Milwaukee Elec Tool 48-89-4615 Titan Drill Bit 9/32 in 3-pack

Product Description

The MILWAUKEE ELEC TOOL 48-89-4615 is a 9/32-inch titanium-coated drill bit engineered for both impact driver and standard drill applications. Built on Shockwave technology, this bit uses a variable helix design that transitions from an aggressive 35-degree angle at the flute tip to a 15-degree angle near the shank. This geometry accelerates chip evacuation and limits heat buildup, keeping the cutting edge sharp through extended use. The titanium coating adds surface hardness, delivering up to three times the service life of standard black oxide drill bits. A 135-degree split point tip provides precise hole starts without walking. Sold in a 3-pack, making it a practical choice for contractors, electricians, and plumbers who go through bits regularly on the job.

This drill bit is suited for repetitive drilling tasks in residential and light commercial work. The variable helix and split point geometry make it effective across common trade materials including wood, sheet metal, and plastic. The Shockwave-compatible shank design handles the high-torque, high-vibration output of impact drivers without the bit cracking or deforming under load. Tradespeople running cordless impact drivers on rough-in and finish work will find the 9/32-inch diameter useful for conduit anchors, pipe hangers, and fixture mounting applications.

Key Features

• Variable helix angle: 35 degrees at tip transitioning to 15 degrees at shank for optimized chip removal
• Titanium coating provides up to 3 times the lifespan of standard black oxide bits
• 135-degree split point tip minimizes walking and enables fast, accurate hole starts
• Shockwave technology construction rated for impact driver and drill use
• Reduced heat buildup extends cutting edge sharpness over prolonged use
• Sold as a 3-pack (unit of measure: EA, package quantity: 3)

Compatibility

Designed as an OEM-style replacement or stock bit for trade professionals using standard hex-shank impact drivers and keyed or keyless chuck drills requiring a 9/32-inch diameter bit.

Installation Notes

A licensed electrician, plumber, or general contractor typically selects this bit for standard drilling tasks during rough-in or finish phases. Secure the bit fully in the chuck or impact driver before applying power. Allow the split point to seat before applying full feed pressure to avoid deflection. Inspect the cutting edge and titanium coating for wear periodically; discard bits that show chipping, deformation, or significant coating loss to maintain hole quality and prevent workpiece damage.
