Value Collection 01190040 Cobalt Jobber Drill Bit 1/16 in

Product Description

The VALUE COLLECTION 01190040 is a cobalt jobber-length drill bit designed for drilling into hard and abrasive materials where standard high-speed steel bits fall short. Built from heavy-duty cobalt steel with a bright straw finish, this bit features a 135-degree split point that reduces walking on contact and lowers thrust requirements at entry. The right-hand spiral flute design promotes efficient chip evacuation during through-hole operations. With a 1/16-inch diameter and 1-7/8-inch overall length, this bit is suited for precision small-diameter work in production and maintenance environments.

This bit is rated for use on stainless steel and hardened materials, making it a practical choice for HVAC technicians, pipefitters, electricians, and machinists who regularly drill into high-alloy or heat-treated workpieces. The straight cylindrical shank fits standard three-jaw chucks on drill presses, hand drills, and CNC drilling equipment. Typical applications include tap-size pilot holes, sheet metal penetrations in stainless enclosures, and general metalworking where heat resistance and edge retention are critical.

Key Features

• Cobalt steel construction resists heat buildup during extended drilling cycles in hard materials
• 135-degree split point reduces drill walking and lowers required feed pressure
• Regular right-hand spiral flute clears chips efficiently from the cutting zone
• Bright straw finish indicates heat-treated cobalt grade without added coating interference
• Straight cylindrical shank is compatible with standard drill press and hand-drill chucks
• Heavy-duty grade rated for stainless steel and hardened workpiece materials

Compatibility

Designed for use with stainless steel and hardened materials; fits standard three-jaw chucks accepting a straight shank at 1/16-inch diameter.

Installation Notes

Drill bit installation and use should follow standard metalworking safety practices. Secure the workpiece firmly before drilling and confirm the chuck is fully tightened around the shank. Use appropriate cutting fluid when drilling stainless steel or hardened alloys to manage heat and prolong edge life. Replace the bit at first sign of dulling to avoid work hardening the material surface.
