Step drill bits are a wise investment for professional & do-it-yourself handymen and this 3-bit set is an excellent value. Drilling is more efficient - especially in hard steel - because the hole is cut in increments, with less stress on the bit, drill/impact driver and operator. Unlike regular, round shanks the hex quick-change shanks work in quick-change bit holders and popular small form-factor drills & impact drivers that have bit sleeve instead of chuck. Includes nylon storage pouch to keep bits protected & ready for next job. Dimensions: 13-step 3"H, 9-step 2-3/4", 6-step 3-1/2". Set weight 5 oz.

• Durable high speed steel with Titanium Nitride coating for faster & easier drilling
• Quick-change hex shanks fit impact drivers, quick-change bit holders and regular drill chucks
• Set of 3 bits covering 28 sizes: 13-step 1/8 to 1/2", 9-step 1/4 to 3/4" & 6-step 3/16 to 1/2"
• Drill more efficiently with less stress by cutting holes in incrementally-larger sizes
• Stop once desired size is reached, self-deburring; use on steel, metals, wood, plastic, fiberglass
