Milwaukee 1" S&D Black Oxide Drill Bit

Description

Milwaukee's Thunderbolt Silver & Deming drill bits are designed for performance in low to high tensile strength materials, stainless steel and cast iron. Thunderbolt twist drill bits are made from premium industrial-grade steel with heavy-duty cutting surfaces that power through deep or shallow holes with lightning speed. A special flute geometry adds strength while providing increased chip ejection. Thunderbolt twist drill bits have a heavy duty 135 degree split point for easy penetration and a 1/2 in. reduced shank with 3 milled flats which prevent slippage in a jawed chuck. One per package.

Features

• Corrosion resistant: Black oxide coating provides lubricity and resists corrosion of the bit
• Fast, accurate drilling: 135 split point tip starts on contact to prevent walking, while the parabolic flute clears chips fast
• Reduced slipping: 3-Flat Secure-Grip™ shank holds the bit firmly in the drill chuck
