Product Information

These 4 or 5-star reviews represent the opinions of the individuals who posted them and do not reflect the views of Etsy. Die nuts, also known as rethreading dies, are dies made for cleaning up damaged threads, [8] have no split for resizing and are made from a hexagonal bar so that a wrench may be used to turn them. Now that you have a drilled hole, use the tap of the correct size and a tap handle to thread the hole.

Rethreading screwdrivers are a handy solution for use on switch boxes, conduit boxes, fittings and faceplates. This problem is particularly acute in blind holes, so thread forming is particularly suited to such applications.To overcome these problems, special tool holders are required to minimize the chances of tap breakage during tapping. HMT introduces the range of VersaDrive® ImpactaTaps and Impacta-DrillTaps which feature an extensive collection of high quality threading tools and thread taps. For a short while the turning will be wobbly but as the tap progresses downward into the hole, it will stabilize. Plug taps (same size as taper taps); Dies (same size as taper taps); Tap wrenches (M3-M12 x 1/16”-1/2”, M6-M20 x 1/4”-3/4”); Die wrenches (25mm x 1”, 38mm x 1-1/2” OD); T-type tap wrench (M3-M6) BUILT TO LAST: Constructed from chromium-coated high carbon steel for maximum strength and corrosion resistance; Metric tap set has 3-4 flute abrasive cutting edges each so you can easily clean/repair and cut materials such as aluminum, iron, cast iron, alloy steel, carbon steel, abrasive steel, malleable cast iron, and other difficult to machine metal materials EASY STORAGE: Heavy-duty 17” x 2.

Thus builders of, for example, locomotives, firearms, or textile machinery were likely to make their own taps and dies. In the US, they are commonly known as bottoming taps, but in Australia and Britain they are also known as plug taps. The work piece (blank) to be threaded, which is usually slightly smaller in diameter than the die's major diameter, is given a slight taper (chamfer) at the end that is to be threaded. Dies are used to cut threads on materials such as steel rods to allow a fitting to be screwed on and attached (threading). This instructable will focus on primarily the use of taper taps, although there will be some mentioning of bottoming taps.These stainless steel Swiss Made taps are grooved to make the job of creating threaded holes much simpler.

Threading taps are used in conjunction with a tap wrench so always consider the maximum side tap your wrench can hold when purchasing. Once you have used the taper tap to go either all the way through the hole, or as deep as a blind hole will allow, you can use a bottom tap (if available) to complete the threading closer to the bottom of the hole. We are happy to exchange or refund your purchase within 14 days providing the goods are in a fully resaleable condition. Tapping case studies with typical examples of tapping operations in various environments are shown on source machinetoolaid. Threading Taps are available in HSS (high-speed steel) and carbide and can be used by hand or machine.

Prior to drilling the hole you will eventually tap, determine what size you need to drill for the bolt you are trying to screw in.
