Guhring 9024640019000 Carbide Jobber Drill Bit 1.9mm

Product Description

The GUHRING 9024640019000 is a solid carbide jobber-length drill bit designed for precise, small-diameter drilling in production and maintenance environments. Built to DIN specification in Series 2464, it features a 118-degree faceted point and a FIREX coating that improves heat and wear resistance over uncoated carbide. The 1.9 mm diameter and straight-cylindrical shank pair with standard drill chucks and collet holders. With a regular spiral flute and web-thinned point geometry, it starts cleanly and evacuates chips efficiently. This bit is intended for use by machinists, toolmakers, and CNC operators working in job shop and production settings.

This drill bit is rated for general-purpose drilling with a primary workpiece material designation of aluminum and non-ferrous materials (Material Code N). The 5xD flute-to-diameter ratio and 19.15 mm maximum drilling depth make it well suited for through-holes and blind holes in thin-to-medium stock. Its compact overall length of 46 mm suits close-tolerance setups in CNC machining centers, manual drill presses, and benchtop drilling fixtures where rigidity and runout control are critical.

Key Features

• Solid carbide construction in material grade K40 for rigidity and edge retention in non-ferrous applications
• FIREX coating provides enhanced thermal and abrasion resistance compared to uncoated carbide
• 118-degree faceted point with web thinning reduces entry force and improves centering accuracy
• Right-hand cut with regular spiral flute for reliable chip evacuation in aluminum and similar materials
• Straight-cylindrical shank compatible with standard drill chucks and ER collet systems
• Built to DIN specification under Series 2464 for consistent dimensional tolerances across production runs

Compatibility

Designed as a general-purpose jobber-length drill bit for use in CNC machining centers, manual drill presses, and hand drilling equipment fitted with standard chucks or collet holders accepting a 1.9 mm straight-cylindrical shank. Rated for aluminum and non-ferrous workpiece materials per Material Code N classification.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom personnel familiar with carbide tooling practices. Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable limits, as carbide is brittle and sensitive to lateral loading. Always match spindle speed and feed rate to the workpiece material and consult the manufacturer feed-speed tables for small-diameter carbide drills. Inspect the cutting edges before each use and replace at first sign of chipping or wear to avoid workpiece damage or bit breakage.
