Value Collection 01-006 Cobalt Jobber Drill Bit Size 6

Product Description

The VALUE COLLECTION 01-006 is a cobalt jobber-length drill bit designed for heavy-duty drilling in demanding materials. Ground to a 135-degree split point, it starts on contact without a center punch and reduces the thrust required to penetrate hard workpieces. The straw-coated cobalt construction provides elevated heat resistance compared to standard high-speed steel, making it well suited for sustained drilling cycles. With an overall length of 3.75 inches and a 2.5-inch flute length, it fits standard drill chucks and magnetic drill presses. Installation is performed by machinists, maintenance technicians, and fabricators working in general manufacturing or field service environments.

This drill bit is engineered for use in stainless steel and other hardened materials where a standard HSS bit would dull prematurely. The straight cylindrical shank accepts 13/64-inch collets and three-jaw chucks without modification. The regular spiral flute pattern evacuates chips efficiently at moderate feed rates, reducing heat buildup at the cutting edge. It is a general-purpose heavy-duty option for shops and field crews drilling wire-gauge holes in ferrous and high-alloy workpieces.

Key Features

• Cobalt construction for improved heat resistance and edge retention in hard materials
• 135-degree split point for self-centering entry and reduced thrust requirement
• Straw finish indicating cobalt-grade heat treatment
• 2.5-inch flute length with regular spiral for efficient chip evacuation
• Right-hand cutting with straight cylindrical shank diameter of 0.2031 inches
• No coolant-through design; suitable for dry or externally applied cutting fluid

Compatibility

Designed for use in standard three-jaw chucks and collet systems accepting a 13/64-inch straight shank. Intended for drilling stainless steel and hardened materials; not rated for masonry or non-ferrous soft materials where a different bit geometry is preferred.

Installation Notes

Secure the shank fully in the chuck before drilling and verify runout is within acceptable tolerance before starting the cut. Use an appropriate cutting fluid on stainless steel and hardened alloys to extend bit life and manage heat. Reduce feed rate if the bit squeaks or discolors, which indicates excessive heat at the cutting edge. Follow shop safety protocols including eye protection and secure workpiece fixturing at all times.
