Milwaukee Step Drill Bit 3-Piece Set 48-89-9221

MAXIMIZED HOLE-MAKING PRODUCTION EFFICIENCY

Engineered to maximize the duty cycle of your high-speed cordless fleet, the Milwaukee 48-89-9221 Step Drill Bit Set eliminates the standard bottlenecks found in thin-gauge metal fabrication. By utilizing a dual-flute geometry specifically balanced for high-RPM cordless rotation, these bits significantly reduce heat friction—the primary killer of accessory lifespan—while delivering a burr-free finish that keeps production moving without the need for secondary deburring tools.

• / JAM-FREE PERFORMANCE: Dual-flute design ensures smooth chip evacuation for up to 2X faster hole times in professional-grade steel and plastic.
• / RAPID STRIKE™ TIP: Provides immediate, accurate starts without walking, preserving the integrity of your workpiece and extending bit tip life.
• / CORDLESS OPTIMIZATION: Specifically tuned for high-speed drilling, delivering up to 50% more holes per battery charge than competitive bits.
• / LASER-ENGRAVED MARKS: High-visibility reference points allow for precise depth control and hole sizing while the bit is in motion.
• / SECURE-GRIP™ SHANK: Three-flat design prevents the bit from slipping in the chuck under high-torque drilling applications, protecting your drill's internal components.
