Milwaukee 17/32" Thunderbolt Black Oxide Silver & Deming Drill Bit 48-89-2739

INDUSTRIAL-GRADE PRECISION FOR HIGH-TORQUE METAL BORING

When your project demands a hole diameter that exceeds standard drill bit sets, the Milwaukee Thunderbolt® Silver & Deming series provides the mechanical advantage needed for clean, accurate results in tough alloys. This 17/32" bit is specifically engineered with a thick web core to handle the high torsional loads of large-diameter drilling without snapping. The black oxide coating provides the essential lubricity to reduce heat buildup in stainless steel and cast iron, significantly extending the tool's service life. With a reduced 1/2" shank featuring three milled flats, this bit ensures that all the torque from your drill is transferred directly to the cutting edge, eliminating the common frustration of bit slippage in the chuck.

• / 135° Split Point Tip: Delivers immediate penetration on contact, preventing bit walk and ensuring precision starts in high-tensile materials.
• / Parabolic Flute Geometry: Engineered for rapid chip ejection, which keeps the cutting edge cool and prevents clogging during deep-hole applications.
• / 3-Flat Secure-Grip™ Shank: Provides a rock-solid connection in any 1/2" keyed or keyless chuck, preventing the bit from spinning under heavy loads.
• / Thunderbolt® Web Design: Features a reinforced core that provides superior strength and durability compared to standard twist bits.
• / Black Oxide Lubricity: Resists corrosion and reduces friction, allowing for faster drilling speeds and longer intervals between sharpenings.
