Milwaukee 29/64" Cobalt RED HELIX Drill Bit 48-89-2326
MAXIMUM HEAT RESISTANCE FOR HARD METAL PENETRATION
When you're drilling through stainless steel, cast iron, or thick-gauge structural steel, heat is the primary enemy of your cutting edge. The Milwaukee 29/64" Cobalt RED HELIX bit is engineered specifically to combat thermal breakdown in high-torque applications. By utilizing a variable helix geometry—starting at an aggressive 35° and tapering to 15°—this bit clears chips at an accelerated rate, preventing the friction-induced welding of material to the flutes. The cobalt alloy construction maintains its structural integrity at temperatures where standard high-speed steel would soften, ensuring a professional ROI through significantly extended service life in abrasive materials.
- / 135° Split Point: Eliminates bit walking on hard surfaces for precise hole placement without the need for a center punch.
- / Variable RED HELIX™ Flute: Optimizes chip evacuation to reduce heat buildup and maintain cutting edge sharpness for up to 15X longer than black oxide.
- / QUAD EDGE™ Tip: Features four cutting edges to create smaller, manageable chips for faster material removal and lower operating temperatures.
- / 3-Flat Secure-Grip™: The reduced 3/8" shank features three flat sides to prevent the bit from spinning or slipping in the chuck under heavy load.
