Guhring 9024640025300 Jobber Drill Bit No 39 Solid Carbide

Product Description

The GUHRING 9024640025300 is a solid carbide jobber length drill bit in wire gauge size No. 39, with a decimal diameter of 0.0995 inches. It features a FIREX coating for improved wear resistance and heat management during cutting operations. The drill has a 118-degree faceted point angle, a right-hand spiral flute, and a straight-cylindrical shank with a 2.53 mm shank diameter. With an overall length of 57 mm (2.24 inches) and a flute length of 30 mm (1.18 inches), this bit is designed for general-purpose drilling. It is installed by machinists and metalworking tradespeople working with precision drill presses, CNC machines, or hand-held drilling equipment.

This drill bit is engineered for use in aluminum and non-ferrous materials, as indicated by the N primary workpiece material code. The Series 2464 design follows DIN specification standards and carries a 5xD flute-by-diameter ratio suitable for moderate-depth holes in production and maintenance machining environments. The web-thinned point reduces thrust requirements at entry, making it well suited for close-tolerance work on thin or soft stock. Maximum drilling depth is 26.21 mm (1.032 inches).

Key Features

• Solid carbide construction in material grade K40 for rigidity and edge retention
• FIREX coating provides thermal and wear resistance for extended tool life
• 118-degree faceted point with web thinning reduces entry thrust and improves centering
• Right-hand cut, regular spiral flute promotes efficient chip evacuation
• Straight-cylindrical shank compatible with standard drill chucks and collets
• DIN-specification Series 2464 design ensures consistent dimensional accuracy

Compatibility

Designed as an OEM-specification replacement or direct-use solid carbide drill bit for standard drill chucks and collet systems accepting a 2.53 mm straight-cylindrical shank, per DIN Series 2464 standards.

Installation Notes

Installation and use should be performed by qualified machinists or metalworking technicians familiar with cutting tool safety practices. Ensure the drill press, CNC spindle, or hand tool is powered down and locked out before changing or securing tooling. Confirm chuck or collet runout is within acceptable tolerance before drilling, as carbide is brittle and susceptible to breakage under lateral load or vibration. Do not use this bit on hardened steel or materials outside its rated application range.
