Guhring 9006520067000 Jobber Drill 6.70mm Hss Tin Series 652

Product Description

The GUHRING 9006520067000 is a high speed steel (HSS) jobber-length drill bit with a titanium nitride (TiN) coating, designed for production and maintenance drilling in steel, cast iron, aluminum, and non-ferrous materials. The drill features a 130-degree point angle with web thinning and a tapered web configuration for improved centering and reduced thrust at entry. The parabolic flute geometry promotes efficient chip evacuation in deeper holes. The overall length is 3.9688 inches and the flute length is 2.4688 inches, with a straight cylindrical shank measuring 0.2638 inches in diameter. This bit is built to DIN 338 standards and is classified as a heavy-duty grade, making it suited for production machinists, tool-and-die shops, and maintenance professionals working with mixed-material applications.

This drill bit is intended for right-hand cutting operations on drilling machines, CNC machining centers, and manual drill presses. Primary workpiece materials include steel, cast iron, aluminum, and other non-ferrous metals. The Series 652 parabolic flute design supports a maximum drilling depth of 2.09 inches, which corresponds to the 5xD flute-to-diameter ratio. It is packaged individually and sold in single-piece quantities, making it practical for spot replacements or tooling builds where a single specific diameter is needed.

Key Features

• HSS construction with TiN coating for extended tool life in ferrous and non-ferrous drilling
• 130-degree point angle with web-thinned, tapered web for reduced entry thrust and improved self-centering
• Parabolic flute geometry supports efficient chip evacuation up to 2.09 inches depth
• Straight cylindrical shank fits standard drill chucks without adapters
• Manufactured to DIN 338 specification, heavy-duty grade
• Right-hand cutting direction, 2-flute design

Compatibility

Designed as a DIN 338-compliant jobber drill for use in standard drill chucks and collet systems that accept a 0.2638-inch straight shank. Suitable for drilling steel, cast iron, aluminum, and non-ferrous materials across Series 652 tooling setups.

Installation Notes

Installation is performed by machinists or maintenance technicians using standard three-jaw or keyless drill chucks. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify chuck capacity matches the 0.2638-inch shank diameter before seating the bit. No coolant-through capability is present on this drill; apply external cutting fluid or mist coolant as appropriate for the workpiece material and depth of cut.
