Guhring 9024640063500 Jobber Drill Bit Letter E Carbide

Product Description

The GUHRING 9024640063500 is a solid carbide jobber length drill bit sized at Letter E (0.25 inches / 0.2500 decimal inch) with a 118-degree faceted point angle. It is finished with FIREX coating for improved wear resistance and heat tolerance during drilling operations. The bit features a 2-flute spiral flute design with web thinning for easier penetration and reduced thrust force. With an overall length of 3.98 inches (101 mm) and a flute length of 2.48 inches (63 mm), it is designed for general-purpose drilling applications. It is installed by machinists and tooling technicians in metalworking and fabrication environments.

This drill bit is built for drilling aluminum and other non-ferrous materials, corresponding to workpiece material code N. The straight-cylindrical shank with a diameter of 6.35 mm fits standard drill chucks and collets. It is suited for general-purpose production drilling in machine shop environments, CNC drilling centers, and manual drill press setups. The 5xD flute-to-diameter ratio supports chip evacuation in moderate-depth holes. Maximum drilling depth is 2.106 inches (53.48 mm). The Series 2464 designation follows DIN specification standards, making it compatible with metric and inch tooling setups common in North American and European shop environments.

Key Features

• Solid carbide construction in material grade K40 for rigidity and wear resistance
• FIREX coating reduces friction and extends tool life in aluminum and non-ferrous drilling
• 118-degree faceted point with web thinning for reduced entry thrust and accurate starts
• 2-flute spiral (regular) design promotes efficient chip evacuation
• Straight-cylindrical shank (6.35 mm diameter) for compatibility with standard chucks and collets
• Right-hand cut, general-purpose tool performance rated for production and maintenance drilling

Compatibility

Designed as a general-purpose OEM-style jobber length drill bit suitable for use in standard drill chucks, collet systems, and CNC tool holders that accept a 6.35 mm straight-cylindrical shank. Primary workpiece material is aluminum (material code N). Series 2464, DIN specification.

Installation Notes

This tool is installed and replaced by machinists, toolroom technicians, or CNC setup operators. Before changing tooling, de-energize and lock out the machine per standard OSHA lockout/tagout procedures. Ensure the shank seating surface and chuck or collet bore are clean and free of chips before securing the bit. Do not exceed the maximum drilling depth of 2.106 inches in a single pass without retracting to clear chips.
