Guhring 9006520070000 Jobber Drill Bit 7mm Hss Tin

Product Description

The GUHRING 9006520070000 is a jobber-length twist drill bit designed for high-performance metal drilling applications. Built from high-speed steel (HSS) with a titanium nitride (TiN) coating, this bit delivers extended tool life and reduced friction at the cutting edge. It measures 7 mm (0.2756 inches) in diameter with an overall length of 4-9/32 inches. The 130-degree point angle and parabolic flute geometry support aggressive chip evacuation, making this bit well suited for production and repetitive drilling work. A web-thinned, tapered web reduces entry resistance and helps maintain accurate hole positioning from the start of the cut.

This drill bit is rated as a high-performance Series 652 tool manufactured to DIN 338 standards. Its primary workpiece material designation covers aluminum and non-ferrous metals (K), non-metals (N), and long-chipping steels (P), making it a practical choice for shops drilling mixed-material workpieces. It is sold individually and is appropriate for use in drill presses, CNC machining centers, and hand-held electric drills where a straight-cylindrical shank is accepted. Licensed machinists, toolroom technicians, and maintenance mechanics are the typical end users.

Key Features

• TiN coating reduces friction and extends cutting edge life compared to uncoated HSS bits
• Parabolic flute geometry accelerates chip removal and lowers heat buildup in the cut
• 130-degree split-point angle with web thinning reduces walking and entry force
• Tapered web construction adds core strength while keeping the point geometry aggressive
• Straight-cylindrical shank fits standard drill chucks without adapters
• Manufactured to DIN 338 specification for consistent dimensional tolerances

Compatibility

Designed as a DIN 338 jobber-length drill bit for use in standard drill chucks accepting a 0.2756-inch straight-cylindrical shank. Primary workpiece material codes K, N, and P indicate suitability for aluminum, non-ferrous metals, non-metals, and general-purpose steels.

Installation Notes

This bit is installed by machinists and maintenance technicians in drill presses, mills, or hand-held electric drills. Secure the shank fully in the chuck and verify concentricity before starting the cut. Ensure the workpiece is clamped or fixtured to prevent rotation. This bit does not support coolant-through delivery; apply cutting fluid externally when drilling steel or harder alloys to manage heat and prolong tool life.
