Guhring 9024640053100 Jobber Drill Bit Size 4 Carbide

Product Description

The GUHRING 9024640053100 is a solid carbide jobber length drill bit designed for precision drilling in aluminum and other non-ferrous materials. Sized to wire gauge number 4 (0.2090 inches decimal equivalent), this bit features a 118-degree faceted point, a FIREX coating for improved wear resistance, and a right-hand spiral flute for efficient chip evacuation. The straight-cylindrical shank measures 5.31 mm in diameter, and the overall length is 93 mm (3.66 inches). Web thinning reduces thrust requirements at the cutting tip. Licensed HVAC, machining, and maintenance professionals working with aluminum components will find this bit well matched to general-purpose production and repair drilling tasks.

This drill bit is intended for use in CNC machining centers, drill presses, and hand-held power drills where a straight-cylindrical shank is compatible. It targets aluminum as its primary workpiece material (material code N) but is built for general-purpose use within the 0.2000 to 0.2500 inch drill diameter range. The 2-flute regular spiral geometry and 5xD flute-to-diameter ratio make it suitable for moderate-depth holes. Maximum drilling depth is 49.04 mm (1.93 inches). Series 2464 follows DIN specification standards, and the tool is manufactured from K40 grade solid carbide for consistent edge retention in production environments.

Key Features

• Wire size number 4, 0.2090 inch decimal equivalent for precise hole sizing
• FIREX coating improves surface hardness and extends tool life in non-ferrous applications
• 118-degree faceted point with web thinning reduces entry thrust and improves centering
• K40 grade solid carbide construction maintains edge integrity under repeated use
• Right-hand, 2-flute regular spiral geometry promotes clean chip evacuation
• Straight-cylindrical shank compatible with standard drill chucks and collet holders

Compatibility

Designed as a general-purpose replacement or production drill bit for applications requiring a wire gauge number 4 (0.2090 inch) hole diameter with a straight-cylindrical shank, conforming to DIN specification standards under Series 2464.

Installation Notes

Installation and use of this bit should be performed by qualified machinists or maintenance technicians familiar with carbide tooling. Secure the straight-cylindrical shank firmly in a properly sized collet or drill chuck before operation to prevent runout. Carbide tooling is brittle and should not be subjected to side loads or impact; use appropriate feeds and speeds for the workpiece material to avoid tip fracture. Inspect the cutting edge and FIREX coating before each use and replace the bit if chipping or coating loss is observed.
