Guhring 9003050045700 Cobalt Jobber Drill Bit Wire 15

Product Description

The GUHRING 9003050045700 is a cobalt jobber-length drill bit sized to wire gauge 15, equivalent to 0.1799 inches in diameter. It features a 118-degree standard point angle and a spiral flute with a right-hand cutting direction. The bit is oxide-coated for added surface hardness and heat resistance. Overall length is 80 millimeters with a flute length of 47 millimeters and a straight-cylindrical shank measuring 33 millimeters in length. The web is thinned and tapered for reduced thrust during entry. This is a general-purpose tool intended for use by machinists and maintenance trades working with ferrous materials.

This drill bit is suited for general-purpose drilling in cast iron and steel in both production and maintenance environments. The regular spiral and 5xD flute-to-diameter ratio support efficient chip evacuation in through-hole and shallow blind-hole applications. The straight-cylindrical shank seats directly in standard drill chucks without adapter hardware, making it compatible with bench drills, drill presses, and hand-held power drills used in fabrication shops, machine shops, and field maintenance settings.

Key Features

• Cobalt construction with oxide coating for improved heat resistance and extended tool life in ferrous materials
• 118-degree standard point angle with web thinning for reduced entry thrust
• Right-hand spiral flute with regular helix for efficient chip clearance
• Straight-cylindrical shank fits standard drill chucks without adapters
• Conforms to DIN 338 specification for consistent dimensional accuracy
• Diameter tolerance of -0.018 to 0.000 mm for controlled hole sizing

Compatibility

Designed for general-purpose drilling in cast iron and steel workpieces; primary workpiece material codes K and P per DIN classification.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with rotary cutting tools. Secure the shank fully in the drill chuck and confirm concentricity before operation. Do not exceed the recommended maximum drilling depth of 1.581 inches (40.15 millimeters) without retracting to clear chips. Eye protection and appropriate workholding are required when operating drill bits in any material.
