Guhring 9024630029000 Stub Drill Bit 0.1142 in Carbide

Product Description

The GUHRING 9024630029000 is a stub-length (screw machine length) solid carbide twist drill bit designed for precision hole-making in high-production and CNC machining environments. Built to DIN 6539 standards from K40 grade carbide, it features a 118-degree faceted point angle with web thinning for reduced thrust and cleaner entry. The 2-flute spiral design with a straight-cylindrical shank promotes chip evacuation and consistent hole geometry. At 0.1142 inches (2.90 mm) in diameter, this bit is sized for fine-tolerance work and is intended for use by machinists, tool and die technicians, and CNC operators.

This drill bit is optimized for aluminum as its primary workpiece material and suits general-purpose drilling in stub-length applications where rigidity and minimized runout are critical. The shorter flute length relative to overall length improves stiffness, making it well suited for high-speed drilling cycles on lathes, drill presses, and machining centers. A coated finish extends tool life across repeated production runs. The Series 2463 designation identifies it within the GUHRING stub-drill product family.

Key Features

• Solid carbide construction, K40 grade — maintains hardness and edge integrity at elevated cutting speeds
• 118-degree faceted drill point with web thinning reduces entry thrust and improves point accuracy
• 2-flute regular spiral geometry promotes chip clearance in aluminum and similar non-ferrous materials
• Stub (screw machine) length provides increased rigidity versus jobber-length drills in the same diameter
• Straight-cylindrical shank compatible with standard drill chucks and collet systems
• Meets DIN 6539 dimensional and tolerance standards

Compatibility

Designed as a general-purpose stub-length drill bit for use in CNC machining centers, manual drill presses, and lathes accepting straight-cylindrical shanks at 2.90 mm shank diameter. Primary workpiece material rating is aluminum; consult cutting data charts for use on other non-ferrous or composite materials.

Installation Notes

Installation and tool changes should be performed with the machine at a full stop and spindle power locked out per shop safety procedures. Ensure the collet or chuck is clean and free of debris before seating the shank to maintain runout tolerances. Cutting speed and feed rate selection should follow the manufacturer cutting data for the workpiece material. Inspect the cutting edges under magnification before each use — solid carbide edges are brittle and can micro-chip if dropped or improperly stored.
