Guhring 9005490027100 Jobber Drill No. 36 Hss 130 Deg

Product Description

The GUHRING 9005490027100 is a high speed steel jobber-length drill bit sized to No. 36 wire gauge (0.1065 inch decimal equivalent). Built to DIN 338 standards, this bit features a 130-degree split point with web thinning for fast, accurate engagement on harder materials. The parabolic flute geometry improves chip evacuation and reduces heat buildup during drilling. With a straight cylindrical shank and a bright, uncoated finish, it is a heavy-duty general-purpose drill suited for machine shop, MRO, and production drilling applications. Licensed machinists, maintenance mechanics, and metalworking professionals are the primary users.

This jobber drill is designed for drilling into steel, cast iron, aluminum, and other non-ferrous metals. The 5xD flute-to-diameter ratio provides sufficient chip clearance for the material types common in production and maintenance environments. The Series 549 designation indicates a heavy-duty grade appropriate for demanding drilling cycles. Its compact overall length of 2.4063 inches (2-13/32 inches) makes it practical for use in confined areas or in drill presses and CNC machining centers where tool clearance matters.

Key Features

• No. 36 wire size, 0.1065 inch decimal diameter for precision hole sizing
• 130-degree point angle with web thinning reduces thrust and self-centers on entry
• Parabolic flute design promotes efficient chip removal in steel and non-ferrous metals
• Manufactured to DIN 338 specification for consistent dimensional tolerances
• Straight cylindrical shank compatible with standard drill chucks and collet holders
• Bright uncoated finish — suitable for general-purpose metal drilling without coolant-through requirements

Compatibility

Designed as an OEM-style jobber drill for use in standard drill chucks, collet systems, and CNC tool holders accepting straight-shank bits in the 0.1065 inch diameter range. Primary workpiece materials include steel, cast iron, aluminum, and non-ferrous alloys.

Installation Notes

Installation and use of drill bits of this type falls within the scope of qualified machinists or maintenance mechanics familiar with drill press, hand drill, or CNC machining operations. Secure the shank fully in the chuck or collet before operation and verify runout before high-cycle use. Follow machine manufacturer speed and feed recommendations for the specific workpiece material; do not exceed rated spindle speeds for the bit diameter. Inspect the cutting edges before each use and replace worn bits promptly to avoid oversize holes or workpiece damage.
