Titanium-Nitride Coated Step Drill Bit – 10-Size Range (1/4″–1-3/8″), Hss Core

Description

One cone-shaped bit, ten hole sizes. This titanium-coated HSS step bit drills and expands holes from 1/4″ to 1-3/8″ in 1/8″ increments — no bit changes, no re-chucking. The 135-degree split-point tip self-starts without walking, and the two-flute spiral design deburrs as it cuts.

Works on steel, stainless steel, copper, aluminum, plastic, and wood. 3/8″ tri-flatted shank locks into any standard chuck.

10 Sizes in One Bit Drills holes from 1/4″ to 1-3/8″ in 1/8″ increments. Sizes engraved on the bit for easy identification.

Titanium Nitride Coating HSS alloy steel with TiN coating for heat resistance, durability, and extended cutting life on metal and hard materials.

Self-Starting Split Point 135-degree split-point tip starts on contact without center punch or pilot hole. Two-flute spiral clears chips automatically.
