Milwaukee 15/32" Thunderbolt Titanium Coated Drill Bit 48-89-2227

REINFORCED WEB GEOMETRY FOR MAXIMUM RIGIDITY AND THERMAL CONTROL

The Milwaukee 48-89-2227 15/32" Thunderbolt bit is engineered to solve the primary failure point of standard jobber bits: side-load breakage. By utilizing a significantly thicker core—the Thunderbolt web—this bit maintains structural integrity under heavy torque and lateral pressure, making it ideal for deep-hole drilling in tough materials. The titanium nitride coating is a critical performance layer that actively manages thermal buildup, ensuring the cutting edge remains sharp through repeated cycles in abrasive materials like stainless steel or thick PVC. For the professional user, this mechanical design translates to a lower cost-per-hole and significantly reduced downtime caused by snapped bits.

• / THUNDERBOLT WEB: Features a thicker core than standard bits to provide ultimate strength and protect against side-load breakage.
• / TITANIUM COATING: Reduces heat build-up and maintains edge sharpness for up to 3X longer life compared to standard high-speed steel.
• / 135° SPLIT POINT: Delivers a precision start on contact and prevents bit walking for faster, more accurate holes in metal and wood.
• / PARABOLIC FLUTE: Specially designed form clears chips and debris rapidly to prevent clogging and keep the bit cool.
• / 3-FLAT SECURE-GRIP™ SHANK: Prevents the bit from spinning or slipping in the drill chuck under high-load applications.
