Guhring 9085110033000 Carbide Jobber Drill 3.30 Mm

Product Description

The GUHRING 9085110033000 is a solid carbide jobber-length drill bit engineered for high-performance drilling in demanding materials. It features a 3.30 mm diameter, a 140-degree VA point angle, and a nano-A coating optimized for cutting titanium alloys and other difficult workpiece materials. The straight-cylindrical shank measures 6.00 mm in diameter and 36.00 mm in length. With a flute length of 28.00 mm and an overall length of 66.00 mm, this drill operates at a 5xD flute-to-diameter ratio. Web thinning is applied at the tip for self-centering entry, reducing thrust and improving hole accuracy on challenging substrates.

This drill is designed for precision machining applications where material hardness and work-hardening are primary concerns. Its nano-A coating delivers enhanced wear resistance and heat dissipation, making it well-suited for aerospace, medical, and specialty fabrication shops drilling titanium alloys and comparable high-strength materials. The coolant-through design supports internal coolant delivery at the cutting edge, extending tool life in production environments. It is installed and used by machinists and CNC operators working with drilling centers, machining centers, and drill presses requiring consistent hole tolerances.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• nano-A coating engineered for titanium alloys and high-strength workpiece materials
• 140-degree VA point angle with web thinning for self-centering, reduced thrust entry
• Coolant-through design supports internal coolant delivery at the cutting zone
• Straight-cylindrical shank at 6.00 mm diameter for standard collet and chuck compatibility
• Conforms to DIN 6535 and DIN 6537 L standards

Compatibility

Designed as a Series 8511 jobber drill per DIN specification, suited for use in machining centers, CNC drilling operations, and drill presses accepting a 6.00 mm straight-cylindrical shank. Primary workpiece material designation is titanium alloy (material code M and S).

Installation Notes

Installation and tool changes should be performed with the machine in a full stop, lockout state. Seat the straight-cylindrical shank fully and evenly in the collet or chuck before tightening to the tool holder manufacturer specification. Verify coolant-through passages are clear and that the coolant supply is active before beginning drilling cycles. Handling solid carbide tooling requires care to avoid edge chipping - do not drop or contact the cutting flutes against hard surfaces during setup.
