Guhring 9056410063500 Single Flute Gun Drill 1/4 in

Product Description

The GUHRING 9056410063500 is a single flute gun drill bit engineered for deep-hole drilling applications where chip evacuation, coolant delivery, and hole straightness are critical. Built from solid carbide in material grade K40, it carries a TiCN coating for heat resistance and extended tool life. The 6.35 mm (1/4 inch) cutting diameter is paired with a 16 mm shank, a 292 mm flute length, and a 340 mm overall length, giving it a 40xD flute-to-diameter ratio suited to deep-bore work. A kidney-style through-coolant configuration delivers cutting fluid directly to the tip under pressure. Web thinning reduces thrust force at entry. This tool is installed by machinists and tool-room technicians working in general-purpose metal removal operations.

This drill bit is designed for general-purpose material applications in production machining and job-shop environments. The single-flute gun drill geometry is typically used when drilling deep, straight holes in a single pass — eliminating the need for multiple-pass operations. The through-coolant system is required for proper chip flushing at depth. The 16 mm shank diameter is sized for collet chucks or dedicated gun-drilling machine spindles. Right-hand cutting direction is standard for conventional CNC machining centers and dedicated gun-drill equipment.

Key Features

• Solid carbide K40 grade construction for rigidity and wear resistance in deep-hole applications
• TiCN coating improves surface hardness and reduces thermal buildup at the cutting edge
• Kidney-style through-coolant bore delivers pressurized coolant directly to the cutting tip for chip evacuation
• Single flute gun drill geometry supports 40xD depth-to-diameter drilling in a single pass
• Web-thinned point reduces entry thrust and improves centering accuracy
• Right-hand cut, special point type — Series 5641

Compatibility

Designed for use in CNC machining centers and dedicated gun-drilling machines equipped with through-spindle coolant and a collet or tool holder accepting a 16 mm shank diameter. Suitable for general-purpose material applications per Series 5641 specifications.

Installation Notes

Installation and tool changes should be performed by qualified machinists with the machine spindle fully stopped and energy isolated per applicable lockout/tagout procedures. The through-coolant port must be connected to a pressurized coolant supply to prevent chip packing and tool breakage during deep-hole drilling. Verify shank seating depth and runout before initiating a cut. Do not run this tool without active coolant flow at the cutting tip.
