Guhring 9024640037000 Carbide Jobber Drill Bit 3.7mm

Product Description

The GUHRING 9024640037000 is a solid carbide jobber-length drill bit designed for precision drilling in aluminum and other non-ferrous materials. Built to DIN standards under Guhring Series 2464, it features a FIREX coating for improved wear resistance and heat management during high-speed cutting operations. The bit runs a 118-degree faceted point angle with web thinning for reduced thrust and cleaner entry. At 3.7 mm in diameter with a 2.76-inch overall length, it is sized for tight-tolerance work where carbide rigidity and coating durability are required. Licensed machinists, tool-and-die technicians, and CNC operators are the primary users.

This drill bit is rated for general-purpose use with a primary workpiece material designation of aluminum (Material Code N), making it well-suited for aerospace component work, fixture fabrication, and production machining where consistent hole geometry and surface finish matter. The 5xD flute-to-diameter ratio and 1.54-inch flute length provide adequate chip evacuation in typical jobber-length applications. It is sold individually and is appropriate for use in CNC machining centers, drill presses, and hand-held pneumatic or electric drilling equipment when a collet or drill chuck matched to the 3.7 mm straight-cylindrical shank is available.

Key Features

• FIREX coating for extended tool life and reduced built-up edge in non-ferrous materials
• 118-degree faceted point angle with web thinning for reduced entry force and improved centering
• Solid carbide construction (Material Grade K40) for rigidity in precision hole-making
• Right-hand cut, regular spiral flute for standard chip evacuation
• Straight-cylindrical shank compatible with standard collets and drill chucks
• DIN specification designation ensures dimensional consistency across production runs

Compatibility

Designed for use with collets or drill chucks accepting a 3.7 mm straight-cylindrical shank. Primary workpiece material designation is aluminum (Code N); suited for general-purpose drilling in non-ferrous materials as classified under Guhring Series 2464.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tooling technicians familiar with carbide tooling handling procedures. Ensure the spindle is fully stopped and the machine is locked out before inserting or removing the bit from the chuck or collet. Carbide is brittle compared to high-speed steel — avoid side-loading, interrupted cuts without proper feed control, or dropping the bit on hard surfaces. Verify runout at the shank before beginning a production run to protect both the tool and the workpiece.
