Guhring 9005520100000 Drill Bit 10mm Hss Stub Length

Product Description

The GUHRING 9005520100000 is a stub-length (screw machine length) twist drill bit designed for high-performance metal removal in production and maintenance applications. Built to DIN 1897 standards from high speed steel with a bright, uncoated finish, it cuts a 10.00 mm (0.3937 inches) diameter hole with a 130-degree split point that reduces walking and thrust. The parabolic flute geometry promotes efficient chip evacuation, making this bit well suited for aluminum and other non-ferrous materials. A web-thinned, parallel-web construction reduces cutting resistance at entry. The straight-cylindrical shank seats securely in standard drill chucks and quick-change holders. This is a right-hand-cut tool intended for professional machinists, maintenance technicians, and metalworking tradespeople.

The 9005520100000 is a Series 552 stub-length drill engineered primarily for aluminum as the rated primary workpiece material. Its short overall length of 3.504 inches provides increased rigidity compared to jobber-length bits, reducing deflection in short-hole drilling operations on CNC machines, drill presses, and handheld equipment. The 1.693-inch flute length supports a maximum drilling depth of 1.102 inches, appropriate for through-holes and shallow blind holes in sheet stock, castings, and structural sections. The 3xD flute-to-diameter ratio keeps chips moving without clogging in ductile materials.

Key Features

• DIN 1897 stub-length standard for maximum rigidity in short-hole drilling
• 130-degree point angle reduces axial thrust and minimizes workpiece deformation on entry
• Parabolic flute geometry accelerates chip evacuation in aluminum and soft metals
• Web-thinned parallel web lowers cutting resistance and improves centering
• High speed steel construction withstands heat buildup in continuous production use
• Bright, uncoated finish allows easy visual wear inspection between uses

Compatibility

Designed as an OEM-style stub-length drill bit conforming to DIN 1897, compatible with standard straight-shank drill chucks and quick-change chuck systems sized for 10.00 mm shanks. Rated by the manufacturer for aluminum as the primary workpiece material.

Installation Notes

Install and remove this drill bit only with the machine fully de-energized and the spindle at a complete stop. Ensure the shank is fully seated in the chuck and the chuck is tightened with the proper key before operation. Always verify spindle speed is appropriate for the workpiece material and hole diameter before engaging the cut. Wear appropriate personal protective equipment, including eye protection and cut-resistant gloves, when handling or changing cutting tools.
