Milwaukee Step Drill Bit 6-Piece Set 48-89-9224
MAXIMIZED HOLE-MAKING EFFICIENCY
Engineered for the high-volume professional, the Milwaukee 48-89-9224 Step Drill Bit Set is a masterclass in thermal management and mechanical geometry. By utilizing a dual-flute design specifically tuned for high-speed cordless operation, these bits slash cycle times while extending the runtime of your M18 or M12 fleet. The integration of the Rapid Strike™ tip eliminates bit walk on smooth surfaces, ensuring that every penetration is precise, repeatable, and requires minimal physical force from the operator.
- / JAM-FREE PERFORMANCE: Dual-flute geometry prevents material binding in high-speed applications for seamless hole creation.
- / RAPID STRIKE TIP: Facilitates immediate starts without center punching, reducing heat buildup for 4X longer tool life.
- / OPTIMIZED FOR CORDLESS: Engineered to deliver 50% more holes per charge, maximizing the ROI of your existing battery platforms.
- / SECURE-GRIP SHANK: Three-flat design prevents the bit from slipping in the chuck, ensuring consistent torque transfer.
- / LASER-ENGRAVED REFERENCE: Permanent, easy-to-read marks allow for precision depth control while the bit is in motion.
