Guhring 9024630140000 Solid Carbide Stub Drill Bit 14mm

Product Description

The GUHRING 9024630140000 is a stub-length (screw machine length) solid carbide drill bit designed for precision hole-making in production and maintenance environments. Built to DIN 6539 standards with a K40 carbide grade, it cuts a 14.00 mm (0.5512 inches) diameter hole with a 118-degree faceted point that promotes accurate entry and self-centering. The web-thinned tip reduces thrust force at cut entry. With a coated finish and right-hand spiral flute geometry, this bit is suited for machinists, tool-and-die trades, and production drilling operations where tight tolerances and tool life matter.

This drill bit is optimized for use on aluminum as its primary workpiece material, making it a solid fit for aerospace, automotive, and general fabrication shops running aluminum stock. The stub-length body keeps the tool stiff in short-reach setups, minimizing deflection in drill press, CNC machining center, and manual lathe tailstock applications. The 3xD flute-to-diameter ratio and regular spiral flute design support chip evacuation in through-hole and shallow blind-hole drilling. No coolant-through feature is present, so flood or mist coolant applied externally is the standard approach for this bit configuration.

Key Features

• Solid carbide K40 grade construction for hardness and wear resistance
• 118-degree faceted drill point with web thinning for reduced entry thrust
• Coated finish extends tool life in high-cycle production runs
• Right-hand cut with regular spiral flutes for consistent chip evacuation
• Stub (screw machine) length body minimizes deflection in short-reach setups
• Meets DIN 6539 specification for dimensional consistency

Compatibility

Designed as an OEM-style stub-length carbide drill bit for use in standard straight-cylindrical shank toolholders, drill chucks, and collet systems accepting a 14.00 mm shank diameter. Primary workpiece material designation is aluminum per manufacturer specification.

Installation Notes

Installation and use should be performed by a qualified machinist or tooling technician familiar with carbide tooling requirements. Ensure the machine spindle and toolholder are fully powered down and locked out before loading or changing the bit. Carbide is brittle — avoid side loads, interrupted cuts without proper setup, or dropping the tool on hard surfaces. Consult the machine manufacturer guidelines and applicable shop safety codes when setting feeds, speeds, and coolant delivery for carbide tooling.
