Milwaukee Thunderbolt Silver & Deming 1" Drill Bit 48-89-2754
HEAVY-DUTY BORE CAPACITY FOR TOUGH METAL APPLICATIONS
When you're stepping up to 1-inch diameter holes in high-tensile materials like stainless steel or cast iron, standard twist bits simply won't cut it. The Milwaukee Thunderbolt® Silver & Deming bit is engineered with a thicker web and a specialized parabolic flute geometry that significantly increases structural integrity. This design prevents the bit from snapping under the high-torque demands of large-diameter drilling while maximizing chip ejection to keep the cutting surface cool. The 135-degree split point is a critical feature for professional accuracy, ensuring the bit bites into the material immediately upon contact without the frustration of walking across the workpiece.
- / 135° Split Point Tip starts on contact to eliminate walking and provide a clean, precise entry point in hard metals.
- / Parabolic Flute Geometry clears chips and debris rapidly, reducing heat friction and extending the life of the cutting edge.
- / 3-Flat Secure-Grip™ Shank features milled flats to prevent the bit from spinning or slipping inside the chuck during high-torque applications.
- / Black Oxide Coating provides superior lubricity and corrosion resistance, ensuring the bit remains effective even in harsh jobsite environments.
- / Reduced 1/2" Shank allows this large 1" bit to be used in standard 1/2" drill chucks, offering maximum tool versatility.
