Import Pulley Hand Tap 5/16-18, 6" O.A.L.

Spiral Pointed Tap Spiral point taps have an angled cutting face that forces material chips out ahead of the cut and a shallower flute passage, giving them more cross-sectional area. This offers greater strength, higher tapping speeds, and less power necessary to drive them.

ACME Tandem Tap An ACME Tap combines the initial roughing cut with the final finishing cut in a single pass to achieve an ACME screw thread. Thread pitches are generally coarse relative to diameters, so these taps are subjected to heavy chip loads.

Taper chamfer hand tap. 7 - 10 incomplete threads before cutting. Used in all types of hand and machine tool operations for ferrous and non-ferrous materials. Ground thread for better surface finish and tighter tolerances. Known as a starter tap. Best used for tapping a through hole, but may also be used in a blind hole that has ample clearance at the bottom of the hole. Also, effective when tapping hardened steels. Manufactured from high-speed steel. Use for tapping in carbon steel, alloy steel, stainless steel, cast iron, aluminum and non-ferrous materials. Made in the USA.

High Speed Steel TMX Spiral Point Ground Flute Hand Tap available with a plug chamfer (3-5 thread length). # 10 - 24 H3, Spiral Point, Plug Chamfer, HSS TMX Tap, Ground, 2 Flutes. Spiral point taps are designed to shoot the chips forward thus the alternate name of Gun Tap Forward chip ejection is recommended for through holes and will reduce double cutting of chips thus producing a good clean thread
