Guhring 9024640019900 Jobber Drill Bit No. 47 Carbide

Product Description

The GUHRING 9024640019900 is a solid carbide jobber length drill bit in wire gauge size No. 47 (0.0785 inches decimal equivalent) with a 118-degree faceted point angle. Built to DIN specification from K40 carbide grade, it features a FIREX coating that improves wear resistance and heat dissipation during cutting. The 2-flute spiral design with a regular spiral type provides efficient chip evacuation, and the web-thinned point reduces thrust and improves centering. Overall length is 1.93 inches (49 mm), with a flute length of 0.94 inches (24 mm) and a straight-cylindrical shank diameter of 1.99 mm. This is a general-purpose, right-hand-cut drill bit suited for precision small-hole work.

This drill bit is designed primarily for machining aluminum and other non-ferrous materials (primary workpiece material code N), making it well suited for HVAC sheet metal fabrication, electrical panel work, plumbing fixture drilling, and general light-metal applications in trade shop or field environments. The 5xD flute-to-diameter ratio and maximum drilling depth of 0.828 inches (21.02 mm) position it for through-hole and blind-hole work in thin to medium stock. It is sold individually and suited for use in standard drill presses, CNC machining centers, and handheld power drills with compatible collets or chucks.

Key Features

• Solid carbide K40 grade construction for hardness and wear resistance in non-ferrous materials
• FIREX coating reduces friction and extends tool life at elevated cutting temperatures
• 118-degree faceted point with web thinning for reduced entry thrust and accurate centering
• Right-hand cut, regular spiral flute for consistent chip removal
• Straight-cylindrical shank (1.99 mm diameter) fits standard collets and drill chucks
• DIN specification compliance, Series 2464, for dimensional consistency

Compatibility

Designed as a general-purpose replacement or stock drill bit for applications requiring wire gauge No. 47 (0.0785 inch) hole size. No specific machine or system compatibility was stated in the product data.

Installation Notes

Install and operate this drill bit according to the tool manufacturer's recommended speeds and feeds for solid carbide tooling in the target workpiece material. Power down and de-energize all equipment before changing tooling. Secure the shank fully in the collet or chuck to the correct engagement depth before operation. Solid carbide tooling is brittle compared to high-speed steel — avoid side-loading or using in applications with significant vibration without proper workholding.
