Milwaukee 48-89-4605 Titanium Drill Bit 1/8 in 2 Pack

Product Description

The MILWAUKEE ELECTRIC TOOL CORP 48-89-4605 is a 2-pack of 1/8 inch Shockwave Impact Duty Titanium Drill Bits engineered specifically for use with impact drivers and impact drills. Each bit features a variable helix design with an aggressive 35-degree helix angle that transitions to a 15-degree angle, promoting rapid chip evacuation and reduced heat buildup during drilling. The 135-degree split point tip delivers a self-starting, accurate entry that resists walking on contact. The titanium coating extends service life up to three times longer compared to standard black oxide bits, making these a high-value option for trade professionals who drill frequently across multiple materials.

These impact duty drill bits are suited for electricians, plumbers, HVAC technicians, and general contractors who require reliable small-diameter drilling in wood, metal, plastic, and composite materials. The 1/8 inch diameter is commonly used for pilot holes, wire fishing setups, and fastener pre-drilling in tight or confined spaces. The Shockwave design is intended to absorb and redirect the torque pulses generated by impact drivers, reducing bit breakage in demanding jobsite conditions.

Key Features

• Variable helix with 35-degree to 15-degree angle transition for rapid chip removal and reduced heat
• 135-degree split point tip for precise, walk-free starts
• Titanium coating provides up to 3 times the service life versus black oxide drill bits
• Engineered for impact drivers and impact drills
• Suitable for all standard drilling applications including wood, metal, and plastic
• Sold as a 2-pack for extended jobsite use

Compatibility

Designed as an OEM-style replacement and general-use impact duty drill bit compatible with standard hex-shank impact drivers and impact drills across residential and commercial trade applications.

Installation Notes

These bits are installed by electricians, plumbers, HVAC technicians, and general contractors using standard impact drivers or drill drivers. Ensure the hex shank is fully seated and locked in the chuck or bit holder before operation. Do not use with corded or cordless drills that lack torque management if drilling hard metals, as overheating may reduce bit life. Inspect bits for wear or tip damage before each use and replace when cutting performance degrades.
