Milwaukee 31/64" Thunderbolt Titanium Coated Drill Bit 48-89-2228

ENGINEERED THUNDERBOLT WEB FOR MAXIMUM RIGIDITY AND THERMAL RESISTANCE

When your high-torque drill drivers are pushing through heavy-gauge steel or dense lumber, the mechanical integrity of your bit is the difference between a clean hole and a snapped tool. The Milwaukee Thunderbolt Titanium Coated Drill Bit is engineered with a significantly thicker core than standard bits, providing the structural reinforcement needed to withstand the intense side-load pressures common in jobsite drilling. This design, paired with a parabolic flute, ensures rapid chip evacuation to prevent heat-soaking the material, while the titanium coating acts as a thermal barrier to maintain edge sharpness through hundreds of cycles. For professionals demanding a high ROI on their consumables, this bit delivers the durability required for consistent, high-speed production.

• / Thunderbolt Web Design: Features a thicker core to provide ultimate strength and protect against breakage under heavy side-loads.
• / Titanium Coating: Reduces friction and heat build-up, extending bit life by up to 3X compared to standard black oxide bits.
• / 135° Split Point: Delivers a precision start on contact, preventing bit walking on curved or flat surfaces for cleaner entry holes.
• / 3-Flat Secure-Grip™ Shank: Eliminates bit slipping in the chuck, ensuring maximum torque transfer from the motor to the cutting edge.
• / Parabolic Flute: Specifically shaped to clear chips and debris fast, keeping the bit cool and maintaining cutting efficiency.
