Guhring 9024640017800 Carbide Drill Bit No 50 Firex

Product Description

The GUHRING 9024640017800 is a solid carbide jobber-length drill bit in wire gauge size No. 50 (0.0700 inches diameter), designed for precision drilling in aluminum and other non-ferrous materials. Built to Series 2464 standards per DIN specification, it features a FIREX coating for improved wear resistance and a faceted 118-degree drill point for accurate entry. The overall length is 1.81 inches (46 mm), with a 2-flute right-hand spiral flute configuration and a web-thinned tip that reduces thrust and improves chip evacuation. The straight-cylindrical shank measures 1.78 mm in diameter. This bit is suited for general-purpose production drilling by machinists and tool-and-die professionals working with small-diameter precision holes.

This drill bit is rated for primary use in aluminum (material code N) and is a solid carbide K40 grade tool, making it appropriate for high-speed drilling applications where consistency and dimensional accuracy are required. The 5xD flute-by-diameter ratio and 22 mm (0.87 inch) flute length support efficient chip removal at moderate drilling depths. Typical applications include CNC machining centers, drill presses, and bench-top precision drilling setups in job shops, aerospace fabrication, and electronics manufacturing environments where tight-tolerance small-diameter holes are needed.

Key Features

• Solid carbide K40 grade construction for rigidity and wear resistance in non-ferrous materials
• FIREX coating reduces friction and extends tool life in aluminum and similar workpiece materials
• Faceted 118-degree drill point with web-thinned tip reduces entry thrust and improves hole accuracy
• Right-hand, regular spiral, 2-flute geometry promotes efficient chip evacuation
• DIN-spec Series 2464 standard ensures consistent dimensional compliance
• Diameter tolerance of -0.012 to 0.000 mm supports tight-tolerance hole requirements

Compatibility

Designed as a general-purpose jobber-length drill bit for use in CNC machining centers, drill presses, and compatible toolholders accepting a 1.78 mm straight-cylindrical shank. Primary workpiece material rating is aluminum (material code N). No specific machine model compatibility was stated in the product data.

Installation Notes

Installation should be performed by a qualified machinist familiar with small-diameter carbide tooling. Secure the straight-cylindrical shank fully in a properly sized collet or chuck before operation to prevent runout. Carbide tooling is brittle and susceptible to chipping from side loads or improper fixturing — avoid using this bit in handheld drilling applications. Confirm spindle speed and feed rate are appropriate for the workpiece material and diameter before beginning the cut.
