Guhring 9005150049800 Stub Drill Bit Size 9 0.196 in

Product Description

The GUHRING 9005150049800 is a stub-length (screw machine length) drill bit designed for high-productivity drilling in steel and cast iron. Built from powdered metal and finished with a multi-layer nano-FIREX coating, this bit handles demanding production environments where standard HSS tooling falls short. It carries a 130-degree point angle with cone relief geometry and a parabolic flute profile that promotes fast chip evacuation and reduced heat buildup. Overall length is 2.44 inches with a flute length of 1.02 inches. Licensed machinists, tool room techs, and CNC operators are the primary users of this tooling.

This drill bit is sized to wire gauge Number 9, equal to 0.1960 inches in decimal inch. The stub length format keeps the tool rigid and reduces deflection in short-hole applications. It is well-suited for CNC machining centers, drill presses, and screw machine operations where hole depth is limited to approximately 0.73 inches maximum and workpiece materials are steel or cast iron. The straight cylindrical shank at 0.1961 inches diameter fits standard collets and chucks without modification.

Key Features

• nano-FIREX multi-layer coating extends tool life in ferrous materials including steel and cast iron
• 130-degree cone relief point angle reduces thrust and improves self-centering on entry
• Parabolic fast-spiral flute design accelerates chip removal and reduces chip packing in blind holes
• Web-thinned construction lowers cutting resistance and decreases heat generation at the cutting edge
• Stub length format increases rigidity and minimizes runout compared to jobber-length equivalents
• Manufactured to DIN 1897 standard with h8 diameter tolerance for consistent fit in precision toolholding

Compatibility

Designed as a direct-fit stub-length drill for standard straight-shank collets, drill chucks, and toolholders accepting a 0.1961-inch shank diameter. Conforms to DIN 1897 specification. Primary workpiece materials are steel and cast iron.

Installation Notes

Installation and use of this tooling should be performed by qualified machinists or tool room personnel familiar with cutting tool safety. Ensure the machine spindle is fully stopped and locked out before loading or removing the bit from any chuck or collet. Verify chuck or collet bore matches the 0.1961-inch shank diameter before clamping to prevent runout or tool pullout. Do not exceed the maximum drilling depth of 0.73 inches without retracting to clear chips, particularly in blind-hole applications.
