Guhring 9003050039100 Cobalt Jobber Drill Bit Wire 23

Product Description

The GUHRING 9003050039100 is a cobalt jobber-length drill bit sized to wire gauge number 23, equivalent to 0.1539 inches in diameter. Built to DIN 338 standards, it features a 118-degree standard point angle and an oxide coating for improved heat resistance and surface hardness. The overall length is 75 millimeters, with a 43-millimeter flute length and a straight-cylindrical shank. The web-thinned, tapered web design reduces thrust at entry and improves chip evacuation. This bit is intended for use by machinists, maintenance technicians, and metalworking tradespeople working with steel and cast iron.

This drill bit is suited for general-purpose metalworking applications in both production and maintenance settings. It performs well in ferrous materials including cast iron and steel, designated under material codes K and P. The right-hand spiral flute configuration handles standard drilling operations in these materials without requiring coolant-through capability. It is a solid choice for light-to-medium duty bench drilling, drill press work, or hand-held drilling where precision hole sizing to wire gauge 23 is required.

Key Features

• Cobalt construction with oxide coating for improved heat and wear resistance
• 118-degree standard point angle with web thinning for reduced entry thrust
• DIN 338 specification for consistent dimensional accuracy
• Right-hand cut with regular spiral flute for reliable chip clearance
• Straight-cylindrical shank compatible with standard drill chucks
• Maximum drilling depth of 1.462 inches (37.14 millimeters)

Compatibility

Designed as a general-purpose jobber-length drill bit for use in standard drill chucks accepting a 0.1539-inch straight-cylindrical shank. Primary workpiece materials are cast iron and steel per DIN 338 material codes K and P.

Installation Notes

Installation and use of this bit should be performed by a qualified machinist or tradesperson familiar with metal drilling operations. Secure the workpiece firmly before drilling and ensure the drill chuck is fully tightened on the straight shank. Power down all equipment before changing bits. Do not exceed the recommended drilling depth of 1.462 inches for this bit length.
