Guhring 9005490029500 No.32 Hss Jobber Drill 130 Deg

Product Description

The GUHRING 9005490029500 is a No. 32 wire-size jobber-length drill bit machined from high speed steel (HSS) to DIN 338 standards. It carries a 130-degree split point with web thinning for reduced thrust and faster penetration on entry, and a parabolic flute geometry that promotes efficient chip evacuation in deeper holes. The straight cylindrical shank measures 0.1161 inches in diameter, and the overall length is 2.4063 inches (2-13/32 inches). Designated as heavy-duty grade, this bit is built for production-level drilling in metalworking and fabrication environments where consistent hole quality is required.

This drill bit is suited for right-hand drilling in steel, cast iron, aluminum, and other non-ferrous materials. It is a common choice for machinists, tool-and-die technicians, maintenance engineers, and fabricators who need a reliable wire-gauge bit for tapped holes, close-tolerance bores, and general-purpose metal drilling. The parabolic flute design with a 5xD flute-by-diameter ratio makes it especially effective in setups where chip packing is a concern at moderate drilling depths.

Key Features

• No. 32 wire size with 0.1160 inch decimal diameter and a diameter tolerance of -0.014 to 0.000 mm for consistent hole sizing
• 130-degree standard point angle with web thinning reduces drill thrust and improves self-centering on entry
• Parabolic flute geometry with tapered web configuration promotes fast chip evacuation and reduced heat buildup
• High speed steel construction meets DIN 338 specification for heavy-duty grade performance
• Bright/uncoated finish suitable for use with cutting fluid on steel and non-ferrous workpieces
• Straight cylindrical shank compatible with standard drill chucks and collet systems

Compatibility

Designed as a DIN 338 Series 549 jobber drill for use in standard drill chucks and collet holders accepting a 0.1161-inch straight shank. Primary workpiece materials are steel, cast iron, aluminum, and non-ferrous alloys.

Installation Notes

Installation and use should be performed by a qualified machinist or skilled tradesperson familiar with drilling operations on metal workpieces. Secure the shank fully in a properly sized drill chuck or collet before operation, and verify chuck runout is within acceptable limits to preserve diameter tolerance. Apply appropriate cutting fluid for the workpiece material to extend tool life and maintain hole quality. Do not exceed the maximum drilling depth of 1.125 inches without a peck-drilling cycle to clear chips.
