Value Collection E1419003 Solid Pilot Counterbore 6mm

Product Description

The VALUE COLLECTION E1419003 is a solid pilot counterbore designed for precision countersinking and seat preparation in metalworking and machining applications. Built from cobalt steel for heat and wear resistance, this tool features a 6 mm cutting diameter, a 3.4 mm pilot diameter, and three flutes for clean, efficient material removal. The straight-cylindrical shank measures 0.219 inches in diameter, providing consistent tool holding in standard drill press and milling machine chucks. With an overall length of approximately 2.99 inches (76 mm), it handles typical countersinking tasks in production and job-shop environments. Machinists, toolmakers, and maintenance technicians use this tool when fastener seat accuracy is required.

This counterbore is suited for forward-cutting operations in ferrous and other hard materials where cobalt steel provides an advantage over standard high-speed steel tooling. It is sized for use with 3 mm fasteners, making it appropriate for light machine assembly, fixture work, and precision part fabrication in both manual and CNC-assisted setups. The three-flute geometry balances chip evacuation with surface finish quality, reducing chatter at the cutting seat.

Key Features

• 6 mm counterbore diameter sized for 3 mm fastener compatibility
• 3.4 mm pilot diameter for accurate seat alignment during cutting
• Three-flute design improves chip evacuation and reduces chatter
• Cobalt steel construction resists heat buildup in hard-material applications
• Straight-cylindrical shank at 0.219 inches fits standard toolholders
• Forward cutting direction compatible with conventional drill press and milling setups

Compatibility

Designed as a standard solid pilot counterbore for use with 3 mm fasteners in metalworking, machining, and fabrication applications requiring a piloted cutting seat.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom technicians familiar with rotating cutting tool safety. Secure the straight shank firmly in a compatible toolholder or chuck before operation and confirm runout is within acceptable limits. Power down the machine and release all stored energy before changing or inspecting the tool. Always use appropriate cutting fluid for the workpiece material to extend tool life and maintain cutting geometry.
