1/8 in. - 1/2 in. IMPACT READY Titanium-Nitride Coating Step Drill Bit | DEW-DWA1783IR

DEWALT's 1/8 in. - 1/2 in. IMPACT READY Titanium Nitride Coating Step Drill Bit provides 13 clearly marked hole sizes in 1/32 in. increments, allowing multiple drilling diameters from a single bit. Laser-engraved size markings improve step visibility, while the high-speed steel construction and titanium nitride finish support repeated drilling in suitable materials. The bit reaches a maximum hole diameter of 1/2 in. and provides a maximum drilling depth of 1 in., with an overall length of approximately 3-3/8 in. Its impact-ready design is optimized for impact-driver use while remaining compatible with conventional rotary drills.

• Titanium nitride coating and dual-flute spiral design support longer service life and efficient chip removal
• Split-point tip starts on contact to help improve drilling speed and accuracy
• Thirteen laser-engraved steps provide hole sizes from 1/8 in. to 1/2 in. in 1/32 in. increments
• 1/4 in. hex shank is optimized for impact drivers and compatible with rotary drills
• High-speed steel construction provides a durable cutting edge for electrical, HVAC, mechanical, and installation applications
