Milwaukee 48-89-4663 1/4 Inch Titanium Drill Bit 5-pack

Product Description

The Milwaukee Electric Tool Corp 48-89-4663 is a 5-piece pack of 1/4 inch Shockwave Impact Duty Red Helix Titanium Drill Bits engineered for use with impact drivers and high-torque drills. Built from titanium, these bits deliver increased surface hardness and extended bit life compared to standard high-speed steel. The Red Helix flute geometry is designed to evacuate chips faster and reduce heat buildup during repeated drilling cycles. This pack is well suited for electricians, plumbers, HVAC technicians, and general contractors who drill through wood, soft metal, and composite materials in fast-paced field or service work.

These drill bits are intended for professional tradespeople who rely on impact drivers as their primary drilling tool. The Shockwave designation indicates the bit shank is designed to absorb and redirect the rotational force produced by impact drivers, reducing the stress that causes standard bits to snap under load. A 1/4 inch hex shank provides quick-change compatibility with standard impact driver chucks. This 5-pack format is suited for crews and service vans where bit consumption is high and redundancy matters.

Key Features

• Titanium construction for improved hardness and extended service life over standard HSS bits
• Red Helix flute design accelerates chip evacuation and reduces heat during drilling
• Shockwave-rated shank absorbs impact driver torque to resist breaking and tip stripping
• 1/4 inch hex shank for direct, tool-free installation in standard impact driver chucks
• 5-piece pack provides job-site redundancy for high-volume drilling applications

Compatibility

Designed for use with standard 1/4 inch hex-chuck impact drivers and drill-drivers commonly used in electrical, plumbing, HVAC, and general construction trades.

Installation Notes

Insert the 1/4 inch hex shank fully into the impact driver chuck until the quick-release collar locks. Confirm the bit is seated and does not wobble before applying load. Always wear eye protection when drilling, as titanium bits operated at high RPM can eject chips and debris. Inspect bits for tip wear or shank deformation before each use and replace damaged bits immediately.
