Guhring 9003050015000 Cobalt Jobber Drill Bit 1.50 Mm

Product Description

The GUHRING 9003050015000 is a cobalt jobber-length drill bit designed for general-purpose drilling in ferrous materials. Built to DIN 338 standards, it features a 1.50 mm diameter, a 118-degree cone relief point, and a bright uncoated finish. The two-flute spiral design with web thinning reduces thrust and improves chip evacuation at entry. With an overall length of 40.00 mm and a flute length of 18.00 mm, this bit is suited for precision drilling applications where tight tolerances are required. The h8 diameter tolerance ensures consistent fit in standard collets and chucks. Machinists, tool-and-die workers, and maintenance technicians are the primary users of this bit.

This drill bit is intended for use in ferrous materials including cast iron and steel, covering primary workpiece material codes K and P. It is well-suited for CNC machining centers, drill presses, and hand-held drilling equipment in both production and maintenance environments. The straight-cylindrical shank accommodates standard drill chucks without the need for specialized toolholding. The 5xD flute-to-diameter ratio supports drilling depths up to 15.75 mm, making it appropriate for through-holes and moderate-depth blind holes in light industrial and fabrication settings.

Key Features

• Cobalt construction for improved heat resistance and tool life in ferrous materials
• 118-degree cone relief point for clean entry and reduced walking on flat surfaces
• Web-thinned geometry reduces axial thrust during drilling
• h8 diameter tolerance for consistent chuck and collet fit
• Regular spiral, right-hand cutting direction for standard drill setups
• DIN 338 compliant, Series 305 construction

Compatibility

Designed as an OEM-style general-purpose jobber drill for use in standard drill chucks and collet systems accepting a 1.50 mm straight-cylindrical shank. Rated for cast iron and steel workpiece materials per primary workpiece material codes K and P.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tooling technicians familiar with cutting tool setup. Ensure the drill chuck or collet is properly tightened and the workpiece is securely fixtured before operation. Coolant-through is not supported on this bit, so external coolant or cutting fluid should be applied as appropriate for the workpiece material. Inspect the cutting edges for wear or chipping before each use and replace the bit if edge integrity is compromised.
