Guhring 9065090095200 Extra Length Drill Bit 0.375 in

Product Description

The GUHRING 9065090095200 is a solid carbide extra length drill bit engineered for deep hole drilling applications in demanding materials. Built on the Series 6509 platform with a RT100 T point geometry and 135-degree drill point angle, this bit delivers consistent performance in cast iron, stainless steel, and steel. The TiAlN coating provides thermal resistance and extended tool life under high-speed cutting conditions. At 0.375 inches (3/8 inch) diameter with an overall length of approximately 8.70 inches, this bit targets production and maintenance environments where standard-length tooling cannot reach. Coolant-through capability supports chip evacuation in deep hole operations.

This drill bit is suited for deep hole drilling in ferrous and high-strength materials across industrial machining, maintenance, and fabrication environments. The 15xD flute-to-diameter ratio and spiral flute design support controlled chip removal during extended-depth passes. Secondary workpiece material compatibility includes aluminum and titanium alloy. The straight-cylindrical shank with h7 diameter tolerance ensures accurate seating in standard drill chucks and collet systems. Typical users include machinist tradespeople operating CNC machining centers, drill presses, and manual mills in production or job-shop settings.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive workpiece materials
• TiAlN coating provides high-temperature resistance and reduced built-up edge during cutting
• Coolant-through design supports chip flushing and tool cooling in deep hole drilling cycles
• RT100 T point geometry with web thinning reduces entry force and improves centering accuracy
• 135-degree drill point angle suited for self-starting entry on flat and curved surfaces
• 15xD flute-to-diameter ratio enables drilling depths up to approximately 6.41 inches in a single operation

Compatibility

Designed for use with cast iron, stainless steel, and steel as primary workpiece materials, with secondary compatibility for aluminum and titanium alloy. The straight-cylindrical shank with h7 tolerance fits standard drill chucks and collet holders accepting a 10 mm shank diameter.

Installation Notes

Installation and use should be performed by qualified machinist personnel following shop safety procedures. Ensure the machine spindle is fully stopped and the workpiece is securely clamped before tool changes. Verify coolant-through supply pressure and flow rate match the machine tool specifications before initiating deep hole drilling cycles. Do not exceed the maximum drilling depth of 6.41 inches in a single pass without confirming chip evacuation is effective.
