Chicago-Latrobe 46792 Cobalt Jobber Bit
This Chicago-Latrobe 46792 is a jobber-length drill bit made from cobalt steel for heavy-duty drilling in hard metals such as stainless steel and high-strength alloys. It suits professional mechanics, metal fabricators and maintenance technicians who need a durable bit that resists heat and wear during repetitive production or repair work.
Check shank fit and material suitability
Verify that your drill chuck accepts a straight shank of this diameter and that the machine delivers appropriate speed and torque for cobalt tooling. The bit is not coolant-through, so external lubrication or cutting fluid must be supplied when drilling deep holes or tough alloys. Confirm the 135-degree split point matches the hole-starting accuracy your application requires.
Cobalt construction with split-point geometry
The cobalt steel body maintains hardness at elevated temperatures, extending service life in abrasive or work-hardening materials. A 135-degree split point centres the bit without a centre punch and reduces thrust, improving control on curved or angled surfaces. The straw-bronze surface finish identifies the heat-treated cobalt grade and provides some corrosion resistance during storage and use.

Questions about this item
Does the Chicago-Latrobe 46792 cobalt jobber bit come as a single piece or in a set, and do I need a separate drill chuck?
The item is sold as an individual drill bit sized to letter V with a .3770 decimal equivalent; it fits any standard drill chuck that accepts jobber-length shanks, so no extra chuck is required.
When should I choose this 135-degree split-point cobalt bit instead of a general-purpose twist drill?
Choose it for drilling hard metals such as stainless steel or high-temperature alloys where the 135-degree split point reduces walking and the cobalt construction resists heat better than standard high-speed steel.
How does the 135-degree split point affect hole accuracy in a handheld drill?
The 135-degree split point centres itself on contact, minimising wander and producing straighter, cleaner holes in tough materials even without a drill press.
