Value Collection 02-065 Cobalt Jobber Drill Bit 1/8 in

Product Description

The VALUE COLLECTION 02-065 is a cobalt-grade, jobber-length drill bit designed for drilling into hard and abrasion-resistant materials in trade and industrial applications. Built from high-speed steel with cobalt content, it features a 135-degree split point that reduces walking and cutting pressure at entry. The 1/8 inch (0.1250 inch) diameter straight shank fits standard drill chucks without adapters. With an overall length of 2.75 inches and a flute length of 1.625 inches, this bit delivers a 13xD depth-to-diameter ratio suitable for general-purpose through-hole work. Right-hand cutting direction and a regular spiral flute promote consistent chip evacuation during operation.

This drill bit is suited for fabrication shops, mechanical contractors, and field technicians who regularly work with stainless steel, superalloys, and titanium. The split-point geometry eliminates the need for a center punch on most metals, making it practical for layout-critical work on HVAC components, structural fastener holes, and equipment brackets. It is sold individually and ordered in multiples of 12, making it a standard stocking item for tool cribs and service vans that see frequent small-diameter drilling tasks.

Key Features

• 135-degree split point reduces bit walking and lowers entry force on hard metals
• High-speed steel with cobalt content for improved heat and wear resistance
• Regular spiral flute with right-hand cut for consistent chip removal
• Straight cylindrical shank fits standard 3-jaw drill chucks directly
• 1.625-inch maximum drilling depth supports through-hole work on typical sheet and plate stock
• No coolant-through requirement — suitable for dry drilling with appropriate feeds and speeds

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any standard drill press, hand drill, or mill with a chuck capacity accommodating a 1/8 inch straight shank. Primary workpiece materials rated for this bit include stainless steel, superalloys, and titanium.

Installation Notes

This bit is installed and used by machinists, pipefitters, HVAC technicians, and mechanical contractors performing metal drilling tasks. Secure the shank fully in the chuck and verify runout before drilling into hard materials. When drilling stainless steel or superalloys, use appropriate cutting fluid to extend bit life and reduce work hardening at the hole entrance. Inspect the cutting edges before each use — cobalt bits subjected to excessive heat can develop micro-fractures that are not always visible.
