Guhring 9024640040000 Jobber Drill Bit 4mm Carbide

Product Description

The GUHRING 9024640040000 is a jobber-length drill bit designed for precision drilling in non-ferrous and light alloy materials, particularly aluminum. Built from solid carbide grade K40 and finished with a FIREX coating, this bit delivers consistent cutting performance in production and maintenance environments. It features a 118-degree faceted point angle and a web-thinned tip geometry that reduces entry force and improves chip evacuation. The 4 mm diameter and straight-cylindrical shank suit standard drill chucks and collet holders. Machinists, toolroom technicians, and maintenance mechanics are the typical end users for this style of bit.

This drill bit is configured for right-hand cut with a regular spiral flute pattern rated at a 5xD flute-to-diameter ratio. It is suited for general-purpose drilling operations in aluminum and other non-ferrous materials classified under material code N. Typical applications include production machining, fixture fabrication, and precision maintenance drilling where a solid carbide bit is required for tool life and dimensional accuracy. The straight-cylindrical shank allows direct mounting in standard chucks without adapters.

Key Features

• Solid carbide K40 grade substrate for hardness and wear resistance in non-ferrous materials
• FIREX coating reduces friction and extends tool life compared to uncoated carbide
• Web-thinned 118-degree faceted point reduces thrust force and improves hole entry accuracy
• Two-flute regular spiral design promotes efficient chip evacuation at typical feed rates
• Straight-cylindrical shank compatible with standard collets and drill chucks
• Conforms to DIN specification for consistent dimensional standards

Compatibility

Designed as a general-purpose jobber-length carbide drill bit for use in CNC machining centers, drill presses, and hand-held drilling equipment accepting a 4 mm straight-cylindrical shank. Primary workpiece material is aluminum and other non-ferrous materials per material code N.

Installation Notes

Installation and tool changes should be performed with the machine fully powered down and spindle locked. Secure the shank fully within the collet or chuck to the manufacturer-recommended insertion depth before tightening. Verify runout with an indicator before production use, as carbide bits are sensitive to lateral load from misalignment. Follow applicable shop safety procedures and machine manufacturer guidelines when setting feed rates and spindle speeds for carbide tooling.
