SAE Drill/Tap/Countersink Bit Set

This six-piece set combines drilling, tapping and countersinking in a single operation. Each bit is made from M2 high-speed steel with a bright uncoated finish. The right-hand threads follow UNC standards for common fastening tasks.

Suitable for SAE thread sizes #6-32 to 1/4-20

Mechanics and fabricators working with #6-32, #8-32, #10-24, #10-32, #12-24 and 1/4-20 threads can drill, tap and countersink without changing tools. Builders who need metric threads, left-hand threads or larger diameters must choose a different set.

M2 high-speed steel construction

The M2 steel provides the hardness and heat resistance required for repeated threading in steel and alloy. The bright finish shows wear clearly so the operator knows when replacement is needed. California Proposition 65 warnings apply to this product.

Questions about this item

Which thread sizes does the six-piece set include?

The set provides #6-32, #8-32, #10-24, #10-32, #12-24 and 1/4 in.-20 UNC right-hand threads.

What does the M2 steel construction mean when the bits are used in a drill?

M2 high-speed steel retains hardness at drilling temperatures, giving longer edge life in steel, aluminium and plastic than standard carbon steel bits.

How does the UNC thread standard affect compatibility?

UNC coarse pitch matches the most common North American tapped holes, so each bit threads directly into standard UNC nuts and pre-tapped holes.
