Guhring 9005490100000 Jobber Drill 10mm Hss

Product Description

The GUHRING 9005490100000 is a high-speed steel jobber-length drill bit engineered for precision hole-making in metalworking and industrial fabrication applications. Built to DIN 338 standards, this Series 549 drill features a 130-degree split point geometry and a parabolic flute design that improves chip evacuation and reduces cutting resistance. The bit measures 10.00 mm (0.3937 inches) in diameter with an overall length of 133.00 mm (5-15/64 inches) and a flute length of 87.00 mm (3-27/64 inches). The bright, uncoated finish is typical of high-performance HSS tooling where coating compatibility or regrinding is a factor. This is a right-hand cutting tool with a straight-cylindrical shank suited for standard drill chucks.

This drill is designed primarily for aluminum and similar non-ferrous and general-purpose materials, consistent with its K, N, and P workpiece material classifications. It suits production drilling in CNC machining centers, drill presses, and handheld power tools where a straight shank is appropriate. With a maximum recommended drilling depth of 72.00 mm (2.835 inches) and a 5xD flute-to-diameter ratio, it is well-matched to through-hole and moderate-depth blind-hole operations. Machinists, tool-and-die shops, and metalworking trades use this bit for consistent, repeatable performance across standard drilling cycles.

Key Features

• 10.00 mm diameter with tight tolerance of -0.022 to 0.000 mm for precise hole sizing
• 130-degree point angle with web-thinned, tapered web for reduced thrust and clean entry
• Parabolic flute geometry promotes efficient chip removal and reduced heat buildup
• Built to DIN 338 specification for consistent dimensional and performance standards
• Straight-cylindrical shank fits standard 3-jaw drill chucks without adapters
• Bright/uncoated finish allows easy regrinding and is compatible with cutting fluids

Compatibility

Designed as a DIN 338-compliant jobber drill for use in standard drill chucks accepting a 0.3937-inch straight-cylindrical shank. Primary workpiece material classifications are K (cast materials), N (non-ferrous metals), and P (general steels) as designated in the supplier specifications.

Installation Notes

Installation is performed by machinists or qualified machine operators. Secure the shank fully in the drill chuck and verify runout before beginning a drilling cycle. Apply appropriate cutting fluid or coolant for the workpiece material to extend tool life, even though this bit does not feature through-coolant capability. Follow shop safety protocols and machine manufacturer guidelines for speed and feed selection based on workpiece material and depth of cut.
