Milwaukee 5/16 x 10 x 12 Carbide Hammer Drill Bit 48-20-9017
EXTENDED REACH PRECISION MASONRY DRILLING
When you're drilling deep anchor holes in cured concrete or masonry, bit walking and heat buildup are your biggest enemies. This 12-inch extended bit is engineered to stay on point with a precision ground tip and a wide flute design that clears dust efficiently to keep the cutting edge cool. Whether you're working with a corded or cordless hammer drill, the 3-flat shank ensures the bit stays locked in the chuck under high-torque loads.
- / Sharpened carbide edges deliver up to 5x life in concrete and 2x faster drilling in masonry material.
- / Precision ground carbide tip minimizes bit walking for more accurate hole placement in block and brick.
- / Wide flute design aggressively clears dust to reduce heat and maximize holes per battery charge.
- / 3-Flat Secure Grip shank prevents the bit from slipping in the chuck during heavy-duty hammer applications.
