Milwaukee 48-89-2319 Cobalt Steel Red Helix Drill Bit

Milwaukee 48-89-2319 11/32" Cobalt Steel Red Helix Drill Bit

The Milwaukee 48-89-2319 is an 11/32" Cobalt Steel Red Helix drill bit built for professionals who need dependable performance when drilling through metal. Manufactured from solid cobalt steel, this bit is engineered to withstand the heat generated during high-speed drilling in hard and abrasive materials. The 11/32" (0.3438") diameter delivers a precise, consistent hole size for repeatable results job after job. Milwaukee's Red Helix flute geometry is designed to move chips away from the cutting edge quickly, reducing heat buildup and helping the bit stay sharper longer. Whether used in a production shop or on a job site, this cobalt steel bit is built to handle demanding metalworking tasks.

Key Features

• Trade Size: 11/32" (0.3438") diameter provides accurate, repeatable hole sizing for drilling applications that call for this exact bit size.
• Cobalt Steel Construction: Solid cobalt steel construction resists the heat and wear generated when drilling through stainless steel, cast iron, and other hard or abrasive metals, helping the bit maintain its cutting edge over repeated use.
• Red Helix Flute Design: Milwaukee's Red Helix flute geometry is engineered to evacuate chips more efficiently than standard flutes, helping reduce friction, keep the bit running cooler, and extend overall tool life.
• Consistent Performance: The combination of cobalt steel material and optimized flute design allows the bit to maintain sharpness and cutting performance through extended use in demanding metalworking environments.
• Professional-Grade Bit: Designed for tradespeople and metalworking professionals who need a reliable bit that can stand up to daily use in shops and on job sites.

Why Milwaukee?

Milwaukee engineers the 48-89-2319 from solid cobalt steel and pairs it with a Red Helix flute design specifically to meet the demands of professional metalworking. This construction helps the bit resist the heat and wear that quickly degrade standard drill bits when cutting through hard or abrasive metals, translating into longer bit life and more consistent hole quality over time. For professionals who rely on their tools to perform shift after shift, a cobalt steel bit with purpose-built flute geometry like the Red Helix offers the durability and cutting performance needed to keep jobs moving without constantly swapping out worn bits.
