Union Butterfield 1585NR(UNC) High-Speed Steel Spiral Point Tap, Non-Relieved Style, Uncoated (Bright) Finish, Round Shank With Square End, Plug Chamfer, 3 Flute, H5 Tolerance, 3/8"-16 Thread Size

Model: 1012844   |    Mpn: 1585NR3/8X16H53FLNO2   |    Ean: 0698464023422   |    PartNumber: 1585NR3/8X16H53FLNO2   |   Asin: B003JY69NQ

The Union Butterfield 1585NR(UNC)/1585NR(UNF) uncoated, high-speed steel spiral point tap has a non-relieved design, straight flutes, and a round shank with a square end, and is used to create right-hand threads in a range of materials. It is available in two different ANSI thread specification standards: UNC (Unified Coarse) and UNF (Unified Fine). The spiral point of this tap (sometimes referred to as a gun tap ) pushes chips ahead of the tool and the straight flutes reduce clogging. Both characteristics make it suitable for threading through holes (extending through the workpiece). The non-relieved design of this series has concentric threads without pitch diameter relief. It is recommended for applications requiring close gauging fits and in older equipment that is not sufficiently rigid to accomodate the relieved-style series of spiral pointed taps.

Right-hand threads are designed to tighten when a head or nut is rotated clockwise (the most common threading direction). High-speed steel (HSS) is a common general-purpose steel for cutting tools, and is compatible with a variety of materials. With no coating or surface treatment, this uncoated tool can be used on a broad range of materials and provide an economical alternative to coated tools. The round shank with square end helps to minimize rotation in the tool holder. This tool can be used in machines, such as drill presses or lathes, or with hand tools such as tap wrenches.

In the Union Butterfield 1585NR(UNC) and 1585NR(UNF) tap series, taps with 1/4 to 5/16 nominal diameters are available with two or three flutes, and those with 3/8 to 3/4 nominal diameters all have three flutes. The 1585NR(UNC) taps are available with a variety of chamfers; 1585NR(UNF) taps all have plug chamfers. This tap conforms to ANSI standards and can create threads to a depth 2 times its diameter. It is suitable for ANSI 2B and 3B tolerance classes: 2B is an average quality fit for commercial and industrial fasteners; 3B produces close-tolerance fasteners used for greater resistance to stripping, as in aerospace applications.

Taps produce internal threads in previously formed holes and can be used in machines (such as drill presses) or with hand tools. Common types of taps include hand taps, spiral point taps, spiral flute taps, thread forming taps, and pipe taps. Hand taps (straight-flute taps) collect chips in the straight flutes of the tool; spiral point taps push chips through holes ahead of the tool; and spiral flute taps pull chips back from the tip of the tool, up and out the hole. Thread forming taps, also known as cold forming taps, press rather than cut to create threads in a drilled hole, and no chips are created. Pipe taps create threads in pipes and pipe fittings. Each thread type designates a thread profile and each type is identified with an abbreviation. In the U.S. and Canada, the Unified Thread Standard is the dominant thread type, including UNC (Unified Coarse), UNF (Unified Fine), and NPT (National Pipe Taper) threads, among others.

Union Butterfield TN1534(UNC) High-Speed Steel Spiral Point Tap, Relieved Style, TiN Coated, Round Shank With Square End, Plug Chamfer, 4-40 Thread Size

Model: 1060805   |    Mpn: TN15344-40   |    Ean: 0698464004582   |    PartNumber: TN15344-40   |   Asin: B003JY75WK

The Union Butterfield TN1534(UNC)/TN1534(UNF) high-speed steel spiral point tap has a relieved-style design, straight flutes, a titanium nitride (TiN) coating, and a round shank with a square end, and is used to create right-hand threads in a range of materials. It is available in two different ANSI thread specification standards: UNC (Unified Coarse) and UNF (Unified Fine). The spiral point of this tap (sometimes referred to as a gun tap ) pushes chips ahead of the tool and the straight flutes reduce clogging. Both characteristics make it suitable for threading through holes (extending through the workpiece). Titanium nitride (TiN) is a gold-colored ceramic coating that combines hardness with low friction for extended cutting tool life and permits faster cutting speeds than with uncoated tools. Relieved-style tap design reduces friction between the tap and workpiece for reduced tool wear. This tap features eccentric, full pitch diameter thread relief for free cutting and increased tool life. The plug chamfer distributes cutting to ease tapping at the beginning of the hole and to maintain correct perpendicular alignment with the workpiece.

Right-hand threads are designed to tighten when a head or nut is rotated clockwise (the most common threading direction). High-speed steel (HSS) is a common general-purpose steel for cutting tools, and is compatible with a variety of materials.

Dormer E005M4 Spiral Point Taps, Bright Coating, M4, Metric Coarse, Full Length 2.1/8", Flute Length 0.2484", Shank Diameter 0.1680"

Model: 0580301   |    Mpn: E005M4   |    Ean: 7320760580301   |    PartNumber: E005M4   |   Asin: B003JY6I0A

The Dormer MTT-X E005/MTT-X E015 powdered-metal steel spiral point tap has a round shank with a square end, gold oxide finish, and a plug chamfer, and is used to create metric right-hand threads in a range of materials, with best performance in steel, copper, brass, aluminum, magnesium, and thermoplastics. It is available in two different thread specification standards: Metric Coarse (M) or Metric Fine (MF). The spiral point of this tap (sometimes referred to as a gun tap ) pushes chips ahead of the tool and the straight flutes reduce clogging. Both characteristics make it suitable for threading through holes (extending through the workpiece). Gold oxide is a low-temperature heat treatment that reduces grinding stress within the tool. The plug chamfer distributes cutting to ease tapping at the beginning of the hole and to maintain correct perpendicular alignment with the workpiece.

