Taper Tap Unified National Fine (UNF). High speed steel (HSS) taper tap. Includes 4-degree chamfer angle. 7-10 pitches chamfered and 8-10 tooth height. For use on hard materials.
I recently acquired a taper tap for my workshop and have been blown away by its effectiveness .The results are nothing short of exceptional and the quality of its construction IS undeniable. Industrial and Scientific cutting tools provide unparalleled options and their tapered tap is no exception. While the price point may be a bit steep, its durability and superior performance make it worth it..
This product exceeded my expectations when working on metal surfaces. The tapered design ALLOWED for easy threading and increased efficiency. The durability of the tool ensures long-lasting use in an industrial setting....
Pros
The only downside was the initial cost when compared to other drill bits.
Cons
Overall, highly recommend for anyone in need of reliable cutting tools in the Industrial and Scientific field.
Good quality. I had to drill and cut a non-hardened steel boring bar (still damn heavy) -- just very carefully and slowly so as not to break the tap in a deep hole. However, he did his job and created a small but important detail for a glider that will attempt to break the altitude record for winged aircraft.
