Milwaukee Shockwave Impact Duty Electrical Step Bit Kit (48-89-9257)

Description

ELIMINATE SHANK FAILURE IN HIGH-VOLUME ROUGH-INS

When you’re punching through stainless enclosures or heavy-gauge junction boxes, you can’t afford a bit that walks or a shank that shears off under impact torque. This 3-piece SHOCKWAVE™ Impact Duty kit is engineered specifically for the industrial electrician who demands production-level speed and dead-on accuracy for conduit entries. By combining a Titanium Aluminum Nitride (TiAlN) coating with a reinforced SHOCKZONE™ body, these bits survive the high-heat, high-torque environments that melt standard HSS bits during long shifts.

• / TiAlN COATING: Delivers 5x longer life by significantly reducing heat friction in abrasive electrical materials.
• / SHOCKZONE™ SHANK: Optimized 1/4″ hex geometry absorbs peak torque to prevent premature breakage in impact drivers.
• / RAPID STRIKE™ TIP: Ensures fast, accurate starts without walking, even on curved surfaces or stainless panels.
• / DUAL SPIRAL FLUTE: Optimized for fast chip evacuation to keep the tool cool and prevent jamming during rapid-fire drilling.
• / LASER ENGRAVED SIZES: Permanent identification marks ensure you hit your conduit diameter every single time without guessing.
