Milwaukee SHOCKWAVE Impact Duty Electrical Step Bit Kit 48-89-9257

Milwaukee SHOCKWAVE Impact Duty Electrical Step Bit Kit 48-89-9257

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 SHOCKWAVEā„¢ 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 SHOCKZONEā„¢ 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.
  • / SHOCKZONEā„¢ SHANK: Optimized 1/4" hex geometry absorbs peak torque to prevent premature breakage in impact drivers.
  • / RAPID STRIKEā„¢ 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.
