Milwaukee #7 Step Drill Bit, 7/8″ Single Hole

ELIMINATE BIT WALKING AND CHUCK SLIPPAGE

Engineered for the high-torque demands of modern cordless impact drivers and drills, the Milwaukee 48-89-9207 #7 Step Drill Bit represents a massive leap in accessory efficiency. By utilizing a dual-flute geometry, this bit provides superior chip evacuation and heat management, effectively doubling the cutting speed of standard bits while maximizing the holes-per-charge ROI on your M12 and M18 battery fleet. The black oxide coating serves as a critical barrier against thermal friction, ensuring the high-speed steel substrate maintains its edge even through repeated penetrations in heavy-gauge metals.

• / Rapid Strike Tip / Fast, accurate starts on contact that prevent bit walking and minimize surface marring.
• / Jam-Free Performance / Optimized dual-flute design prevents material buildup and stalling when used at high RPMs.
• / Laser-Engraved Marks / Permanent depth indicators provide at-a-glance hole sizing that won’t wear off over the life of the bit.
• / 3-Flat Secure-Grip Shank / Hex-optimized shank ensures 100% torque transfer and zero rotation inside the tool chuck.
