Milwaukee Elec Tool 48-89-4627 Titanium Drill Bit

Product Description

The MILWAUKEE ELEC TOOL 48-89-4627 is a 15/32 inch titanium-coated drill bit engineered for use with both impact drivers and conventional drills. Part of the SHOCKWAVE Impact Duty line, it features a RED HELIX variable-helix design that transitions from an aggressive 35-degree angle to 15 degrees. This geometry drives rapid chip removal, which reduces heat buildup and extends bit life. The 135-degree split point tip delivers accurate starts and prevents the bit from walking on contact. Titanium coating adds wear resistance, and Milwaukee rates this bit for up to three times the service life of standard black oxide bits. Licensed tradespeople and experienced DIYers will find it well-suited to demanding production drilling.

This drill bit is intended for drilling into a wide range of materials where heat buildup and premature wear are common failure points. The variable helix geometry makes it particularly effective in metal, wood, and composite substrates. At 15/32 inch diameter, it covers a common sizing need for conduit knock-outs, fastener clearance holes, and structural applications. The package contains 3 bits, providing redundancy for high-volume work on job sites where bit wear is a routine concern for electricians, plumbers, ironworkers, and general contractors.

Key Features

• Variable helix design: 35-degree aggressive angle transitions to 15 degrees for rapid chip evacuation
• 135-degree split point tip prevents walking and improves hole-start accuracy
• Titanium coating increases surface hardness and wear resistance
• Rated for up to 3 times the service life compared to black oxide drill bits
• Compatible with both impact drivers and standard drill/drivers
• Packaged as a 3-piece set for job-site redundancy

Compatibility

Designed as an impact-duty replacement or supplemental bit for use with standard hex-shank impact drivers and keyed or keyless chuck drills. No specific tool model restrictions are stated in available product data.

Installation Notes

Installation is performed by electricians, plumbers, ironworkers, and general tradespeople using standard drill/driver equipment. Secure the workpiece before drilling and use appropriate eye and hand protection. Reduce feed pressure when breaking through the back side of a workpiece to prevent grab or material tear-out. Inspect bit tips for wear before each use, as a damaged split point will compromise starting accuracy and increase heat.
