Guhring 9006520066300 Drill Bit Letter G 0.261 in Hss Tin

Product Description

The GUHRING 9006520066300 is a jobber length drill bit sized to letter G (0.2610 inches decimal) and built for high-performance metal cutting in trade and industrial applications. The bit is manufactured from high speed steel with a titanium nitride (TiN) coating that extends tool life by reducing surface friction and heat buildup at the cutting edge. It features a 130-degree split point for fast, accurate starts without a center punch, a parabolic flute geometry that clears chips aggressively, and a web-thinned tip that reduces thrust requirements. Overall length is 3-31/32 inches with a 2-15/32 inch flute length and a straight-cylindrical shank measuring 0.2610 inches in diameter. This bit is intended for machinists, tool-and-die tradespeople, and maintenance technicians running production or repair drilling operations.

The 9006520066300 is well-suited for drilling aluminum and other non-ferrous metals as well as general-purpose steel applications where the parabolic flute geometry aids chip evacuation in deeper holes. It conforms to DIN 338 standards and belongs to GUHRING Series 652, a high-performance jobber-length line designed for consistent diameter tolerance and repeatable hole quality. Typical install scenarios include CNC machining centers, drill presses, and hand-held electric drills used in fabrication, HVAC sheet metal work, and mechanical maintenance. Maximum drilling depth is 2.0890 inches (53.06 mm).

Key Features

• Letter G size — 0.2610 inch decimal diameter with tolerance of -0.022 to 0.000 mm for tight hole consistency
• Titanium nitride (TiN) coating reduces friction and extends cutting life compared to uncoated HSS
• Parabolic flute geometry with 5xD flute-to-diameter ratio promotes fast chip evacuation in deep holes
• 130-degree standard point angle with web thinning lowers entry thrust and improves centering
• Straight-cylindrical shank fits standard drill chucks without a reducer or adapter
• DIN 338 compliant — meets recognized dimensional and performance standards for jobber-length drills

Compatibility

Designed as a DIN 338 jobber-length replacement or production drill bit for use in standard drill chucks accepting a 0.2610 inch straight-cylindrical shank. Primary workpiece material codes K, N, and P indicate suitability for aluminum, non-ferrous metals, and general steel. No specific machine or system compatibility was provided in the product data.

Installation Notes

Installation and use should follow standard machinist safety practices — secure the workpiece firmly before drilling and confirm the chuck is fully tightened to prevent bit slippage. Power down and de-energize any drill press or machine before changing bits. Cutting fluid or coolant is recommended for steel applications even though this bit does not have through-coolant capability. Dispose of worn bits according to local shop safety protocols, as TiN-coated HSS tooling has sharp edges and metal debris hazards.
