Guhring 9014520140000 Jobber Drill Bit 14mm Carbide

Product Description

The GUHRING 9014520140000 is a jobber length drill bit engineered from submicron solid carbide for demanding precision drilling applications. The bit measures 14 mm (0.5512 inches) in diameter with an overall length of 107 mm (4.21 inches) and a flute length of 66 mm (2.60 inches). A bright coating preserves the carbide substrate without altering cutting geometry. The 150-degree drill point angle and web-thinned, tapered web geometry reduce entry thrust and support clean penetration. Three spiral flutes evacuate chips efficiently. Licensed machinists, tool-and-die makers, and production drilling operations are the primary installers of this tooling.

This drill bit is suited for through-hole and blind-hole drilling in ferrous and non-ferrous materials where tight diameter tolerances are required. The straight-cylindrical shank seats in standard drill chucks and collet systems. With a diameter tolerance of -0.018 to 0.000 mm, it holds bore sizing consistent with precision machining standards. It conforms to DIN 6539 specification for solid carbide jobber drills and covers the size range of 12.50 mm to 15.00 mm within the GUHRING submicron carbide series. Coolant-through capability is not provided on this model.

• Bright coating maintains as-ground surface without added coating thickness
• Straight-cylindrical shank compatible with standard chucks and collet holders
• Conforms to DIN 6539 specification with diameter tolerance of -0.018 to 0.000 mm

Compatibility

Designed as a DIN 6539 solid carbide jobber length drill bit suitable for use in standard drill chucks and collet systems accepting a 14 mm (0.5512 inch) straight-cylindrical shank.

Installation Notes

This tooling is installed by machinists and CNC operators in drill press, machining center, or lathe applications. Power down and lock out the machine before changing tooling. Seat the shank fully and evenly in the chuck or collet and verify runout before beginning the cut. Consult the machine manufacturer and tooling guidelines for appropriate feeds, speeds, and clamping torque for the workpiece material.
