Milwaukee 23/32" Thunderbolt Silver & Deming Drill Bit 48-89-2745
MAXIMUM RIGIDITY FOR LARGE-DIAMETER BORE HOLES
The Milwaukee Thunderbolt® Silver & Deming drill bit is engineered for high-performance drilling in low to high tensile strength materials, including stainless steel and cast iron. Featuring a thicker web than standard twist bits, the Thunderbolt core provides superior structural integrity, allowing the bit to withstand heavy side-load pressure without snapping. The 135° split point tip ensures the bit starts on contact, eliminating walking on curved or flat surfaces, while the parabolic flute geometry rapidly ejects chips to prevent heat buildup. Designed with a 1/2" reduced shank and 3-Flat Secure-Grip™ flats, this bit provides maximum torque transfer and prevents slippage in the chuck, making it an essential high-ROI accessory for heavy-duty metal fabrication.
- / Thunderbolt® Core: Thicker web design provides increased strength and protects against breakage during deep-hole applications.
- / 135° Split Point: Precision tip starts on contact to prevent walking and delivers faster penetration in hard metals.
- / Parabolic Flute: Specialized geometry clears chips fast to reduce heat and extend the life of the cutting edge.
- / Secure-Grip™ Shank: 3-flat reduced 1/2" shank prevents the bit from spinning in the chuck under high-torque loads.
- / Black Oxide Coating: Provides essential lubricity and resists corrosion for long-term jobsite durability.
