Guhring 9024640073000 Carbide Drill Bit 7.3 Mm Firex

Product Description

The GUHRING 9024640073000 is a solid carbide jobber-length drill bit designed for precision drilling in demanding production and machining environments. Built to DIN specification from K40 carbide grade, it features a FIREX coating that extends tool life and reduces friction during cutting. The 118-degree faceted point geometry enables clean entry and consistent hole placement. At 7.3 mm in diameter with a 109 mm overall length (approximately 4.29 inches), this bit delivers repeatable performance in general-purpose applications across ferrous and non-ferrous materials. It is used by machinists, tool-and-die technicians, and CNC operators working in precision fabrication and production shops.

This drill bit is rated for aluminum and other non-ferrous workpiece materials under primary workpiece material code N. The right-hand spiral flute configuration with regular spiral type promotes efficient chip evacuation during through-hole and blind-hole drilling operations. With a 5xD flute-to-diameter ratio and a maximum drilling depth of 58.05 mm (approximately 2.29 inches), it suits standard jobber-length drilling cycles on manual mills, drill presses, and CNC machining centers. The straight-cylindrical shank with a 7.30 mm shank diameter and 40 mm shank length seats securely in standard collets and drill chucks without adapters.

Key Features

• Solid carbide K40 grade construction for rigidity and wear resistance in high-speed drilling
• FIREX coating reduces heat buildup and extends tool life in non-ferrous and aluminum applications
• 118-degree faceted drill point with web thinning for accurate self-centering and reduced thrust force
• Right-hand, regular spiral flute geometry with 5xD ratio promotes clean chip evacuation
• Straight-cylindrical shank (7.30 mm diameter, 40 mm length) fits standard collets and drill chucks
• Built to DIN specification designation for dimensional consistency across the Series 2464 product line

Compatibility

Designed as a general-purpose jobber-length drill bit for use with standard drill chucks and collet systems accepting a 7.30 mm straight-cylindrical shank. Suited for aluminum and non-ferrous workpiece materials as identified by primary workpiece material code N.

Installation Notes

Installation and use should be performed by qualified machinists or CNC operators familiar with cutting tool setup and machine operation. Ensure the spindle is fully stopped and the machine is powered down before loading or changing the bit in the chuck or collet. Verify shank seating depth and runout before beginning any drilling cycle. Coolant-through is not supported on this tool; use external flood or mist coolant as appropriate for the workpiece material and cutting speed.
