Milwaukee 48-89-4631 23pc Titanium Shockwave Drill Bit Set

Product Description

The MILWAUKEE ELECTRIC TOOL CORP 48-89-4631 is a 23-piece titanium drill bit kit built for professional drilling applications across metal, wood, and general-purpose materials. The set features a variable helix design with an aggressive 35-degree helix angle that transitions to 15 degrees, engineered for rapid chip evacuation and reduced heat buildup during extended drilling. A 135-degree split point tip delivers precise, walk-free starts without center-punching. The titanium coating provides up to three times the service life compared to standard black oxide bits. This kit is a core accessory for electricians, plumbers, HVAC techs, and general contractors who need a reliable, broad-range bit set on the job.

The 48-89-4631 is designed specifically for use with impact drills, making it compatible with the high-torque, hammering action that standard HSS bits cannot withstand. The red helix geometry is engineered to handle the rotational stress of impact drivers without premature failure. The 23-piece assortment covers a wide range of hole sizes from 1/16 inch through 1/2 inch, making it practical for rough-in work, fixture installation, panel work, and general fabrication tasks on residential and light commercial jobsites.

Key Features

• Variable helix design: 35-degree aggressive angle transitions to 15 degrees for rapid chip removal and reduced heat buildup
• 135-degree split point tip eliminates walking and delivers accurate, clean hole starts
• Titanium coating provides up to 3x longer service life compared to black oxide drill bits
• Red helix geometry engineered specifically for impact drill compatibility
• 23-piece assortment covers 1/16 inch through 1/2 inch in commonly used fractional sizes
• Suitable for use across all standard drilling applications including metal, wood, and plastics

Compatibility

Designed for use with impact drills and standard drill/drivers. Suitable for all drilling applications where titanium-coated HSS bits are appropriate, including metal, wood, and plastic substrates.

Installation Notes

Drill bits in this set should be installed and secured firmly in the chuck before operation. When drilling metal, use cutting fluid where applicable to further extend bit life and reduce heat. Inspect bits regularly for wear or chipping, and replace individual bits that show signs of dulling to maintain hole quality and jobsite safety.
