Guhring 9002050038000 No. 25 Hss Jobber Drill Bit

Product Description

The GUHRING 9002050038000 is a high speed steel jobber-length drill bit in No. 25 wire gauge size, equivalent to 0.1496 inches in diameter. It features a standard 118-degree split point with web thinning for reduced thrust and cleaner entry, and an oxide coating that provides light lubricity and corrosion resistance during drilling. The spiral flute geometry is a regular right-hand configuration designed for general-purpose hole-making in a wide range of metallic materials. The overall length is 2.953 inches (75 millimeters), with a flute length of 1.693 inches (43 millimeters) and a maximum drilling depth of 1.469 inches. This drill is manufactured to DIN 338 standards and is suited for use by machinists, maintenance technicians, and tool-room professionals.

This bit is intended for drilling cast iron and steel in both production and maintenance environments. The straight-cylindrical shank with a diameter of 0.1496 inches fits standard three-jaw drill chucks found on drill presses, CNC machining centers, and hand drills. The Series 205 designation places it within a general-purpose product line appropriate for everyday metalworking tasks at moderate speeds and feeds. The tapered web configuration helps maintain rigidity while keeping the cutting geometry efficient across typical shop conditions.

Installation Notes

Install in a properly tightened three-jaw chuck before powering the machine. Secure the workpiece firmly to prevent movement during drilling. Apply cutting fluid appropriate for the workpiece material to extend tool life and improve hole finish. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point geometry is compromised.
