Description

T200 M42 Cobalt Jobber Drill Bits – 1/16″ to 1/2″, USA Made

T200 M42 Cobalt Jobber Drill Bits are made for serious metal cutting. Manufactured in the USA from premium M42 high-speed steel with 8% cobalt, these drill bits are engineered to power through the toughest materials—stainless steel, Inconel, titanium, tool steels, and hardened alloys.

Each bit is built to NAS 907J aerospace specifications and fully ground for precision. The 135° split point tip ensures fast starts, reduced walking, and clean hole drilling without the need for a pilot. With a bright gold finish and razor-sharp edge retention, these drills cut cleaner and last longer than standard HSS or M35 cobalt bits.

This T200 series runs from 1/16″ to 1/2″ in 1/64″ increments. Sizes 1/16″ through 19/64″ are sold in packs of 12, and sizes 5/16″ and above are sold in packs of 6.

Ideal for machinists, fabricators, and pros who need bits that hold up under heavy feed pressure and heat.

Built for production environments, field work, or garage fab tables, these jobber-length cobalt drills give you the rigidity, heat resistance, and accuracy to keep cutting day in and day out.
