Guhring 9024640035000 Jobber Drill Bit 3.5mm Carbide

Product Description

The GUHRING 9024640035000 is a jobber-length drill bit designed for precision drilling in aluminum and other non-ferrous materials. Built from solid carbide grade K40, it carries a FIREX coating that reduces friction and extends tool life in demanding cutting cycles. The bit measures 3.5 mm in diameter with an overall length of 70 mm (approximately 2.76 inches) and a flute length of 39 mm (approximately 1.54 inches). The 118-degree faceted point geometry and web-thinned tip reduce entry force and improve centering accuracy. This is a general-purpose tool suited for CNC machining centers and precision drill presses operated by machinists and tool-and-die professionals.

This drill bit fits applications requiring consistent, repeatable hole quality in aluminum and similar non-ferrous workpieces, corresponding to primary workpiece material code N. The straight-cylindrical shank seats directly into standard collet chucks and drill chucks without adaptation. With a 5xD flute-to-diameter ratio and a maximum drilling depth of 33.75 mm (approximately 1.33 inches), it is well suited to through-hole and shallow blind-hole work in production and job-shop environments. The regular spiral flute promotes efficient chip evacuation, reducing heat buildup at the cutting edge.

Key Features

• Solid carbide K40 grade construction for rigidity and wear resistance
• FIREX coating reduces tool wear and surface friction during cutting
• 118-degree faceted point with web thinning for accurate self-starting entry
• Right-hand cut with regular spiral flute for efficient chip removal
• Straight-cylindrical shank fits standard collet and drill chuck systems
• General-purpose Series 2464 design built to DIN specification standards

Compatibility

Designed as a general-purpose jobber-length drill bit for use in CNC machining centers, knee mills, and drill presses accepting a 3.5 mm straight-cylindrical shank. Primary workpiece material is aluminum and non-ferrous metals (material code N).

Installation Notes

Installation and use should be performed by a qualified machinist familiar with carbide tooling. Secure the shank fully in the collet or drill chuck and verify runout before operation, as carbide is brittle and sensitive to lateral loading. Do not use in hand-held drills; carbide tooling requires a rigid, vibration-controlled spindle. Coolant-through is not supported on this bit, so apply cutting fluid externally when drilling at higher feed rates.
