Guhring 9003010001500 Micro Drill Bit Size 97 Cobalt

Product Description

The GUHRING 9003010001500 is a cobalt micro drill bit designed for precision drilling in small-diameter applications. It carries a wire gauge size of 97, corresponding to a decimal diameter of 0.0059 inches, and features a 118-degree faceted point angle with web thinning for accurate entry without walking. The spiral flute geometry and right-hand cutting direction promote chip evacuation in tight bore conditions. With an overall length of 0.984 inches and a bright, uncoated finish, this bit is built for tight-tolerance work where dimensional accuracy and tool life both matter. It conforms to DIN 1899 specification and belongs to the GUHRING Series 301 micro drill line.

This micro drill bit is suited for precision drilling operations in aluminum, titanium alloy, and similarly machinable materials across light manufacturing, aerospace component work, and precision machining environments. The straight-cylindrical shank with a 1.00 mm diameter seats securely in collets and chucks sized for micro tooling. The 5xD flute-to-diameter ratio supports shallow drilling passes within a maximum drilling depth of 0.023 inches. Machinists and tool-and-die professionals working with close-tolerance bores will find this bit appropriate for production and prototype applications alike.

Key Features

• Wire gauge size 97 with 0.0059 inch decimal diameter for micro-bore applications
• 118-degree faceted point angle with web thinning for accurate, low-thrust entry
• Cobalt tool material provides heat and wear resistance in harder workpiece materials
• Spiral flute with tapered web configuration supports chip clearance in shallow holes
• Bright, uncoated finish compatible with a wide range of cutting fluids and dry cutting setups
• Conforms to DIN 1899 specification for standardized micro drill geometry

Compatibility

Designed as an OEM-style precision micro drill for use in standard collet chucks and drill spindles accepting a 1.00 mm straight-cylindrical shank. Primary workpiece materials are aluminum and titanium alloy as specified by the manufacturer.

Installation Notes

Installation and use of micro drill bits should be performed by qualified machinists familiar with CNC or manual drilling equipment sized for micro tooling. Ensure the spindle and collet are clean and free of debris before seating the shank to avoid runout. Operate within the machine manufacturer's recommended feed and speed parameters for the workpiece material and drill diameter. Inspect the cutting edges before each use, as micro drill bits are susceptible to edge chipping that may not be visible without magnification.
