Guhring 9007680145000 Straight-flute Drill Bit 14.50mm

Product Description

The GUHRING 9007680145000 is a straight-flute solid carbide drill bit engineered for high-performance drilling in aluminum, aluminum alloys, and cast iron. Built from submicron-grade carbide, this bit delivers consistent dimensional accuracy with a diameter tolerance of +0.007 to +0.025 mm. The 120-degree standard point geometry and web-thinned tip reduce cutting forces and improve centering at entry. At 14.50 mm in diameter with a 16.00 mm shank, this drill fits standard toolholders conforming to DIN 6535HA. Coolant-through capability via a round coolant-hole channel keeps the cutting zone clear and helps extend tool life in demanding production environments. Licensed HVAC techs, machinists, and industrial maintenance professionals working with non-ferrous and gray iron materials will find this drill a reliable production tool.

This drill bit is designed for use in CNC machining centers and rigid drilling setups where repeatability and hole quality matter. The 4xD flute-to-diameter ratio provides adequate chip evacuation in shallow-to-moderate depth holes. The bright, uncoated finish is well suited for aluminum and aluminum alloy applications where coatings can cause material adhesion. The right-hand cutting direction is standard for conventional spindle rotation. Series 768 from GUHRING targets high-output environments where tool change frequency and cost-per-hole are closely managed.

Key Features

• Submicron solid carbide construction for extended wear resistance in non-ferrous and cast iron materials
• 120-degree standard point angle with web-thinned geometry for reduced thrust and accurate entry
• Coolant-through design with round coolant holes for effective chip and heat management
• Bright, uncoated finish minimizes built-up edge when drilling aluminum and aluminum alloys
• DIN 6535HA shank specification ensures compatibility with precision collet and hydraulic toolholders
• Diameter tolerance of +0.007 to +0.025 mm supports tight-tolerance hole production

Compatibility

Designed for use in rigid CNC drilling applications targeting aluminum, aluminum alloy, and cast iron workpiece materials. The DIN 6535HA shank conforms to standard toolholder specifications for that shank diameter class. No specific machine model compatibility was provided by the manufacturer for this part.

Installation Notes

This drill bit should be installed by a qualified machinist or toolroom technician in a rigid, properly balanced toolholder. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify coolant-through pressure and flow rate are within the machine and tool specifications before starting a cut. Do not exceed the tool's rated depth-to-diameter ratio without consulting the manufacturer's feed and speed documentation.
