About Drillco 2000N Series High Speed Steel Thread
The Drillco 2000N black oxide high-speed steel hand threading tap has straight flutes and a round shank with a square end, and is used to create right-hand threads in a range of materials. In is available in two different thread specification standards: UNC (Unified Coarse) or UNF (Unified Fine). 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.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 it 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 Drillco 2000N series, taps are available with two to six flutes. Taps in this series are available in a variety of chamfers. Taper chamfers have a 7-10 pitch chamfer length and are used to start the thread square with the workpiece. Plug chamfers have a 3-5 pitch chamfer length and are generally used for through holes. Bottoming chamfers have a 1-2 pitch chamfer length for generating the thread to the bottom of the hole.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
