Guhring 9006520018000 Jobber Drill Bit 1.8mm Hss Tin

Product Description

The GUHRING 9006520018000 is a jobber length twist drill bit designed for precision drilling in aluminum and other non-ferrous and ferrous materials. Built from high-speed steel (HSS) with a titanium nitride (TiN) coating, it delivers extended tool life and reduced friction during cutting. The bit measures 1.8 mm in diameter (0.0709 inches) with an overall length of 46 mm and features a parabolic flute design for efficient chip evacuation. The 130-degree split point geometry provides accurate centering and reduces the tendency to walk on entry. This bit is suited for production shop environments and is installed by machinists and tool and die professionals.

This drill bit is intended for use in light-duty to medium-duty drilling applications in aluminum, plastics, and low-alloy steels. Its parabolic flute profile and web-thinned point make it a practical choice for through-hole work in CNC machining centers, drill presses, and hand-held power tools where small-diameter precision is required. The straight-cylindrical shank seats directly into standard drill chucks and collet holders without modification. Conforming to DIN 338 standards, it fits into workflows where metric tooling is specified.

Key Features

• TiN coating reduces surface friction and extends cutting life compared to uncoated HSS
• Parabolic flute geometry promotes fast, clean chip removal in deep holes
• 130-degree point angle with web thinning improves self-centering and reduces thrust force
• Straight-cylindrical shank at 0.0709 inches diameter fits standard collets and drill chucks
• DIN 338 compliant construction supports metric tooling specifications
• Right-hand cut, two-flute design for conventional clockwise drilling operations

Compatibility

Designed as a DIN 338 jobber length drill bit in the GUHRING Series 652, suitable for use in standard drill chucks and collet systems accepting a 0.0709-inch straight-cylindrical shank. Primary workpiece material compatibility includes aluminum, non-ferrous metals, and low-alloy steels per material codes K, N, and P.

Installation Notes

Install this bit into a clean, properly sized collet or drill chuck and verify runout before beginning a cut. Secure the workpiece firmly to prevent movement during drilling. Small-diameter bits are susceptible to breakage from side loading — maintain consistent feed pressure and avoid lateral deflection. Follow applicable shop safety procedures and machine manufacturer guidelines when setting spindle speed and feed rate for the material being drilled.
