Value Collection 01-005 Cobalt Jobber Drill Bit No. 5

Product Description

The VALUE COLLECTION 01-005 is a cobalt jobber-length drill bit sized to No. 5 wire gauge, equivalent to 0.2055 inches in diameter. Built from heavy-duty cobalt high-speed steel and finished with a straw coating, this bit is engineered for drilling into stainless steel, hardened materials, and other tough alloys that would quickly degrade standard HSS tooling. The 135-degree split point self-centers on contact, reducing walking and the need for a center punch. With a 2-flute regular spiral design and an overall length of 3.75 inches, it fits standard drill chucks and CNC tool holders without modification.

This jobber drill is suited for general-purpose production drilling and maintenance applications where material hardness demands more than standard high-speed steel. Typical use cases include fabrication shops, mechanical contractors, and maintenance technicians drilling through stainless steel fasteners, brackets, and structural components. The straight cylindrical shank accepts both keyed and keyless chucks. The 2.5-inch flute length allows sufficient chip clearance at typical jobber drilling depths.

Key Features

• Cobalt high-speed steel construction handles stainless steel and hardened materials
• 135-degree split point self-centers and reduces thrust force at entry
• Straw finish provides mild heat and wear resistance during cutting
• Regular spiral flute promotes consistent chip evacuation in tough alloys
• Straight cylindrical shank fits standard drill chucks without adapters
• Heavy-duty grade rated for demanding production and maintenance drilling

Compatibility

Designed as a general-purpose jobber drill for use in any standard 3-jaw chuck, hand drill, drill press, or CNC machining center that accepts a straight-shank bit with a 0.2055-inch shank diameter.

Installation Notes

Installation and use of this drill bit should follow standard machine shop or field drilling procedures. Secure the workpiece and ensure the drill press or power tool is powered off and locked out before changing bits. Use appropriate cutting fluid or coolant when drilling stainless steel or hardened materials to extend tool life and manage heat buildup. Always wear appropriate eye protection and follow applicable shop safety codes during operation.
