Value Collection 01190081 Cobalt Jobber Drill Bit 1/8 in

Product Description

The VALUE COLLECTION 01190081 is a cobalt jobber-length drill bit designed for demanding metal-cutting applications. The 1/8 inch diameter bit features a 135-degree split point that reduces walking and requires no center punch on most surfaces. Cobalt construction provides the heat resistance needed when drilling stainless steel, hardened steel, and other tough alloys. The regular spiral flute geometry promotes efficient chip evacuation, and the bright straw finish indicates no additional coating is applied over the base cobalt material. This bit is suited for machinists, maintenance technicians, and fabricators working in industrial and trade environments.

This jobber drill bit is intended for use on stainless steel and hardened materials where standard high-speed steel bits lose their edge quickly. The straight cylindrical shank fits standard drill chucks and is compatible with handheld drill motors, drill presses, and CNC drilling operations. With a 1-5/8 inch flute length and 2-3/4 inch overall length, it is sized for typical through-hole and blind-hole work on light to medium stock. The right-hand cutting direction is standard for conventional drilling setups.

Key Features

• Cobalt construction rated for heavy-duty use in stainless steel and hardened materials
• 135-degree split point reduces thrust and eliminates center-punch requirement on most surfaces
• 1/8 inch diameter with 1-5/8 inch flute length for accurate, clean through-holes
• Right-hand, regular spiral flute promotes chip clearance and reduces heat buildup
• Straight cylindrical shank fits standard 3-jaw drill chucks without adapters
• No coolant-through design — suitable for external coolant or dry cutting applications

Compatibility

Designed as an OEM-style replacement or direct-use jobber drill bit for any application requiring a 1/8 inch diameter, straight-shank cobalt bit in drill presses, hand drills, or CNC drill fixtures.

Installation Notes

Installation of this bit is performed by machinists, fabricators, or maintenance trades familiar with metalworking equipment. Secure the straight shank fully in the drill chuck and tighten with a chuck key before operation. When drilling stainless steel or hardened material, use steady feed pressure and an appropriate cutting fluid to manage heat and extend bit life. Do not exceed the manufacturer-recommended RPM range for the diameter and material being drilled.
