Value Collection 01190057 Cobalt Jobber Drill Bit 5/64 in

Product Description

The VALUE COLLECTION 01190057 is a cobalt jobber-length drill bit designed for heavy-duty drilling in hard and abrasive materials. Built from high-speed cobalt steel, it handles the heat and wear that standard HSS bits cannot. The 135-degree split point reduces walking at startup and lowers thrust force needed to start a hole. At 5/64 inch (0.0781 inch decimal) in diameter with a 2-inch overall length and a 1-inch flute length, this bit is suited for precision drilling in tight spaces. Right-hand cut with a regular spiral flute, it is sold individually and typically purchased in multiples of 12.

This bit is engineered for drilling stainless steel and other hardened materials where heat buildup and work hardening are primary concerns. It is a practical choice for HVAC technicians, plumbers, electricians, and fabricators who regularly drill into stainless sheet metal, hardened brackets, or structural components. The straight cylindrical shank fits standard keyless or keyed chucks on hand drills and drill presses. The straw finish is characteristic of cobalt-grade tooling and serves as a visual indicator of the material grade.

Key Features

• Cobalt construction rated for heavy-duty use in stainless steel and hardened materials
• 135-degree split point reduces bit walking and decreases required feed pressure
• Regular spiral flute promotes chip evacuation during drilling
• Right-hand cutting direction compatible with standard drill operation
• Straight cylindrical shank fits most standard drill chucks without adapters
• Compact 2-inch overall length suits confined or close-quarters applications

Compatibility

Designed as a standard jobber-length drill bit for use in hand drills and drill presses with chucks sized to accept a straight cylindrical shank at 5/64 inch diameter. Primary workpiece materials include stainless steel and hardened metals.

Installation Notes

Installation of this drill bit should be performed by a qualified tradesperson following applicable workplace safety guidelines. Secure the shank fully in the chuck and verify it is centered before operating the drill. Use appropriate cutting fluid or coolant when drilling stainless steel to reduce heat buildup and extend bit life, even though this bit does not support coolant-through delivery. Wear ANSI-rated eye protection during all drilling operations.
