Guhring 9006530051600 Stub Drill Bit 13/64 Hss Tin

Product Description

The GUHRING 9006530051600 is a stub-length (screw machine length) twist drill bit designed for accurate, controlled drilling in metal fabrication and machining applications. Built from M2 high speed steel with a titanium nitride (TiN) coating, it offers improved wear resistance and longer tool life compared to uncoated HSS bits. The bit measures 13/64 inches (0.2031 inches) in diameter with a 2.4409-inch overall length and a 118-degree standard point angle. Web thinning reduces thrust force at the cutting tip, making entry cleaner on harder materials. Two spiral flutes channel chips out of the bore efficiently. This bit conforms to DIN 1897 standards and is suited for general-purpose production drilling work.

This stub-length drill bit is intended for use in drill presses, CNC machining centers, turret lathes, and hand-held power drills where a shorter, stiffer tool body is preferred over jobber-length bits. The reduced overall length minimizes deflection and improves hole location accuracy in repetitive or production drilling scenarios. Primary workpiece materials include cast iron and steel. The straight cylindrical shank fits standard drill chucks and collet holders sized for 0.2031-inch shank diameter. Machinists, tool-and-die tradespeople, and metalworking fabricators are the typical end users.

Key Features

• TiN coating increases surface hardness and reduces friction for extended tool life in steel and cast iron
• Stub (screw machine) length body at 2.4409 inches OAL provides greater rigidity and reduces bit deflection
• 118-degree standard point angle with web thinning for reduced entry thrust and cleaner hole start
• M2 high speed steel construction handles intermittent cuts and moderate feed rates without chipping
• Two spiral flutes with tapered web configuration promote consistent chip evacuation
• Meets DIN 1897 specification for dimensional accuracy and performance consistency

Compatibility

Designed as an OEM-style replacement or direct substitute for stub-length HSS drill bits conforming to DIN 1897 in 13/64-inch diameter. Compatible with standard drill chucks and collet systems accepting a 0.2031-inch straight cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists or metalworking tradespeople familiar with drill press and CNC equipment setup. Secure the shank fully within the chuck or collet and verify runout before drilling production parts. Always power down and lock out the machine before changing tooling. Do not exceed the recommended feed and speed parameters for the workpiece material and machine type.
