Value Collection 01-013 Cobalt Jobber Drill Bit No. 13

Product Description

The VALUE COLLECTION 01-013 is a No. 13 wire-size cobalt jobber drill bit designed for heavy-duty drilling in tough materials. Built from cobalt high-speed steel with a straw finish, it resists heat buildup during aggressive cuts. The 135-degree split point self-centers on contact, reducing walking and the need for a center punch. With an overall length of 3.5 inches and a flute length of 2.3125 inches, it handles standard jobber-depth holes in one pass. The straight cylindrical shank fits directly into standard drill chucks. This bit is suited for machinists, maintenance mechanics, and fabricators who work with hard or abrasive stock.

The 01-013 is built for drilling stainless steel and hardened materials where standard high-speed steel bits wear prematurely. Its cobalt construction and 135-degree split point geometry make it a reliable choice for production environments, job shops, and field service work where hole quality and bit longevity matter. The regular spiral flute pattern clears chips efficiently during through-hole and blind-hole operations. Right-hand cutting direction is standard for conventional drill press and hand-drill use.

Key Features

• Cobalt construction rated for stainless steel and hardened materials
• 135-degree split point self-centers and reduces walking on hard surfaces
• Straw finish provides moderate heat resistance and lubricity
• Regular spiral flute with 13xD flute-to-diameter ratio for efficient chip evacuation
• Straight cylindrical shank fits standard 3-jaw and keyless drill chucks
• Heavy-duty grade for general-purpose and demanding production use

Compatibility

Designed as a general-purpose jobber drill bit compatible with standard drill presses, CNC drilling machines, and portable hand drills equipped with a chuck sized for a 0.1850-inch straight shank.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or mechanics familiar with proper speeds and feeds for cobalt tooling in hard materials. Secure the shank fully in the chuck before operation and confirm the workpiece is clamped or fixtured. Use cutting fluid when drilling stainless steel or hardened stock to extend bit life and improve hole finish. Inspect the cutting edges before each use and replace if chipping or excessive wear is visible.
