Guhring 9024630020800 Screw Machine Drill Bit 0.082in

Product Description

The GUHRING 9024630020800 is a stub-length (screw machine length) solid carbide drill bit designed for precision drilling in production and machining environments. Built to DIN 6539 standards with a K40 carbide grade, it cuts a 0.082-inch (wire size #45) hole with a 118-degree faceted point and a web-thinned tip for improved centering and reduced thrust. The straight-cylindrical shank seats directly in standard drill chucks or collets. With two spiral flutes and a 3xD flute-to-diameter ratio, this bit is suited for machinists, tool-and-die technicians, and CNC setup personnel running short-reach drilling operations.

This bit is configured for right-hand cut in general-purpose applications, with aluminum listed as the primary workpiece material. The stub-length body keeps the tool rigid and minimizes deflection in close-tolerance work. A coated finish extends tool life in repetitive cycling. The overall length of 1.496 inches and flute length of 0.472 inches make it appropriate for shallow-hole work on lathes, drill presses, and CNC machining centers where compact tool projection is required. Maximum drilling depth is 0.350 inches.

Key Features

• Solid carbide K40 grade construction for rigidity and wear resistance
• 118-degree faceted point with web thinning for accurate entry and reduced thrust force
• Two spiral flutes with 3xD ratio provide efficient chip evacuation in shallow holes
• Stub (screw machine) length minimizes deflection on short-reach setups
• Straight-cylindrical shank fits standard drill chucks and collets
• Meets DIN 6539 specification for consistent dimensional accuracy

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for screw machine, lathe, drill press, and CNC machining center applications requiring a 0.082-inch diameter stub-length carbide drill bit per DIN 6539.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Secure the shank fully within the chuck or collet to the recommended grip depth before applying cutting loads. Ensure the spindle and workpiece are properly fixtured and all guards are in place before operation. Do not exceed the maximum drilling depth of 0.350 inches for this tool length.
