Milwaukee 29/32″ S&D Black Oxide Drill Bit

MAXIMUM TORQUE TRANSFER FOR LARGE-DIAMETER DRILLING

Professional-grade hole-making in high-tensile alloys demands more than just a sharp edge; it requires superior thermal management and mechanical grip. The Milwaukee 29/32″ Thunderbolt Silver & Deming bit is engineered for high-torque applications where standard bits often fail or slip. By utilizing a 135-degree split point, this bit eliminates the need for a center punch, biting into stainless steel or cast iron immediately upon contact. The parabolic flute geometry serves as the primary cooling mechanism, aggressively ejecting chips to prevent the heat buildup that destroys tool life in thick plate. With a 1/2″ reduced shank featuring three milled flats, this bit ensures that every bit of motor power is transferred to the cutting surface without the risk of spinning in the chuck.

• / 135 Split Point: Starts on contact to prevent walking and delivers cleaner, more accurate holes in hard metals.
• / Parabolic Flute Design: Maximizes chip ejection to keep the bit cool and extend cutting life during deep-hole applications.
• / 3-Flat Secure-Grip Shank: Prevents the bit from slipping in the chuck, ensuring consistent torque delivery under heavy loads.
• / Black Oxide Coating: Provides essential lubricity and superior corrosion resistance for long-term durability in industrial environments.
