Milwaukee 19/64" Thunderbolt Titanium Coated Drill Bit 48-89-2216

MAXIMUM DURABILITY FOR HIGH-SPEED METAL DRILLING

Engineered for the professional who demands longevity in high-torque applications, the Milwaukee 19/64" Thunderbolt Titanium Coated Drill Bit is built to withstand the rigors of heavy-duty drilling. The core of this bit features the proprietary Thunderbolt web, a thicker cross-section that provides superior strength against side-load breakage—a common failure point in standard bits. By utilizing a titanium coating, this bit effectively manages heat friction, maintaining a sharp edge up to three times longer than traditional high-speed steel. Whether you are drilling through thick plate steel or curved surfaces, the 135-degree split point ensures an immediate start without the need for a center punch, while the parabolic flute geometry clears chips rapidly to prevent binding and overheating.

• / Thunderbolt Web: Thicker core design provides ultimate strength and protects against side-load breakage during aggressive drilling.
• / Titanium Coating: Reduces heat build-up and maintains sharpness for up to 3X longer life compared to standard black oxide bits.
• / 135° Split Point: Delivers a precision start on contact to prevent bit walking on flat or curved surfaces.
• / Secure-Grip™ Shank: 3-flat shank design prevents the bit from slipping in the drill chuck under high-torque loads.
• / Parabolic Flute: Specially designed geometry clears chips and debris faster to keep the bit cool and improve drilling speed.
