Guhring 9005490037300 Jobber Drill Bit Wire 26 Hss

Product Description

The GUHRING 9005490037300 is a jobber length drill bit in wire gauge size 26, measuring 0.1469 inches in diameter. Built from high speed steel with a bright uncoated finish, this bit is engineered to DIN 338 standards and carries a high performance grade designation. The 130-degree drill point angle and parabolic flute geometry work together to improve chip evacuation and reduce heat buildup during drilling. A web-thinned, tapered web configuration lowers entry resistance at the drill tip. Overall length is 2.75 inches with a 1.53-inch flute length and a straight-cylindrical shank. This is a right-hand cut, two-flute bit suited for production and general trade drilling applications.

This bit is rated primarily for aluminum and non-ferrous materials, reflecting its Series 549 high performance classification and parabolic flute design, which excels in softer, sticky materials that tend to pack chips. Typical applications include sheet metal fabrication, HVAC ductwork drilling, mechanical assembly, and maintenance work where small-diameter precision holes are required. The 5xD flute-to-diameter ratio supports deeper penetration relative to bit size. Maximum drilling depth is 1.315 inches. Installers and fabricators working in aluminum enclosures, electrical panels, or thin-wall tubing will find the geometry well matched to those materials.

Key Features

• Wire size 26 diameter at 0.1469 inches with a diameter tolerance of -0.018 to 0.000 mm for consistent hole sizing
• 130-degree split point reduces walking and lowers thrust force on entry
• Parabolic flute profile improves chip flow and reduces clogging in aluminum and non-ferrous cuts
• Web-thinned tapered web lowers cutting resistance at the tip
• Manufactured to DIN 338 specification, a recognized international standard for jobber length drill bits
• Bright uncoated finish — suitable for general purpose use without added coating wear concerns

Compatibility

Designed as a DIN 338 jobber length drill bit for use in standard drill chucks and drill presses accepting a 0.1469-inch straight-cylindrical shank. Primary workpiece material codes listed are K, N, and P, corresponding to aluminum, non-ferrous metals, and thermoplastics respectively.

Installation Notes

This bit is intended for use by machinists, fabricators, electricians, and HVAC technicians working with drill presses, hand drills, or CNC spindles. Secure the straight-cylindrical shank firmly in the chuck before operation and verify chuck capacity accommodates the 0.1469-inch shank diameter. Use appropriate cutting fluid or coolant when drilling aluminum to extend tool life, even though this bit does not support through-coolant delivery. Inspect the cutting edges for wear before each use and replace the bit if chipping or dulling is observed to maintain hole tolerance.
