Value Collection 01-010 Cobalt Jobber Drill Bit No. 10

Product Description

The VALUE COLLECTION 01-010 is a No. 10 wire gauge cobalt jobber length drill bit built for drilling stainless steel, superalloys, and titanium. It carries a 135-degree split point that self-centers on contact and reduces the thrust force needed to start a hole. The straight cylindrical shank measures 0.1935 inches in diameter, and the overall length is 3.625 inches. Two spiral flutes run 2.4375 inches to clear chips efficiently during deep cuts. This bit is suited for machinists, maintenance technicians, fabricators, and trade professionals who regularly work with hard or work-hardening materials where standard high-speed steel bits wear quickly.

This bit is intended for general-purpose drilling in ferrous and high-strength materials, particularly stainless steel and exotic alloys. The jobber length format fits standard drill chucks on hand drills, drill presses, and CNC machining centers. Right-hand cutting direction is compatible with conventional machine spindle rotation. No coolant-through capability is present, so external cutting fluid or lubricant should be applied at the cutting face when drilling harder materials to extend tool life and maintain hole quality.

Key Features

• No. 10 wire size, 0.1935 inch decimal diameter — fits standard jobber chuck ranges
• 135-degree split point self-centers and reduces walking on hard surfaces
• Cobalt high-speed steel construction resists heat buildup in stainless steel and superalloys
• 2-flute spiral design with 2.4375 inch flute length promotes chip evacuation on deep passes
• Bright uncoated finish maintains consistent diameter tolerance without coating buildup
• Straight cylindrical shank accepts standard drill chucks without adapters

Compatibility

Designed as a general-purpose jobber length drill bit compatible with any standard 3-jaw drill chuck accepting a 0.1935 inch straight shank. Primary workpiece materials are stainless steel, superalloys, and titanium.

Installation Notes

Installed by machinists and trade technicians using a drill press, hand drill, or CNC spindle. Secure the shank fully in the chuck and verify runout before drilling. When working with stainless steel or titanium, apply cutting fluid continuously to prevent work hardening at the drill tip. Never allow the bit to spin without advancing into the workpiece, as rubbing without cutting generates heat that can degrade the cutting edge rapidly.
