Milwaukee's Thunderbolt 5/8" Silver & Deming drill bit is built from premium industrial-grade steel to handle demanding drilling applications. The bit cuts cleanly through low and high tensile strengt more→h materials, stainless steel, and cast iron. A black oxide coating adds lubricity during cutting, reducing friction and protecting the bit against corrosion. The specially shaped flute channels chips away from the cutting zone quickly, keeping holes clean during both shallow and deep drilling. Milwaukee's 135-degree split point starts on contact, so the tip grips the workpiece immediately without walking. A 1/2-inch reduced shank with three milled flats is designed for use in standard jawed chucks.…

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 …
