Milwaukee #9 Step Drill Bit, 7/8″ & 1-1/8″

MAXIMIZED HOLE-MAKING PRODUCTIVITY

Engineered for the high-torque demands of modern impact drivers and high-speed cordless drills, the Milwaukee 48-89-9209 #9 Step Drill Bit delivers a masterclass in metal penetration. By utilizing a specialized dual-flute geometry and a Rapid Strike Tip, this bit mitigates heat buildup and eliminates the ‘walking’ common with lesser bits. Whether you are punching through sheet metal or stainless, the black oxide finish ensures a low-friction surface that resists corrosion and maintains edge retention over thousands of cycles, maximizing your fleet’s return on investment.

• / Rapid Strike Tip: Ensures immediate engagement without center punching, saving critical seconds on every layout.
• / Dual-Flute Geometry: Optimized specifically for cordless platforms to provide jam-free performance and up to 2X faster cutting speeds.
• / Black Oxide Coating: Advanced surface treatment reduces thermal friction and protects against oxidative wear in harsh environments.
• / Laser-Engraved Reference Marks: Permanent visibility of hole sizes prevents guesswork and ensures precision depth control on every bore.
• / 1/4″ Hex Shank: Provides a secure, no-slip connection in impact drivers while maintaining compatibility with standard 3-jaw chucks.
