Guhring 9007300013000 Stub Drill Bit 0.0512 in Solid Carbide

Product Description

The GUHRING 9007300013000 is a stub-length (screw machine length) solid carbide drill bit designed for precise, high-accuracy drilling in tight-clearance setups. Built to DIN 6539 standards, it measures 1.30 mm (0.0512 inches) in diameter with an overall length of 28.00 mm. The 118-degree faceted point geometry and web-thinned tip reduce thrust force and improve entry accuracy on non-ferrous and soft materials. With a straight-cylindrical shank and right-hand spiral flute, this bit is intended for use in CNC machining centers, drill presses, and screw machine setups where rigidity and runout control are critical. Installation and use are typically handled by machinists and tooling technicians.

This drill bit is suited for general-purpose drilling applications, with a primary designation for aluminum and similar non-ferrous workpiece materials. The stub-length design limits overhang, increasing stiffness and reducing deflection in applications where hole location tolerance is tight. The 3xD flute-to-diameter ratio provides adequate chip evacuation for depths up to 6.05 mm (0.2380 inches). It is appropriate for use in production machining environments, job shops, and maintenance repair operations requiring small-diameter precision holes.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance in small-diameter drilling
• 118-degree faceted drill point with web-thinned tip for reduced entry thrust
• Stub-length (DIN 6539) design minimizes deflection and improves hole location accuracy
• Right-hand, regular spiral flute for consistent chip evacuation
• Straight-cylindrical shank (h8 diameter tolerance) for standard collet and chuck compatibility
• Bright/uncoated finish suitable for aluminum and general-purpose non-ferrous applications

Compatibility

Designed as a general-purpose stub-length drill bit per DIN 6539 specifications, compatible with standard straight-shank collets and drill chucks accepting 1.30 mm shank diameters. Primary workpiece material designation is aluminum.

Installation Notes

This drill bit should be installed and operated by qualified machinists or tooling technicians familiar with small-diameter carbide tooling. Always confirm spindle runout is within acceptable limits before use, as carbide is brittle and sensitive to lateral loading. Secure the shank fully in a precision collet or drill chuck rated for the spindle speed being used. Avoid hand-feeding with excessive pressure on small-diameter carbide drills, as side load or deflection can cause bit fracture.
