Milwaukee 48-89-4828 Shockwave Titanium Jobber Drill Bit

Product Description

The MILWAUKEE 48-89-4828 is a titanium-coated jobber-length drill bit engineered for use with both impacts and standard drills. It features a variable RED HELIX design with an aggressive 35-degree helix angle that transitions to 15 degrees, promoting rapid chip removal to reduce heat buildup and extend cutting edge life. The 135-degree split point tip provides a precise, self-starting entry and eliminates bit walking on smooth or hard surfaces. This bit is sold as a single unit and is sized to metric specifications. Electricians, plumbers, HVAC techs, and general trade contractors reach for this bit when drilling through metal, wood, and composite materials on the job.

This drill bit is suited for professional jobsite use where both impact drivers and standard drill-drivers are in rotation. The titanium coating delivers up to 3 times the service life compared to black oxide bits, making it a practical choice for high-volume drilling tasks. Its jobber length provides a balance of reach and rigidity appropriate for most through-hole drilling applications in metal framing, electrical rough-in, and mechanical installations. Metric sizing supports layout and hole-pattern work specified in metric dimensions.

Key Features

• Titanium coating rated for up to 3X life versus black oxide drill bits
• Variable RED HELIX design with 35-degree to 15-degree helix transition for rapid chip evacuation
• 135-degree split point tip for precise start and no walking on hard surfaces
• SHOCKWAVE impact-duty construction compatible with both impact drivers and standard drills
• Metric sizing for metric-specified hole patterns
• Sold individually, one bit per unit

Compatibility

Designed for use with standard hex-shank impact drivers and conventional keyed or keyless drill-drivers in jobsite drilling applications across metal, wood, and composite materials.

Installation Notes

Installation is performed by qualified trade professionals including electricians, plumbers, and HVAC technicians. Secure the workpiece before drilling and confirm the driver is set to an appropriate speed and torque range for the material. Inspect the bit for wear or tip damage before each use and replace when cutting performance degrades. Follow applicable NEC or IFGC clearance requirements when drilling near utilities or structural members.
