Milwaukee 27/64″ THUNDERBOLTTitanium Drill Bit

MAXIMUM CORE REINFORCEMENT FOR HIGH-TORQUE METAL DRILLING

In high-production environments where bit failure leads to immediate downtime, the structural engineering of your consumables is paramount. The Milwaukee 48-89-2224 is built on the Thunderbolt® web platform, featuring a significantly thicker core than standard jobber bits to provide the lateral strength necessary to resist side-load breakage. This reinforced geometry, paired with a 135° split point, ensures that the bit engages the material instantly without walking, even on curved surfaces or hardened alloys. The titanium nitride coating acts as a critical thermal barrier, dissipating heat and maintaining edge sharpness through repeated high-RPM cycles in stainless steel, wood, and PVC.

• / Thunderbolt® Web Design: Engineered with a thicker core to provide ultimate durability and protect against snapping under heavy side-load pressure.
• / 135° Split Point Tip: Starts on contact to eliminate bit walking, delivering precision hole placement without the need for a center punch.
• / Titanium Coating: Reduces friction and heat build-up, extending the service life of the cutting edge by up to 3X compared to standard black oxide bits.
• / 3-Flat Secure-Grip™ Shank: Features three milled flats to prevent the bit from spinning in the chuck, ensuring maximum torque transfer during heavy drilling.
• / Parabolic Flute Geometry: Optimized spiral design clears chips and debris rapidly to prevent clogging and overheating in deep-hole applications.
