Guhring 9007320049800 Jobber Drill Bit No.9 Solid Carbide

Product Description

The GUHRING 9007320049800 is a solid carbide jobber length drill bit sized to No. 9 wire gauge, equivalent to 0.1961 inch diameter. It features a 118-degree faceted point angle with web thinning for improved centering and reduced thrust on entry. The spiral flute geometry and bright uncoated finish suit general-purpose drilling in non-ferrous materials. Overall length is 86 millimeters with a flute length of 52 millimeters and a straight-cylindrical shank. This bit is part of the Guhring Series 732 and is manufactured to DIN specification with an h8 diameter tolerance. It is installed and used by machinists, tool-and-die tradespeople, and maintenance technicians working with precision drilling applications.

This drill bit is rated for primary use in aluminum and other non-ferrous workpiece materials, designated by material code N. The 5xD flute-to-diameter ratio and regular spiral type make it well suited for through-hole and blind-hole drilling in production and maintenance environments. The straight-cylindrical shank is compatible with standard drill chucks and collet holders accepting a 4.98 millimeter shank diameter. Maximum drilling depth is 44.53 millimeters. Coolant-through capability is not included in this configuration.

Compatibility

Designed as a general-purpose OEM-style replacement drill bit compatible with standard drill chucks and collet holders accepting a straight-cylindrical shank of 4.98 millimeters, suitable for use in CNC machining centers, drill presses, and hand-held drilling equipment.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or trade technicians familiar with cutting tool setup and safe machine operation. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Secure the shank fully within the chuck or collet to the recommended engagement depth before operation. Do not exceed the rated maximum drilling depth of 44.53 millimeters per pass without retracting to clear chips.
