Guhring 9065090040000 Extra Length Carbide Drill Bit

Product Description

The GUHRING 9065090040000 is a solid carbide extra length drill bit engineered for deep hole drilling applications in demanding industrial and metalworking environments. Part of the Series 6509 lineup, this bit features a TiAlN coating, a 135-degree drill point angle, and a spiral flute design that promotes efficient chip evacuation at extended depths. The RT100 T point geometry combined with web thinning reduces entry force and improves centering accuracy. With a flute-to-diameter ratio of 15xD and coolant-through capability, it is built for high-performance production drilling where standard-length tooling falls short. Machinists and toolroom technicians working on precision components will find this bit well-suited to their requirements.

This drill bit is intended for use in CNC machining centers, drill presses, and other machine tool setups requiring extended reach. It is rated for primary use in cast iron, stainless steel, and steel, with secondary suitability for aluminum and titanium alloys. The straight-cylindrical shank with a 6.00 mm shank diameter provides consistent tool holding in standard collet chucks and hydraulic tool holders. The right-hand cutting direction and 2-flute configuration are standard for most deep hole drilling operations in metal fabrication and precision manufacturing shops.

Key Features

• TiAlN coating improves heat resistance and tool life in ferrous and high-strength materials
• RT100 T point geometry with web thinning reduces thrust and improves hole entry accuracy
• Coolant-through design supports deep hole drilling up to 70.00 mm (2.756 inches) maximum depth
• 15xD flute-to-diameter ratio enables extended reach beyond standard drill bit capability
• Diameter tolerance of h7 ensures consistent fit in precision tooling setups
• Right-hand spiral flute promotes reliable chip evacuation in long-reach applications

Compatibility

Designed as an OEM-style production drill for use in machine tool setups compatible with straight-cylindrical shank tooling; primary workpiece materials include cast iron, stainless steel, and steel, with secondary compatibility for aluminum and titanium alloys.

Installation Notes

Installation and operation of this tooling should be performed by qualified machinists or toolroom technicians familiar with CNC or manual drilling equipment. Before changing or setting tooling, ensure the machine spindle is fully stopped and the machine is placed in a safe, locked-out state per applicable shop safety procedures. Verify that the tool holder bore is clean and undamaged before seating the straight-cylindrical shank. Coolant-through setups require that coolant lines and pressure are confirmed before initiating the drilling cycle to prevent premature tool wear.
