Guhring 9005490019300 Jobber Drill Bit 48 Hss Din 338

Product Description

The GUHRING 9005490019300 is a jobber-length drill bit engineered for precision drilling in metalworking and general fabrication applications. Built from high-speed steel with a bright, uncoated finish, this bit features a parabolic flute geometry that improves chip evacuation and reduces heat buildup during drilling. It carries a 130-degree split point for accurate self-starting and reduced walking on entry. The overall length is 1-15/16 inches with a flute length of 15/16 inches, and the straight-cylindrical shank diameter measures 0.076 inches. Manufactured to DIN 338 standards, this is a high-performance Series 549 tool intended for use by machinists, tool-and-die professionals, and maintenance technicians who require consistent results at small diameters.

This drill bit is rated primarily for aluminum and non-ferrous materials, as indicated by workpiece material codes K, N, and P. It is well suited for light-duty precision work in production environments, maintenance and repair operations, and prototype or short-run machining. The parabolic flute design with web thinning makes it especially effective in gummy or stringy materials where chip packing is a concern. The 5xD flute-to-diameter ratio supports drilling depths up to 0.831 inches, which aligns with typical jobber-length applications in these material categories.

Key Features

• Wire gauge size 48 with a decimal diameter of 0.076 inches for tight-tolerance drilling
• Parabolic flute geometry promotes efficient chip removal and reduces heat at the cutting edge
• 130-degree standard point angle with web thinning for accurate entry and reduced thrust force
• High-speed steel construction rated for high-performance applications per DIN 338
• Straight-cylindrical shank fits standard drill chucks without special toolholding
• Bright, uncoated finish allows for easy visual inspection of wear and surface condition

Compatibility

Designed as a DIN 338-compliant jobber-length drill bit suitable for use in standard drill presses, CNC machining centers, and hand-held power tools accepting straight-cylindrical shanks in the 0.076-inch diameter range.

Installation Notes

This bit should be installed by a qualified machinist or maintenance technician familiar with small-diameter tooling. Ensure the spindle is fully stopped and power is locked out before changing tooling in any drill press or machining center. Use appropriate cutting fluid or mist coolant when drilling aluminum or non-ferrous metals to extend tool life, even though coolant-through is not available on this bit. Do not exceed the recommended drilling depth of 0.831 inches without retracting to clear chips.
