Guhring 9024630044000 Screw Machine Drill Bit 0.1732in

Product Description

The GUHRING 9024630044000 is a stub-length, solid carbide screw machine drill bit with a 0.1732-inch (4.40 mm) diameter, designed for high-precision drilling in production and machining environments. Built to DIN 6539 standards using K40-grade carbide, it features a 118-degree faceted point, web-thinned tip geometry, and a two-flute spiral configuration. The straight-cylindrical shank seats directly in standard drill chucks or collet systems. This bit is intended for machinists, tool-and-die technicians, and CNC operators who need consistent, repeatable hole quality in short-run and high-volume applications alike.

The 9024630044000 is suited for drilling aluminum and similarly machinable materials where tight tolerances and clean entry are required. Its stub (screw machine) length provides added rigidity compared to jobber-length bits, reducing deflection in shallow-to-moderate depth holes. The flute-by-diameter ratio of 3xD and a maximum drilling depth of 0.685 inches (17.40 mm) make it a practical choice for close-tolerance work on CNC machining centers, drill presses, and manual knee mills. The coated finish supports chip evacuation and tool life in general-purpose production settings.

Key Features

• Solid carbide K40-grade construction for rigidity and wear resistance
• 118-degree faceted drill point with web-thinned tip for reduced thrust and clean entry
• Stub (screw machine) length provides greater rigidity over jobber-length alternatives
• Two-flute regular spiral design promotes consistent chip clearance
• Straight-cylindrical shank compatible with standard chucks and collet holders
• Manufactured to DIN 6539 specification with a diameter tolerance of +0.000 to -0.010 mm

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide stub drill for general-purpose machining applications requiring a 4.40 mm (0.1732-inch) diameter bit in the DIN 6539 Series 2463 product family.

Installation Notes

Installation and use of carbide drill bits should be performed by qualified machinists familiar with proper speeds, feeds, and fixturing for the workpiece material. Secure the shank fully in a collet or drill chuck to the manufacturer-recommended engagement depth before operation. Inspect the cutting edges and point geometry for chips or damage before each use, as solid carbide is brittle and sensitive to side-loading. Always power down and de-energize the machine spindle before changing tooling.
