Guhring 9024640039900 Jobber Drill Bit No.22 Carbide

Product Description

The GUHRING 9024640039900 is a solid carbide jobber length drill bit sized to wire gauge No. 22 (0.1570 inches decimal), engineered for general-purpose drilling in aluminum and non-ferrous materials. It carries a FIREX coating to improve surface hardness and extend tool life in production environments. The drill features a 118-degree faceted point angle with web thinning for easier penetration and reduced thrust at entry. With an overall length of 2.95 inches and a flute length of 1.69 inches, this bit fits standard toolholding with a straight-cylindrical shank. It is used by machinists, maintenance technicians, and fabricators working on precision hole applications.

This drill bit is suited for drilling aluminum and similar non-ferrous workpiece materials (Primary Workpiece Material Code: N) in both job-shop and production settings. The two-flute spiral design with a regular spiral type promotes efficient chip evacuation in softer materials. The Series 2464 designation follows DIN specification standards. The maximum drilling depth is 1.457 inches (37.02 mm), making it appropriate for through-hole and moderate-depth blind-hole work in light-metal components and assemblies.

Key Features

• Solid carbide construction in material grade K40 for rigidity and wear resistance
• FIREX coating for extended tool life and improved surface performance
• 118-degree faceted point angle with web thinning to reduce entry thrust
• Two-flute regular spiral design optimized for chip evacuation in aluminum
• Straight-cylindrical shank (3.99 mm diameter) compatible with standard drill chucks and collets
• DIN-specification Series 2464 for consistent dimensional standards

Compatibility

Designed as a general-purpose jobber length drill bit per DIN specification, Series 2464, suitable for use in standard drill chucks and collets accepting a 3.99 mm straight-cylindrical shank. No coolant-through capability; intended for conventional drilling setups.

Installation Notes

Installation and operation should be performed by qualified machinists or tooling technicians familiar with rotating cutting tools. Secure the shank fully in the chuck or collet before use, and verify runout is within acceptable limits to protect the carbide from breakage. Solid carbide tooling is brittle compared to high-speed steel; avoid side loading or interrupted cuts that were not accounted for in the application setup. Follow applicable shop safety protocols and machine guarding requirements during operation.
