Milwaukee 21-Piece Thunderbolt Titanium Drill Bit Set 48-89-2226

MAXIMIZED CORE STRENGTH FOR HIGH-TORQUE DRILLING APPLICATIONS

Professional-grade drilling requires more than just a sharp edge; it demands a bit that can withstand the lateral pressures of handheld operation without snapping. The Milwaukee Thunderbolt Titanium series is engineered with a significantly thicker web than standard bits, providing the structural integrity needed to prevent breakage during deep-hole drilling or when the bit binds in dense material. The titanium coating acts as a critical thermal barrier, maintaining edge hardness during high-RPM cycles in stainless steel or thick-gauge metal. By utilizing a 135-degree split point, these bits eliminate the need for center punching, biting into the material immediately to ensure hole placement is precise every time, maximizing your productivity on the jobsite.

• / Thunderbolt Web: Thicker core design provides ultimate strength and protects against side-load breakage during aggressive drilling.
• / Titanium Coating: Reduces friction and heat build-up, allowing the bit to stay sharp up to 3X longer than standard black oxide bits for a better professional ROI.
• / 135° Split Point: Delivers a precision start on contact, preventing the bit from walking across smooth surfaces like pipe or sheet metal.
• / Secure-Grip™ Shank: 3-flat geometry on larger bits prevents spinning in the drill chuck under high torque, ensuring maximum power transfer.
• / Parabolic Flute: Optimized shape clears chips and debris rapidly to prevent clogging and further reduce thermal stress on the cutting edge.
