Guhring 9003010009500 Cobalt Micro Drill Bit 0.0374 in

Product Description

The GUHRING 9003010009500 is a cobalt micro drill bit engineered for precision drilling in demanding industrial and machining applications. With a diameter of 0.0374 inches and an overall length of 0.984 inches, this bit is built for small-hole work where dimensional accuracy is critical. The 118-degree faceted point and web-thinned, tapered web configuration promote clean entry and reduced thrust force. The bright/uncoated cobalt construction provides heat resistance and edge retention across a wide range of workpiece materials. Machinists and toolroom professionals working with CNC equipment, drill presses, or precision hand tools rely on this Series 301 bit for repeatable, tight-tolerance results.

This micro drill bit is suited for drilling operations in both production and maintenance environments. It handles a broad material range including aluminum, aluminum alloy, brass, cast iron, hardened materials, nickel alloy, stainless steel, steel, and titanium alloy. The straight-cylindrical shank with a 1.5 mm shank diameter seats securely in standard collet chucks and drill press spindles. Right-hand spiral flute geometry supports efficient chip evacuation in through-hole and blind-hole applications at micro scale.

Key Features

• Cobalt tool material for elevated heat resistance and edge retention in hard and abrasive materials
• 118-degree faceted point with web thinning for reduced entry thrust and accurate hole start
• Tapered web configuration and regular spiral flute for reliable chip evacuation
• Bright/uncoated finish compatible with a wide range of cutting fluids and dry machining
• Straight-cylindrical shank at 1.5 mm diameter fits standard collet and chuck systems
• Manufactured to DIN 1899 specification for consistent dimensional standards

Compatibility

Designed for use with aluminum, aluminum alloy, brass, cast iron, hardened materials, nickel alloy, stainless steel, steel, and titanium alloy workpieces. Fits standard collet chucks and spindles accepting a 1.5 mm straight-cylindrical shank.

Installation Notes

Micro drill bits should be installed and operated by qualified machinists familiar with small-diameter tooling. Secure the shank fully in a precision collet or chuck before use and verify runout is within tolerance before beginning a cut. Due to the small diameter, use appropriate spindle speeds and feed rates for the workpiece material to avoid bit breakage. Always power down and lock out the machine spindle before changing tooling.
