Guhring 9005520037300 Screw Machine Drill Bit Size 26 Hss

Product Description

The GUHRING 9005520037300 is a stub-length screw machine drill bit designed for high-speed steel cutting in demanding production and maintenance applications. Built to DIN 1897 standards, it features a 130-degree cone relief point and a parabolic flute geometry that promotes fast chip evacuation and reduced cutting resistance. The bright, uncoated HSS construction suits general-purpose drilling in steel, aluminum, and other non-ferrous materials. With a maximum drilling depth of 0.567 inches and a flute-to-diameter ratio of 3xD, this bit is optimized for short, precise holes where rigidity and accuracy matter. It belongs to the Guhring Series 552 high-performance line and is manufactured to tight diameter tolerances of +0.000 to -0.018 mm.

This drill bit is sized at wire gauge No. 26, corresponding to 0.1470 inches in decimal, and is suited for use in drill presses, CNC machining centers, and handheld power tools used in metal fabrication, HVAC sheet metal work, electrical panel assembly, and general industrial production. The straight cylindrical shank with a diameter of 0.1469 inches fits standard collets and chucks without modification. Its stub length and stiff web geometry make it a practical choice in tight-clearance setups where a jobber-length bit would flex or wander.

Key Features

• 130-degree cone relief point reduces thrust and improves self-centering on entry
• Parabolic fast-spiral flute geometry enhances chip evacuation in deep holes
• Web-thinned parallel web construction lowers cutting force and extends tool life
• Bright uncoated HSS finish — suitable for regrinding and compatible with cutting fluids
• DIN 1897 stub-length standard ensures consistent shank and flute dimensions
• Right-hand cut; compatible with standard drill press and CNC toolholding

Compatibility

Designed as a DIN 1897-compliant stub-length drill bit for use with standard straight-shank collets and drill chucks across drill press, handheld, and CNC applications in steel, aluminum, and non-ferrous workpiece materials.

Installation Notes

Installation and use should be performed by a qualified machinist or trade professional familiar with drill press or CNC setup procedures. Ensure the machine spindle is fully stopped and secured before inserting or removing the bit from the chuck or collet. Use appropriate cutting fluid or coolant when drilling steel to maintain edge life, even though this bit does not have internal coolant-through capability. Inspect the cutting edges for wear or chipping before each use and replace if the point shows signs of dulling to avoid workpiece damage or bit breakage.
