Milwaukee RED HELIX 23PC Cobalt Drill Bit Set 48-89-2338
EXTREME HARD-METAL PENETRATION
For fleet managers and contractors looking to maximize ROI on consumables, the Milwaukee RED HELIX Cobalt Drill Bit Set is the benchmark for high-volume metal fabrication. These bits aren't just an accessory; they are a mechanical solution for the most demanding substrates, specifically engineered to conquer stainless steel, cast iron, and thick-gauge structural metals where standard black oxide bits fail instantly. By integrating a variable helix design that transitions from 35 degrees to 15 degrees, Milwaukee ensures that chip evacuation is optimized to prevent heat-soak, significantly extending the service life of every bit in the kit.
- / QUAD EDGE TIP: Features four distinct cutting edges to create smaller chips, reducing friction and heat buildup during high-speed engagement.
- / 15X DURABILITY: Cobalt construction provides superior thermal resistance compared to standard bits, delivering up to 15X life expectancy in abrasive metals.
- / TAPERED WEB DESIGN: An internally thicker core increases the bit's torsional strength, drastically reducing snapping under high-torque load.
- / PACKOUT COMPATIBILITY: Housed in a customizable accessory case that locks directly into the Milwaukee PACKOUT storage ecosystem.
