Guhring 9024640011900 Jobber Drill Bit 3/64 in Carbide

Product Description

The GUHRING 9024640011900 is a solid carbide jobber length drill bit designed for precision small-diameter drilling in trade and industrial applications. Built to DIN specification in the Series 2464, it features a 118-degree faceted point angle with web thinning for improved centering and reduced thrust. The FIREX coating extends tool life in demanding cuts. At 3/64 inch (0.0469 inch decimal) diameter with an overall length of 1.42 inches, this bit handles tight-tolerance work where carbide rigidity and coating performance are required. Right-hand cut with a regular spiral flute geometry and a straight-cylindrical shank ensure compatibility with standard drill chucks and collet systems.

This drill bit is suited for general-purpose drilling in non-ferrous metals, with aluminum listed as the primary workpiece material (material code N). The 5xD flute-to-diameter ratio and a maximum drilling depth of 0.56 inches make it appropriate for through-hole and shallow blind-hole applications in production and repair environments. Machinists, toolroom technicians, and precision sheet-metal workers will find it useful for small-diameter work requiring consistent diameter tolerance of -0.012 to 0.000 mm.

Key Features

• Solid carbide construction in material grade K40 for rigidity and wear resistance at small diameters
• FIREX coating for extended tool life in non-ferrous and abrasive material drilling
• 118-degree faceted point with web thinning reduces walk and entry thrust
• Right-hand cut, regular spiral flute with 2 flutes for efficient chip evacuation
• Straight-cylindrical shank fits standard drill chucks and collet holders
• Built to DIN specification, Series 2464, for consistent dimensional standards

Compatibility

Designed as a general-purpose jobber length drill bit compatible with standard drill chucks and collet systems accepting a 1.19 mm straight-cylindrical shank; primary workpiece material is aluminum and other non-ferrous metals per material code N.

Installation Notes

Installation and use should be performed by machinists or qualified technicians familiar with small-diameter carbide tooling. Secure the shank fully in the chuck or collet before operation and verify runout is within tolerance, as carbide bits at this diameter are brittle and susceptible to breakage from lateral loading. Power down the machine and confirm it is fully stopped before changing tooling. Follow applicable shop safety standards for rotating equipment when operating at recommended speeds for carbide in non-ferrous materials.
