Guhring 9006520061500 Jobber Drill Bit Letter C Hss Tin

Product Description

The GUHRING 9006520061500 is a jobber-length drill bit sized to Letter C (0.2421 inches) for use in metal fabrication, machining, and general production drilling. Built from high speed steel with a titanium nitride (TiN) coating, this bit delivers extended cutting life and reduced friction compared to uncoated HSS tooling. The 130-degree drill point angle improves centering and reduces thrust, making it well suited for harder or abrasive workpieces. A parabolic flute geometry promotes fast chip evacuation, which is critical when drilling deeper holes. Overall length is 3-31/32 inches with a straight-cylindrical shank at 0.2421 inches in diameter. The web-thinned, tapered web design reduces cutting resistance at the point. Conforms to DIN 338.

This drill bit is rated as a high-performance tool with a primary workpiece designation for aluminum (material codes K, N, and P), making it appropriate for production environments drilling non-ferrous metals and similar materials. The 5xD flute-to-diameter ratio and a maximum drilling depth of 2.117 inches support deeper hole applications in a standard jobber-length format. It is sold individually and sized for use in standard drill chucks, CNC machining centers, drill presses, and handheld power drills wherever a straight-cylindrical shank is accepted. Series 652 from Guhring is designed for high-output shop environments where consistent dimensional accuracy is required.

Key Features

• Letter C size: 0.2421 inches decimal equivalent for precise sizing reference
• TiN coating reduces friction and extends tool life compared to bare HSS
• 130-degree split point angle improves self-centering and lowers thrust force
• Parabolic flute design accelerates chip evacuation in deeper cuts
• Web-thinned tapered web reduces cutting resistance at the drill point
• Conforms to DIN 338 standard for jobber-length drill geometry

Compatibility

Designed as a DIN 338 jobber-length drill bit for use in standard straight-cylindrical shank drill chucks. Primary workpiece material designation is aluminum and similar non-ferrous materials (material codes K, N, P). Accepts any drill chuck or collet sized for a 0.2421-inch straight shank.

Installation Notes

Installation of this drill bit is performed by machining professionals, tool-and-die tradespeople, or experienced metalworkers. Secure the shank fully into the drill chuck or collet and verify runout before beginning a cut. Always match spindle speed and feed rate to the workpiece material and bit diameter per standard machining tables. Wear appropriate eye protection and secure the workpiece before drilling.
