Milwaukee 5/8″ S&D Black Oxide Drill Bit

MAXIMUM CHIP EJECTION AND ANTI-SLIP PRECISION IN HEAVY METAL

Engineered for the rigorous demands of high-tensile drilling, the Thunderbolt Silver & Deming bit is a masterclass in mechanical durability. By utilizing a thickened core geometry, Milwaukee has effectively eliminated the common point of failure in large-diameter bits, providing a robust backbone that withstands the torsional stress of stainless steel and cast iron applications. The parabolic flute design is specifically calibrated to evacuate chips at a high velocity, preventing heat buildup and ensuring the cutting edges remain sharp through repeated cycles. For the professional looking to maximize their equipment’s ROI, this bit offers the perfect balance of speed and structural integrity.

• / 135 Split Point Tip starts on contact to eliminate walking and ensure precision hole placement without a center punch.
• / 3-Flat Secure-Grip Shank locks into the chuck to prevent bit slippage under high-torque loads.
• / Thunderbolt Web features a thicker core to provide superior strength and protect against side-load breakage.
• / Black Oxide Coating reduces friction and enhances lubricity for cooler operation and extended bit life.
• / 1/2″ Reduced Shank allows for large-diameter drilling using standard 1/2″ drill chucks.
