Guhring 9006510059500 Jobber Drill Bit 15/64 Hss Tin

Product Description

The GUHRING 9006510059500 is a jobber length drill bit designed for general-purpose drilling in metal fabrication, mechanical, and maintenance trade applications. Built from M2 high speed steel with a titanium nitride (TiN) coating, it delivers improved surface hardness and wear resistance compared to uncoated HSS tooling. The bit measures 0.2344 inches (15/64 inch) in diameter with an overall length of 3.6614 inches and a usable flute length of 2.2441 inches. The 118-degree standard point angle suits most common drilling operations in steel and cast iron. A right-hand, regular spiral flute geometry provides efficient chip evacuation, while the web-thinned, tapered web reduces entry resistance and improves centering accuracy.

This drill bit is suited for machine shop, maintenance, and field-service use where consistent hole quality in ferrous materials is required. It performs in production drilling of cast iron and steel workpieces in both handheld and machine-mounted setups. The straight cylindrical shank accepts standard drill chucks across a wide range of drill presses, lathes, and hand drills. With a 5xD flute-to-diameter ratio and DIN 338 conformance, it fits professional toolrooms and trade service vans equally well. Sold individually.

Key Features

• M2 high speed steel construction provides toughness and heat resistance for ferrous drilling
• Titanium nitride (TiN) coating increases surface hardness and extends service life versus uncoated HSS
• 118-degree standard point angle for general-purpose entry into steel and cast iron
• Web-thinned, tapered web reduces thrust force and improves self-centering
• Right-hand, regular spiral flute promotes clean chip evacuation
• Conforms to DIN 338 specification for consistent dimensional tolerances

Compatibility

Designed as a general-purpose jobber length drill bit compatible with any standard drill chuck accepting a 0.2344-inch straight cylindrical shank. Primary workpiece materials are steel and cast iron per DIN 338 Series 651 specification.

Installation Notes

Install in a properly sized drill chuck and tighten securely before operation. Ensure the workpiece is clamped or fixtured to prevent rotation during drilling. Use appropriate cutting fluid or coolant when drilling steel to manage heat buildup, noting this bit does not support through-coolant delivery. Inspect the cutting edge for wear or chipping before each use and replace if edge integrity is compromised.
