Dormer E011 Powdered Metal Spiral Point Threading Tap, Black Oxide Finish, Round Shank With Square End, Plug Chamfer, M18-1.50 Thread Size

Model: 0568552   |    Mpn: E011M18X1.5   |    Ean: 7320760568552   |    PartNumber: E011M18X1.5   |   Asin: B003JY6JJ0

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.

Union Butterfield 1534NR(UNF) High-Speed Steel Spiral Point Tap, Uncoated (Bright) Finish, Round Shank With Square End, Plug Chamfer, H1 Tolerance, 10-32 Thread Size

Model: 1010843   |    Mpn: 1534NR10-32H1NO2   |    Ean: 0698464019647   |    PartNumber: 1534NR10-32H1NO2   |   Asin: B003JY629W

The Union Butterfield 1534NR(UNC)/1534(UNF)/1534(UNS) 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 three different ANSI thread specification standards: UNC (Unified Coarse), UNF (Unified Fine), or UNS (Unified Special). 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 the 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 1534NR tap series all taps have two flutes. The 1534NR(UNC) and 1534(UNF) taps are available with a variety of chamfers. The single 1534(UNS) tap has a plug chamfer. This tap conforms to ANSI standards and can create threads to a depth 2 times its diameter. Both 1534NR(UNC) and 1534NR(UNF) taps are 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. The single 1534NR(UNS) tap is suitable for the ANSI 3B tolerance class.

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 1785M High-Speed Steel Spiral Point Tap, Relieved Style, Uncoated (Bright) Finish, Round Shank With Square End, Plug Chamfer, M2.5-0.45 Thread Size

Model: 1012662   |    Mpn: 1785M2.5   |    Ean: 0698464036835   |    PartNumber: 1785M2.5   |   Asin: B003JY6GVQ

The Union Butterfield 1785M uncoated, high-speed steel spiral point tap has a relieved-style design, straight flutes with a plug chamfer, and a round shank with a square end, and is used to create right-hand threads in a range of materials. This tool produces ANSI standard threads in metric sizes. 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). Relieved-style tap design reduces the friction between tap and workpiece for reduced tool wear. A 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 the 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 1785M tap series, taps with nominal diameters of 2 mm to 8 mm have two flutes and those with diameters of 9 mm to 18 mm have three flutes. All taps in this series have plug chamfers. This tap conforms to ANSI standards and can create threads to a depth 2 times its diameter. It is suitable for the ANSI 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.
