Guhring 9005490024400 No 41 Hss Jobber Drill Bit

Product Description

The GUHRING 9005490024400 is a No. 41 wire-size jobber-length drill bit machined from high speed steel (HSS) to DIN 338 standards. It carries a 130-degree split point geometry with web thinning for improved center-starting and reduced thrust in hard materials. The parabolic flute profile clears chips aggressively, making this bit well-suited for production drilling in steel, cast iron, aluminum, and other non-ferrous materials. The bright, uncoated finish means it is ready to run as received or can be re-coated by the end user. At 0.0960 inches in decimal diameter, it delivers consistent sizing within a -0.014 to 0.000 mm tolerance band. This is a trade-grade, heavy-duty bit intended for machinists, tool-room technicians, and maintenance mechanics.

The 9005490024400 targets production and maintenance drilling applications across metalworking environments. Its 0.0960-inch diameter is a standard wire-gauge size used in tapping operations, precision hole prep, and light fabrication work involving steel and non-ferrous stock. The parabolic flute design, combined with a tapered web and web-thinned point, reduces walking on entry and improves chip evacuation in through-hole and blind-hole scenarios. The straight cylindrical shank fits standard drill chucks and collets. With a 5xD flute-to-diameter ratio and a maximum recommended drilling depth of 1.037 inches, this bit is optimized for shallow-to-moderate depth holes at this diameter class.

Key Features

• No. 41 wire size — 0.0960 inch decimal diameter with -0.014 to 0.000 mm tolerance
• 130-degree standard point with web thinning for reduced entry thrust and improved self-centering
• Parabolic flute geometry promotes fast chip evacuation in steel, cast iron, and aluminum
• High speed steel construction — heavy-duty grade per DIN 338
• Bright uncoated finish — compatible with post-purchase coating processes
• Straight cylindrical shank fits standard chucks and collets without modification

Compatibility

Designed as an OEM-style tooling replacement for standard jobber drill applications conforming to DIN 338 specifications. Suitable for use in drill presses, CNC machining centers, and hand-held power drills equipped with a chuck accepting a 0.0961-inch straight shank. Primary workpiece materials include steel, cast iron, aluminum, and non-ferrous metals.

Installation Notes

Installation is performed by machinists or maintenance mechanics using a standard drill chuck or collet rated for the 0.0961-inch shank diameter. Secure the workpiece firmly before drilling to prevent movement and ensure hole accuracy. Verify spindle speed and feed rate are appropriate for the workpiece material and drill diameter before starting the cut. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed to maintain tolerance and surface quality.
