Guhring 9024640120000 Jobber Drill Bit 12mm Carbide

Product Description

The GUHRING 9024640120000 is a jobber length drill bit engineered for precision drilling in aluminum and other non-ferrous materials. Built from solid carbide grade K40, it features a FIREX coating that extends tool life by reducing heat buildup and surface friction at the cutting zone. The 118-degree faceted point with web thinning promotes accurate entry and reduces thrust force on the workpiece. At 5.94 inches overall length with a 3.98-inch spiral flute, this bit delivers consistent chip evacuation in a standard jobber profile. Machinists and toolroom technicians working on CNC machining centers and drill presses will find this bit sized for direct collet or chuck mounting.

The 9024640120000 is designed for general-purpose drilling in aluminum and similar non-ferrous workpiece materials, identified under primary workpiece material code N. The 12 mm diameter with a straight-cylindrical shank seats into standard 12 mm collets or three-jaw chucks without adapters. A flute-to-diameter ratio of 5xD and a maximum drilling depth of 3.27 inches (83 mm) make it appropriate for through-hole and moderate-depth blind-hole applications in production and job-shop environments.

Key Features

• Solid carbide K40 grade construction for rigidity and wear resistance in non-ferrous cutting
• FIREX coating reduces friction and extends tool life compared to uncoated carbide
• 118-degree faceted drill point with web thinning for clean entry and reduced thrust
• Right-hand, regular spiral flute promotes efficient chip evacuation
• Straight-cylindrical shank fits standard collets and chucks directly
• DIN specification designation ensures dimensional conformance to recognized standards

Compatibility

Designed as an OEM-standard replacement or direct-use jobber drill bit for 12 mm straight-cylindrical collet chucks and drill press chucks on CNC machining centers, knee mills, and drill presses. Sized within the 10.00 to 12.50 mm drill bit size range per the Series 2464 product family.

Installation Notes

Installation and tool changes should be performed by qualified machinists or toolroom technicians with the machine powered down and the spindle fully stopped before seating or removing the bit. Ensure the collet or chuck bore is clean and free of chips before inserting the shank to maintain runout tolerances. Refer to the machine manufacturer guidelines and applicable shop safety procedures when setting feed rates and spindle speeds for carbide tooling in aluminum applications.
