Milwaukee 1" S&D Black Oxide Drill Bit

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.
