Guhring 9024630150000 Carbide Stub Drill Bit 15mm

Product Description

The GUHRING 9024630150000 is a solid carbide stub-length (screw machine length) drill bit designed for precision drilling in production and machining environments. Built to DIN 6539 standards, this right-hand cut bit features a 118-degree faceted point with web thinning for reduced thrust and cleaner entry. The spiral flute geometry and straight-cylindrical shank make it compatible with standard drill chucks and collet holders. At 15mm (0.5906 inches) in diameter with an overall length of 4.37 inches and a flute length of 2.205 inches, it is sized for rigid, close-tolerance work. Licensed machinists and CNC operators are the primary installers of this tool.

This drill bit is rated for general-purpose performance with a primary workpiece material designation of aluminum, making it well suited for high-speed drilling in aluminum stock, plate, and castings. The stub-length body reduces deflection compared to jobber-length bits, which is advantageous in short-travel drilling setups or on CNC machining centers with limited Z-axis travel. The 3xD flute-to-diameter ratio supports chip evacuation in moderate-depth holes up to a maximum drilling depth of 1.319 inches (33mm).

Key Features

• Solid carbide construction rated to material grade K40 for hardness and wear resistance
• 118-degree faceted drill point with web thinning for reduced entry thrust
• Stub-length (screw machine length) body minimizes deflection in tight-clearance setups
• Right-hand cut spiral flute with 3xD ratio for effective chip evacuation
• Straight-cylindrical shank fits standard drill chucks and collet systems
• Manufactured to DIN 6539 specification with a diameter tolerance of +0.000 to -0.010mm

Compatibility

Designed as a general-purpose stub-length drill bit for use in standard drill chucks and collet-style toolholders accepting a 15mm straight-cylindrical shank. Primary workpiece material is aluminum per manufacturer designation.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Confirm the shank is fully seated and the chuck or collet is torqued to the machine manufacturer's specification before operation. Do not exceed the recommended maximum drilling depth of 1.319 inches per pass without retracting to clear chips.
