Guhring 9024630018500 Screw Machine Drill Bit 0.073in

Product Description

The GUHRING 9024630018500 is a screw machine length (stub) solid carbide drill bit designed for precision drilling in high-demand trade and industrial applications. Built to DIN 6539 standards with a K40 carbide grade, this bit measures 0.073 inches (wire size #49) in diameter with an overall length of 1.417 inches and a flute length of 0.433 inches. The 118-degree faceted point and web-thinned geometry reduce entry force and improve hole location accuracy. With a maximum drilling depth of 0.324 inches and a 3xD flute-to-diameter ratio, it is suited for controlled, shallow-hole operations. Licensed machinists, tool and die technicians, and precision fabricators are the primary installers.

This bit is engineered for general-purpose drilling with a primary workpiece material designation of aluminum, though its solid carbide construction and coated finish make it capable across a range of non-ferrous and soft ferrous materials. The stub-length body provides rigidity in CNC machining centers, drill presses, and screw machine setups where reduced overhang and tight tolerances matter. The straight-cylindrical shank fits standard collet chucks and drill chucks used in production and prototype environments. Series 2463 is Guhring's stub-length carbide drill line built to DIN specification for consistent dimensional performance.

Key Features

• Solid carbide K40 grade construction for wear resistance and dimensional stability
• 118-degree faceted drill point with web thinning for reduced thrust and accurate entry
• DIN 6539 standard compliance for consistent tolerance and interchangeability
• Diameter tolerance of +0.000 to -0.010 mm for precise fit requirements
• Right-hand cut, 2-flute regular spiral design for efficient chip evacuation
• Coated finish to extend tool life in repetitive drilling cycles

Compatibility

Designed as an OEM-style screw machine length drill bit conforming to DIN 6539 specifications, suitable for use in standard collet chucks and drill chucks accepting a 1.85 mm straight-cylindrical shank.

Installation Notes

This drill bit is installed and operated by machinists and tooling technicians in machine shop environments. Ensure the spindle and workholding are fully stopped and secured before changing tooling. Verify collet or chuck runout is within acceptable tolerance before operation, as carbide is brittle and sensitive to lateral loading. Do not exceed the maximum drilling depth of 0.324 inches per pass without retracting to clear chips.
