Bosch 1-Piece 5/32 In. x 3-1/8 In. Cobalt M42 Metal Drill Bit for Stainless Steel, Cast Iron, Titanium, Light-Gauge Metal, Aluminum

The Bosch Cobalt M42 metal drill bits are engineered with an upgraded M42 alloy, containing 8% cobalt. These hard-core Cobalt bits boast a 10x life expectancy compared to standard bits, and they are designed to withstand high-heat applications. The thick web-helix design of these bits delivers fast material removal and increased stability.

The bits that are 1/8 inch and larger feature a split point, while the bits that are 3/16 inch and larger feature a three-flat shank, both of which provide better bit grip. These Cobalt drill bits offer superior performance when drilling through stainless steel, cast iron, titanium, and other hard or abrasive metals.

The Cobalt M42 drill bits are engineered with an enhanced M42 alloy material that contains 8% cobalt, which delivers a 10x life expectancy compared to standard bits. These high-heat resistant bits can withstand extended periods of high-temperature applications.

The thick web-helix design of these bits provides additional stability when working with tough applications, and the surface-hardened tip allows for effective penetration of abrasive materials.

In summary, the Bosch Cobalt M42 metal drill bits are engineered with an upgraded M42 alloy, containing 8% cobalt, to deliver superior performance, durability, and heat resistance. The bits feature a split point or three-flat shank design for better grip, and the thick web-helix design and surface-hardened tip ensure stability and penetration in tough applications, making them ideal for drilling through stainless steel, cast iron, titanium, and other hard or abrasive metals.
