Milwaukee SHOCKWAVE Impact Duty #4 Step Drill Bit 48-89-4872

ELIMINATE TOOL CRIB WASTE

Engineered for the high-torque demands of the modern jobsite, the Milwaukee SHOCKWAVE Impact Duty Step Drill Bit #4 solves the common failure point of traditional accessories: impact-induced fatigue. For fleet managers and professionals focused on maximizing consumable ROI, this bit features a reinforced core and dual-flute geometry designed to manage heat and chip ejection simultaneously. Rather than replacing snapped bits every week, the specialized 1/4" hex shank and black oxide coating provide the mechanical resilience needed for repetitive hole-making in mild steel, aluminum, and PVC without sacrificing precision or speed.

• / DUAL-FLUTE OPTIMIZATION: Provides faster chip removal and prevents binding in heavy-gauge materials for cleaner hole production.
• / RAPID STRIKE TIP: Prevents bit walking and allows for immediate, accurate starts on slick surfaces without center punching.
• / IMPACT-READY SHANK: The 1/4" hex shank is specifically hardened to withstand the repetitive anvil strikes of impact drivers.
• / LASER-ETCHED MARKINGS: Ensures long-term size visibility that won't wear off under high thermal friction, reducing operator error.