Right-hand threads are designed to tighten when a head or nut is rotated clockwise (the most common threading direction). Powdered-metal steel offers performance that approaches that of solid carbide tools but with the toughness and shock-resistance of high-speed steel. The round shank with square end helps to minimize rotation in the tool holder. This tool can be used in machines, such as drill presses or lathes, or with hand tools such as tap wrenches.

In the Dormer MTT-X E005 series, taps with nominal diameters of 4 mm to 12 mm are available with two or three flutes and taps with nominal diameters of 14 mm to 20 mm have three flutes. In the MTT-X E015 series, all taps have three flutes. All taps in both series have plug chamfers. This tap conforms to ANSI standards and can create threads to a depth two-and-a-half times its diameter. It is suitable for the 6H tolerance class: 6H is used for a normal length of thread engagement and medium tolerance quality.

Taps produce internal threads in previously formed holes and can be used in machines (such as drill presses) or with hand tools. Common types of taps include hand taps, spiral point taps, spiral flute taps, thread forming taps, and pipe taps. Hand taps (straight-flute taps) collect chips in the straight flutes of the tool; spiral point taps push chips through holes ahead of the tool; and spiral flute taps pull chips back from the tip of the tool, up and out the hole.

Dormer E001 Powdered Metal Spiral Point Threading Tap, Black Oxide Finish, Round Shank With Square End, Plug Chamfer, M3-0.50 Thread Size

Model: 0567722   |    Mpn: E001M3   |    Ean: 7320760567722   |    PartNumber: E001M3   |   Asin: B003JY6HAG

The Dormer MTT-X E001/MTT-X E011 powdered-metal steel spiral point tap has a round shank with a square end, black oxide finish, and a plug chamfer, and is used to create metric right-hand threads in a number of materials, with best performance in steel. It is available in two different thread specification standards: Metric Coarse (M) or Metric Fine (MF). The spiral point of this tap (sometimes referred to as a gun tap ) pushes chips ahead of the tool and the straight flutes reduce clogging. Both characteristics make it suitable for threading through holes (extending through the workpiece). The black oxide finish improves lubricity, resists corrosion, and will not chip or flake. It also helps to prevent buildup and welding of material on the tap s cutting edge when working with iron and steel. The plug chamfer distributes cutting to ease tapping at the beginning of the hole and to maintain correct perpendicular alignment with the workpiece.

Right-hand threads are designed to tighten when a head or nut is rotated clockwise (the most common threading direction). Powdered-metal steel offers performance that approaches that of solid carbide tools but with the toughness and shock-resistance of high-speed steel. The round shank with square end helps to minimize rotation in the tool holder. This tool can be used in machines, such as drill presses or lathes, or with hand tools such as tap wrenches.

In the Dormer MTT-X E001 series, taps with nominal diameters of 3 mm to 16 mm have three flutes and taps with nominal diameters of 18 mm to 24 mm have four flutes. In the MTT-X E011 series, taps with nominal diameters of 4 mm to 16 mm have three flutes and taps with nominal diameters of 18 mm to 24 mm have four flutes. All taps in both series have plug chamfers. This tap conforms to ISO 529 standards and can create threads to a depth two-and-a-half times its diameter. It is suitable for the 6H tolerance class: 6H is used for a normal length of thread engagement and medium tolerance quality.

Taps produce internal threads in previously formed holes and can be used in machines (such as drill presses) or with hand tools. Common types of taps include hand taps, spiral point taps, spiral flute taps, thread forming taps, and pipe taps. Hand taps (straight-flute taps) collect chips in the straight flutes of the tool; spiral point taps push chips through holes ahead of the tool; and spiral flute taps pull chips back from the tip of the tool, up and out the hole. Thread forming taps, also known as cold forming taps, press rather than cut to create threads in a drilled hole, and no chips are created. Pipe taps create threads in pipes and pipe fittings. Each thread type designates a thread profile and each type is identified with an abbreviation. In the U.S. and Canada, the Unified Thread Standard is the dominant thread type, including UNC (Unified Coarse), UNF (Unified Fine), and NPT (National Pipe Taper) threads, among others.

Dormer Pramet manufactures cutting tools under the following brands: Precision Twist Drill, Dormer, Union Butterfield and Pramet. The company has locations around the world, and provides tools adhering to ANSI, NAS, and DIN standards.

Features

  • Spiral point and straight flutes for cutting threads in through holes
  • Spiral point pushes chips ahead of tool to reduce clogging
  • Powdered-metal steel for performance approaching that of solid carbide tools, with the toughness and shock-resistance of high-speed steel
  • Black oxide finish improves lubricity, resists corrosion, and helps prevent buildup
  • Plug chamfer for easier starting and correct perpendicular alignment
