Klein Tools Step Drill Bit 7/8″-1-3/8″

Drill larger, cleaner holes with the Klein Tools Step Drill Bit 7/8″–1-3/8″, engineered for professionals who demand precision, durability, and efficiency on the job. This high-performance step bit features dual spiral flutes that actively pull the bit through material, delivering faster cuts and smoother finishes across metal, plastic, and wood applications.

Constructed from high-speed steel and coated with aluminum titanium nitride, this bit offers up to 10X longer life than standard black oxide coatings while reducing heat buildup during use. The fast-starting split point tip minimizes walking, ensuring accurate hole placement without the need for a pilot hole.

Designed for jobsite versatility, the impact-rated 1/4″ hex shank provides a secure grip in both drills and impact drivers, while laser-etched markings make it easy to identify hole sizes quickly and accurately.
