Milwaukee 48-89-4609 Titanium Drill Bit 3/16 in 5-pack

Product Description

The MILWAUKEE ELECTRIC TOOL CORP 48-89-4609 is a 3/16-inch titanium-coated drill bit engineered specifically for use with impact drivers. Sold in a 5-pack, these Shockwave Impact Duty bits feature a variable helix design with an aggressive 35-degree helix angle that transitions to 15 degrees. This geometry promotes rapid chip removal, reducing heat buildup and extending edge life. The 135-degree split point tip enables a precision start, eliminating walking and allowing fast, accurate hole placement. Titanium coating delivers up to three times the service life compared to standard black oxide drill bits.

These bits are suited for general drilling applications across residential and light commercial trades. The Impact Duty designation means they are built to withstand the rotational shock and torque cycling produced by impact drivers, making them a practical choice for electricians, HVAC installers, plumbers, and general contractors who rely on impact tools for speed. The titanium coating performs across wood, metal, and other common substrates encountered in typical trade work.

Key Features

• Variable helix design: 35-degree aggressive angle transitions to 15 degrees for rapid chip evacuation
• 135-degree split point tip eliminates walking for precise hole starts
• Titanium coating extends service life up to three times longer than black oxide bits
• Impact Duty construction handles the torque cycling of impact drivers
• Sold in a 5-pack for job-site redundancy

Compatibility

Designed for use with impact drivers and standard drill/drivers across general drilling applications where a 3/16-inch titanium bit is required.

Installation Notes

Installation and use should be performed by qualified tradespeople familiar with rotary drilling tools and impact drivers. Ensure the bit is fully seated and secured in the chuck or quick-connect collet before operation. Inspect bits for wear or damage before each use, and allow bits to cool between extended drilling cycles to preserve edge integrity. Follow all applicable tool manufacturer guidelines and jobsite safety requirements.
