High-speed steel is compatible with a variety of materials
Round shank with square end allows tap to be used in hand or power-driven applications
The Union Butterfield TN1500(UNC) TN1500(UNF) high-speed steel hand threading tap has 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) or UNF (Unified Fine). The straight flutes are suitable for threading through holes (extending through the workpiece) and blind or bottoming holes (with only one opening). 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.
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. The round shank with square end makes this tap suitable for hand or power-driven applications . 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 TN1500(UNC)/TN1500(UNF) series all taps have four flutes. They are available with a variety of chamfers. This tap conforms to ANSI standards and can create threads to a depth 1 Â½ times its diameter. It is suitable for the ANSI 3B tolerance class: 3B produces close-tolerance fasteners that resist loosening, 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
