Milwaukee 19/32" Thunderbolt Silver & Deming Drill Bit 48-89-2741
INDUSTRIAL-GRADE BORE PERFORMANCE IN HIGH-TENSILE ALLOYS
Engineered for the rigors of high-tensile drilling, the Milwaukee Thunderbolt Silver & Deming bit utilizes a reinforced web design to withstand the lateral pressures that often snap standard bits in thick plate steel. The parabolic flute design is a critical mechanical advantage, acting as a high-speed conveyor for hot chips, which is vital when boring deep holes in cast iron or stainless steel where heat is the primary enemy of tool longevity. By reducing the shank to 1/2 inch and integrating three milled flats, this bit provides a mechanical lock that ensures maximum torque transfer without the risk of slipping in a standard drill chuck.
- / 135° Split Point Tip: Eliminates the need for a center punch by starting on contact, even on curved surfaces, ensuring a precision start every time.
- / Parabolic Flute Geometry: Engineered for rapid chip ejection, reducing heat buildup and extending the service life of the cutting edge in heavy-duty applications.
- / 3-Flat Secure-Grip™ Shank: Provides a mechanical lock in 1/2" keyed or keyless chucks to prevent bit spinning under high-torque loads.
- / Black Oxide Coating: Enhances lubricity and provides a critical layer of corrosion resistance for long-term jobsite durability in wet or harsh environments.
