shapes and profiles. They have cutting edges along the outside diameter and flutes that remove chips from the cutting area and allow cooling fluids to enter. If heat is not reduced effectively, the tool s cutting edges will dull and additional material buildup can occur. The number of flutes can range from two to eight. Two-flute designs offer the most efficient chip removal, but more flutes provide a smoother finish. The shank is the end of the tool held in place by a tool holder or machine. Center-cutting end mills can create three-dimensional shapes and profiles, and make plunge cuts similar to a drill bit. Non-center-cutting end mills are for applications such as peripheral milling and finishing, but cannot make plunge cuts.

Niagara Cutter has been designing and manufacturing precision cutting tools since 1954. Specializing in end mills, cutting mills, and saws, the company is based in New York and manufactures its tools at facilities in Pennsylvania and Massachusetts. This allows the company control over production, from substrate to coating, which is essential for customers in a variety of industries, especially aerospace and automotive.

Model: G85016   |    Mpn: G85016   |    PartNumber: G85016   |   Asin: B0080D9YA6

Solid carbide tools offer long tool life and faster cutting speeds than other substrates, but are more brittle and must be used with rigid toolholding systems. Titanium aluminum nitride coatings become self-lubricating when used at very high speeds, making them ideal for cutting without coolant ("dry machining"). Round shanks allow use with a wide variety of toolholding systems . When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging. High performance.

Niagara Cutter N61827 Carbide Corner Radius End Mill, Inch, TiAlN Finish, Finishing Cut, 35 Degree Helix, 3 Flutes, 4" Overall Length, 0.750" Cutting Diameter, 0.750" Shank Diameter, 0.030" Corner Radius

Model: N61827   |    Mpn: S335-0.750-D2-R030.3-Z3   |    Ean: 0698036618278   |    PartNumber: S335-0.750-D2-R030.3-Z3   |   Asin: B003AZZVYM

The Niagara Cutter S335 TiAlN-coated carbide corner radius end mill has three flutes, a 35-degree helix angle, and cutting edges with rounded corners for high-performance cuts on stainless steel, titanium, and high-temperature alloys. Corner radius on cutting edges reduces chipping and extends tool life. The 35-degree helix angle provides more support behind the cutting edge than higher angles, and increases cutting action and chip evacuation compared to lower helix angles. It efficiently cuts difficult-to-machine material such as stainless steel and titanium, moving it up the spiral and away from the workpiece. The end mill s three flutes provide better chip-carrying capacity than four flutes and a finer finish than two. They remove excess material from the cutting area and provide a third cutting edge to create an improved finish that may eliminate the need for a second finishing cut in some applications. This tool is best suited for slotting.

The TiAlN coating resists heat better than TiN and TiCN coatings, increasing tool life and performance. It also offers increased hardness compared to TiN and may reduce the need for lubricants based on the application. The carbide substrate is harder than high-speed or cobalt steel, making it more wear resistant at high speeds and providing longer tool life. The center-cutting design has cutting teeth at the end of the tool, so it can be fed straight into the workpiece like a drill bit. Cutting diameter tolerance is +0.000" to -0.002". The round shank accommodates a range of tool holders.

End mills are designed to remove material and create multi-dimensional shapes and profiles. They have cutting edges along the outside diameter and flutes that remove chips from the cutting area and allow cooling fluids to enter. If heat is not reduced effectively, the tool s cutting edges will dull and additional material buildup can occur. The number of flutes can range from two to eight. Two-flute designs offer the most efficient chip removal, but more flutes provide a smoother finish. The shank is the end of the tool held in place by a tool holder or machine. Center-cutting end mills can create three-dimensional shapes and profiles, and make plunge cuts similar to a drill bit. Non-center-cutting end mills are for applications such as peripheral milling and finishing, but cannot make plunge cuts.

Niagara Cutter has been designing and manufacturing precision cutting tools since 1954. Specializing in end mills, cutting mills, and saws, the company is based in New York and manufactures its tools at facilities in Pennsylvania and Massachusetts. This allows the company control over production, from substrate to coating, which is essential for customers in a variety of industries, especially aerospace and automotive.

Features

  • Corner radius end mills have cutting edges with rounded corners to reduce chipping and provide longer tool life
  • 35-degree helix angle provides increased cutting action and chip evacuation compared to lower helix angles for machining stainless steel and titanium
  • Three flutes provide better chip-carrying capacity than four flutes and a finer finish than two, reducing the need for a second finishing cut in some applications
  • Titanium aluminum nitride (TiAlN) coating lubricates the end mill for high-temperature stability and abrasion resistance at high cutting speeds, offering better heat resistance than TiN and TiCN coatings
  • Carbide can run at higher speeds than high-speed or cobalt steel, resisting wear and high cutting temperatures

Niagara Cutter N57890 Carbide Corner Radius End Mill, Long Reach, Uncoated Bright Finish, Roughing/Finishing Cut, 40-Degree, 3-Flute, 4" OAL, 0.375" Cut Diameter, 0.375" Shank Diameter, 0.015" Radius

Model: N57890   |    Mpn: AN340-0.375-E3-R015.0-Z3   |    Ean: 0698036578909   |    PartNumber: AN340-0.375-E3-R015.0-Z3   |   Asin: B003D7LPNI

The Niagara Cutter AN340 uncoated (bright) carbide corner radius end mill with extended-reach neck style has three flutes, a 40-degree helix angle, a wiper flat, and cutting edges with rounded corners for high-performance cuts on aluminum and other nonferrous materials where tool reach is a problem. Corner radius on cutting edges reduces chipping and extends tool life. The extended-reach neck style provides greater access to recessed areas of the workpiece than tools with a standard neck style. The 40-degree helix provides increased cutting action and chip evacuation compared to end mills with lower helix angles and more cutting edge strength than higher angles. It moves excess material quickly up the spiral and away from the workpiece. The end mill s three flutes provide better chip-carrying capacity than four flutes and a finer finish than two. They efficiently remove excess material from the cutting area and provide a third cutting edge to create an improved finish that may eliminate the need for a second finishing cut in some applications. A wiper flat on the cutting edges provides a smoother finish to the workpiece than conventional end mills. The rounded area behind the cutting edge, called the cylindrical land, minimizes tool vibration when machining nonferrous materials.

The carbide substrate is harder than high-speed or cobalt steel, making it more wear resistant at high speeds and providing longer tool life; this tool has no coating or surface treatment. The center-cutting design has cutting teeth at the end of the tool, so it can be fed straight into the workpiece like a drill bit. The tool has an eccentric primary relief feature that provides better support behind the cutting edge than a flat relief, reducing tooth breakage in deep cuts. Cutting diameter tolerance is +0.000" to -0.002". The round shank accommodates a range of tool holders.

End mills are designed to remove material and create multi-dimensional shapes and profiles. They have cutting edges along the outside diameter and flutes that remove chips from the cutting area and allow cooling fluids to enter.
