Guhring 9065110095200 Extra Length Carbide Drill Bit 3/8

Product Description

The GUHRING 9065110095200 is a solid carbide extra length drill bit designed for deep hole drilling applications in demanding production environments. Built to Series 6511 specifications, it features a TiAlN coating, a 135-degree split point, and a web-thinned tapered web configuration that reduces entry force and improves chip evacuation. The 3/8-inch (0.3750 inches) diameter bit has an overall length of 271 millimeters and a flute length of 227 millimeters, providing a 20xD flute-to-diameter ratio suited to extended reach work. Internal coolant-through capability supports high-speed metal removal while managing heat at the cutting zone. Right-hand spiral flutes with a standard point geometry complete the design. Licensed machinists, toolroom technicians, and CNC operators are the primary installers.

This drill bit is engineered for deep hole drilling in cast iron, stainless steel, and carbon steel as primary workpiece materials. Secondary workpiece material compatibility includes aluminum and titanium alloy. The extended reach and coolant-through design make it well matched to CNC machining centers, drill presses, and transfer machines where hole depths exceed standard drill capability. The straight-cylindrical shank with a 10-millimeter shank diameter and 40-millimeter shank length fits standard collets and drill chucks within that size range.

Key Features

• Solid carbide submicron-grade construction for rigidity and edge retention in hard and abrasive materials
• TiAlN coating improves heat resistance and extends tool life at elevated cutting speeds
• Coolant-through design channels coolant directly to the cutting zone for deep hole applications
• 135-degree split point with web thinning reduces thrust force and improves centering accuracy
• 20xD flute-to-diameter ratio enables drilling depths up to approximately 261 millimeters
• Right-hand spiral flutes with tapered web configuration promote consistent chip flow in through-hole and blind-hole work

Compatibility

Designed for use in CNC machining centers, drill presses, and similar machine tools accepting a straight-cylindrical shank with a 10-millimeter shank diameter. Primary workpiece materials include cast iron, stainless steel, and steel. Secondary workpiece materials include aluminum and titanium alloy.

Installation Notes

Installation and operation should be performed by qualified machinists or CNC tooling technicians. Secure the straight-cylindrical shank firmly in a matched collet or drill chuck before operation and verify runout is within acceptable tolerance for the application. Confirm coolant-through supply is connected and at adequate pressure before initiating the cut. Do not exceed the rated maximum drilling depth of approximately 261 millimeters in a single pass without a verified pecking or chip-clearing cycle.
