Guhring 9056460030000 Single Flute Gun Drill 3mm Carbide

Product Description

The GUHRING 9056460030000 is a single-flute gun drill bit engineered for precision deep-hole drilling in metalworking applications. Built from solid carbide with a nano-A tip coating, this drill maintains tight diameter tolerances to h5 and features a kidney-style coolant hole for through-coolant delivery directly to the cutting zone. The right-hand cutting geometry and web-thinned point reduce thrust force and improve chip evacuation in demanding bore operations. At a 3.00 mm cutting diameter and 105 mm flute length, it delivers a 25xD flute-to-diameter ratio suited for deep, accurate holes in general-purpose metalworking scenarios.

This drill bit is designed for use in CNC machining centers and gun drilling machines where through-coolant capability is required. The 6.00 mm straight shank seats securely in standard collet chucks and toolholders. It is appropriate for use in materials classified under K40 grade, typically covering cast irons and hardened non-ferrous alloys. Machinists and toolroom technicians working in production or precision job-shop environments will find this part fits single-flute gun drill tooling setups where hole depth and straightness are critical requirements.

Key Features

• Solid carbide construction with nano-A tip coating for extended tool life
• Through-coolant via kidney-style internal coolant hole for heat and chip management
• Single-flute gun drill geometry at 25xD ratio enables deep-hole drilling with minimal deflection
• h5 diameter tolerance ensures tight, repeatable bore sizing
• Web-thinned point reduces entry thrust and improves centering
• Right-hand cut, general-purpose material application across K40 grade workpieces

Compatibility

Designed as an OEM-style replacement and standard production tooling option for CNC machining setups requiring a 3.00 mm single-flute gun drill with a 6.00 mm straight shank and through-coolant capability.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool turret or spindle is locked before mounting or removing the drill. Seat the 6.00 mm shank fully in a clean, correctly sized collet or toolholder and torque the retention mechanism per the toolholder specification. Verify through-coolant supply lines are open and pressure is set per machine guidelines before initiating a cut.
