Value Collection 01198464 Cobalt Jobber Drill No. 46

Product Description

The VALUE COLLECTION 01198464 is a cobalt jobber-length drill bit sized to wire gauge No. 46, with a decimal diameter of 0.0810 inches. It features a 135-degree split point that reduces walking on contact and lowers the thrust force needed to start a hole. The overall length is 2.125 inches, with a 1.125-inch flute length, and the straight cylindrical shank diameter matches the cutting diameter at 0.0810 inches. The straw finish is a byproduct of the cobalt heat treatment process and requires no additional coating. This bit is sold individually and is suited for use in standard drill chucks by machinists, maintenance technicians, and fabricators.

This bit is specifically designed for drilling stainless steel and other hardened materials where high-speed steel tooling loses its edge too quickly. The cobalt alloy construction maintains hardness at elevated temperatures generated during drilling into tough alloys. It is well-suited for production and maintenance environments where small-diameter precision holes are required in corrosion-resistant or work-hardening materials. The right-hand cutting direction and regular spiral flute geometry work with standard drill press and hand drill setups. Heavy-duty grade designation indicates suitability for demanding material applications beyond standard carbon or alloy steels.

Key Features

• Wire gauge No. 46 diameter at 0.0810 inches for precision small-bore drilling
• 135-degree split point reduces drill walking and lowers feed pressure on hard materials
• Cobalt alloy construction retains cutting hardness at high operating temperatures
• Right-hand spiral flute geometry clears chips efficiently during through-hole drilling
• Straight cylindrical shank compatible with standard drill chucks and collets
• Heavy-duty grade rating for use on stainless steel and hardened workpiece materials

Compatibility

Designed for drilling stainless steel and hardened materials. Fits any standard drill chuck or collet accepting a 0.0810-inch straight shank. Suitable for drill presses, CNC drilling operations, and hand drills where the chuck capacity accommodates this shank diameter.

Installation Notes

This bit is installed and removed by a qualified machinist or technician using a keyed or keyless chuck rated for the shank diameter. Secure the workpiece before drilling to prevent spinning or shifting. Use appropriate cutting fluid or coolant when drilling stainless steel to manage heat buildup and extend tool life. Follow applicable shop safety standards for rotating tooling, including eye protection and secure workholding.
