Milwaukee 48-89-4820 Shockwave Titanium Drill Bit

Product Description

The MILWAUKEE 48-89-4820 is a titanium-coated jobber length drill bit engineered for use with both impacts and standard drills. It features a variable RED HELIX geometry with an aggressive 35-degree helix angle that transitions to 15 degrees, promoting rapid chip removal and limiting heat buildup to extend cutting life. A 135-degree split point tip delivers a precise start and eliminates walking on contact. The titanium coating provides up to 3 times the service life compared to standard black oxide bits. Licensed HVAC technicians, electricians, plumbers, and general tradespeople use this bit for a wide range of metal and general-purpose drilling tasks.

This drill bit is sized in metric and is suited for residential and commercial jobsite applications where impact drivers or corded and cordless drills are the primary tools. The impact-duty construction handles the rotational stress and vibration produced by impact drivers without the tip chipping or the shank failing prematurely. The chip breaker design reduces heat accumulation during extended drilling runs, making it practical for repetitive production work and on-site fabrication tasks.
