Guhring 9005150037300 Stub Drill Bit Size 26 0.147 in

Product Description

The GUHRING 9005150037300 is a screw machine length (stub) drill bit designed for precision drilling in steel and cast iron. Built from powdered metal and coated with a multi-layer nano-FIREX finish, it delivers extended tool life in demanding production environments. The bit features a 130-degree point angle with cone relief geometry and a parabolic flute profile for fast chip evacuation. At 2.0472 inches overall length and 0.1470 inch diameter (wire size 26), this compact stub-length drill is well suited for CNC and manual drilling operations where rigidity and accuracy are critical. Installation and operation are handled by machinists and tool-and-die professionals.

This drill bit is intended for use in ferrous materials, specifically steel and cast iron, in both production and job-shop environments. Its stub-length design minimizes deflection in short-reach drilling applications. The straight-cylindrical shank fits standard drill chucks across a wide range of benchtop drill presses, CNC machining centers, and screw machines. The parabolic flute geometry and 3xD flute-to-diameter ratio support efficient chip clearing at higher feed rates common in automated or high-cycle operations.

Key Features

• Powdered metal construction with multi-layer nano-FIREX coating for extended wear resistance in ferrous materials
• 130-degree cone relief point angle optimized for drilling into steel and cast iron
• Parabolic fast-spiral flute design promotes rapid chip evacuation and reduces heat buildup
• Stub length (2.0472 inches OAL) provides superior rigidity and reduced deflection versus jobber-length bits
• Straight-cylindrical shank with h8 diameter tolerance ensures accurate chuck fitment
• Web-thinned geometry reduces thrust force at entry, improving hole quality
• Conforms to DIN 1897 standard, Series 515

Compatibility

Designed as an OEM-style stub drill for use in standard drill chucks and collet systems accepting a 0.1469-inch straight-cylindrical shank. Primary workpiece materials are steel and cast iron.

Installation Notes

This drill bit is installed and operated by machinists, toolroom technicians, and production drilling personnel. Ensure the drill press or machining center spindle is fully stopped and locked out before changing tooling. Secure the straight shank firmly in the chuck or collet to the appropriate holding depth before initiating a cut. Do not exceed the maximum recommended drilling depth of 0.5670 inches per pass without retracting to clear chips.
