Milwaukee 1-1/4" Thunderbolt Silver & Deming Drill Bit 48-89-2758
HEAVY-DUTY LARGE DIAMETER METAL BORING WITH MAXIMUM CHUCK SECURITY
Engineered for high-torque applications in stainless steel, cast iron, and high-tensile alloys, the Milwaukee Thunderbolt® Silver & Deming bit is a masterclass in mechanical durability. The core of this bit features a thicker Thunderbolt web, providing significantly higher torsional strength to resist snapping under heavy loads. By utilizing a 1/2" reduced shank with three milled flats, this bit allows for 1-1/4" hole production using standard 1/2" drill chucks without the risk of the bit spinning or slipping during high-resistance cuts. The black oxide coating is not just for aesthetics; it provides essential lubricity to reduce heat buildup, extending the life of the cutting edges during repetitive drilling cycles in hard metals.
- / 135° Split Point Tip starts on contact to eliminate walking and ensures immediate penetration in hard materials.
- / 3-Flat Secure-Grip™ Shank provides a mechanical lock in the chuck to prevent bit slippage under high torque.
- / Parabolic Flute Geometry clears chips and debris rapidly to prevent clogging and heat-related edge dulling.
- / Black Oxide Coating offers superior corrosion resistance and reduces friction for faster drilling speeds.
