Value Collection 01370204 5/16 Inch Cobalt Drill Bit

Product Description

The VALUE COLLECTION 01370204 is a screw machine length drill bit designed for heavy-duty metal drilling in tight-clearance applications. Built from cobalt steel with a straw finish, this bit delivers heat resistance and edge retention when cutting through hard or abrasive materials. The 135-degree split point initiates cutting without a center punch, reducing walking on smooth surfaces. At 2-13/16 inches overall length, the stub-style body provides rigidity and reduces deflection compared to jobber-length alternatives. Two regular spiral flutes evacuate chips efficiently during through-hole drilling. Machinists, millwrights, and maintenance technicians working with drill presses, lathes, or hand drills will find this bit suited to repetitive production drilling.

This bit is sized at 5/16 inches (0.3125 inches decimal) and fits within the 0.3000 to 0.3500 inch drill bit size range. The straight shank is compatible with standard three-jaw chucks and quick-change chuck systems. Its shorter overall length makes it appropriate for confined spaces, gang drilling fixtures, and CNC turret setups where standard jobber bits are too long. The right-hand cutting direction is compatible with conventional drill press and handheld drill operation. Cobalt construction makes this bit a practical choice for stainless steel, cast iron, titanium alloys, and other work-hardening materials.

Key Features

• Cobalt steel construction for extended tool life in hard and abrasive materials
• 135-degree split point for self-centering starts without a center punch
• Screw machine (stub) length at 2-13/16 inches OAL for rigidity and reduced deflection
• 1-5/8 inch flute length with regular spiral geometry for consistent chip evacuation
• Straight shank fits standard three-jaw and quick-change chuck systems
• Right-hand cutting direction for use with all standard drill equipment

Compatibility

Designed as a direct-fit replacement or stock drill bit for any three-jaw chuck or quick-change system accepting a straight-shank bit in the 5/16 inch diameter range.

Installation Notes

Installation of this drill bit should be performed by a qualified machinist or maintenance technician familiar with rotary cutting tools. Secure the straight shank fully in the chuck and verify concentricity before operation. Appropriate cutting fluid or coolant should be applied when drilling stainless steel or other work-hardening alloys to prevent premature edge wear. Always wear eye protection and follow applicable OSHA machine guarding requirements when operating drill presses or handheld drilling equipment.
