Milwaukee RED HELIX 15PC Cobalt Drill Bit Set 48-89-2370
DOMINATE HARD METALS WITH ADVANCED RED HELIX METALLURGY
When drilling through stainless steel, cast iron, or thick-gauge structural metal, heat is the primary enemy of productivity. The 48-89-2370 Cobalt RED HELIX set is engineered to solve the thermal challenges of high-torque drilling. By utilizing a Cobalt alloy construction, these bits maintain their structural integrity at temperatures that would soften standard high-speed steel. The mechanical advantage is further enhanced by the Variable Helix flute geometry, which transitions from an aggressive 35° angle to a 15° exit, ensuring that chips are cleared instantly to prevent friction-based binding. For the professional looking to maximize ROI on consumables, these bits offer a 15X life cycle over black oxide alternatives, significantly reducing the cost-per-hole in the most demanding material applications.
- / QUAD EDGE Tip delivers a precision start without walking and features four cutting edges to create smaller chips for faster material removal.
- / VARIABLE HELIX Flute geometry clears debris rapidly to minimize heat buildup and extend bit sharp-life.
- / Thicker Tapered Web increases the internal core strength of the bit to prevent premature breakage under heavy side-loading or high-torque stalls.
- / 3-Flat Secure-Grip Shank on larger sizes prevents the bit from spinning in the chuck, ensuring maximum power transfer.
- / PACKOUT Compatible Case allows for seamless integration into your existing modular storage system for organized jobsite mobility.
