Milwaukee's Thunderbolt 7/8" Silver & Deming drill bit is built for demanding applications in stainless steel, cast iron, and other low to high tensile strength materials. The bit is manufactured from more→premium industrial-grade steel with heavy-duty cutting surfaces designed to power through deep and shallow holes alike. A specialized parabolic flute geometry reinforces the bit while keeping the bore clear of chips during operation. The 135-degree split point starts on contact, removing the need for a center punch. A 1/2-inch reduced shank with three Secure-Grip flats provides a firm hold in standard jawed chucks, and the black oxide coating adds both lubricity and corrosion resistance. The bit …

Milwaukee COBALT RED HELIX drill bits are engineered for extreme durability and long life in hard metal applications. Designed with a variable helix that includes an aggressive 35 helix angle which more→ends at 15 , the cobalt bits with RED HELIX provide Rapid Chip Removal limiting heat buildup to Stay Sharper Longer. The 135 split point tip delivers a precision start and prevents walking for fast, accurate holes. Ideal for tough applications and provide up to 10X life vs. Black Oxide Drill Bits but can be used in all twist drilling applications.

Milwaukee step drill bits with jam-free performance feature a dual-flute design delivering up to 2X faster hole times, up to 4X longer life and up to 50% more holes per battery charge than the competi more→tion. Ideal for drilling large and small-diameter holes in steel and plastic, these bits are optimized for cordless drills in high speed. The Rapid Strike tip allows for fast, accurate starts that generate less heat, resulting in longer bit tip life. Black oxide coating also enhances durability, hole quality and bit life. For user convenience and accuracy, each bit has laser-engraved reference marks you can see while drilling. The 3-flat Secure-Grip shank ensures a solid connection with the drill …
