Guhring 9024630035000 Carbide Drill Bit 3.50mm 0.1378in 118deg

Product Description

The GUHRING 9024630035000 is a solid carbide screw machine length (stub) drill bit designed for precision drilling in production and machining environments. Built to DIN 6539 standards and belonging to Series 2463, this bit features a 118-degree faceted drill point, a web-thinned tip for reduced thrust and cleaner entry, and a regular spiral flute with a right-hand cutting direction. The 3.50 mm (0.1378 inches) diameter is held to a tight tolerance of +0.000 to -0.010 mm, making it well-suited for applications where hole accuracy matters. At 0.05 pounds, the bit is lightweight and fits a straight-cylindrical shank for standard chuck mounting.

This drill bit is rated for general-purpose use with a primary workpiece material of aluminum, though its solid carbide construction and coated finish support drilling in a range of non-ferrous and softer ferrous materials. The stub-length body — 2.047 inches overall with a 0.787-inch flute length — provides added rigidity compared to jobber-length bits, reducing deflection in short-hole and spot-drilling operations. A maximum drilling depth of 0.581 inches makes it appropriate for shallow through-holes and blind holes in production machining, CNC drilling, and screw machine applications. Machinists and CNC operators working in job shops, manufacturing facilities, and production lines are the primary users.

Key Features

• Solid carbide construction with a coated finish for extended tool life and wear resistance
• 118-degree faceted drill point for reliable self-centering and clean hole entry
• Web-thinned tip reduces axial thrust and improves chip evacuation
• Stub (screw machine) length body increases rigidity and minimizes deflection
• Right-hand spiral flute optimized for aluminum and general-purpose materials
• Tight diameter tolerance of +0.000 to -0.010 mm for consistent hole sizing

Compatibility

Designed as a general-purpose stub-length drill bit for use in CNC machining centers, drill presses, and screw machines equipped with standard straight-cylindrical chuck or collet systems accepting a 3.50 mm shank diameter. Primary workpiece material is aluminum per manufacturer specification.

Installation Notes

This bit is installed by a machinist or CNC operator into a standard straight-cylindrical chuck or collet rated for the 3.50 mm shank diameter. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Verify chuck runout before use, as excessive runout will degrade hole tolerance and reduce tool life. Follow applicable shop safety protocols and machine manufacturer guidelines when setting speeds and feeds for carbide tooling in the target workpiece material.
