Guhring 9007320021000 Carbide Jobber Drill Bit 2.1mm

Product Description

The GUHRING 9007320021000 is a solid carbide jobber-length drill bit designed for precision drilling in general-purpose and non-ferrous metal applications. It features a 2.1 mm diameter (0.0827 inches), a 118-degree faceted drill point, and a right-hand spiral flute geometry. The bit is web-thinned to reduce entry force and improve chip evacuation. With an overall length of 49 mm and a flute length of 24 mm, it suits benchtop drill presses, CNC machining centers, and handheld pneumatic drills where small-diameter precision is required. Machinists, tool-and-die techs, and CNC operators are the primary installers of this bit.

This drill bit is suited for drilling aluminum and other non-ferrous materials classified under material code N. The straight-cylindrical shank with an h8 diameter tolerance fits standard collet chucks and drill press keyless chucks without modification. The 5xD flute-to-diameter ratio and a maximum drilling depth of 20.85 mm (0.821 inches) make it appropriate for through-hole and blind-hole work in light-duty production or maintenance machining environments. It is offered as a single-piece unit, making it practical for replacement or tooling-out individual stations.

Key Features

• Solid carbide construction for rigidity and wear resistance in non-ferrous drilling
• 118-degree faceted drill point with web thinning for reduced thrust and cleaner entry
• Right-hand, regular-spiral, two-flute design promotes efficient chip clearing
• Bright uncoated finish suitable for aluminum and soft non-ferrous workpieces
• Straight-cylindrical shank at h8 tolerance for accurate chuck or collet fitment
• DIN specification designation for dimensional conformance

Compatibility

Designed as an OEM-style replacement or production tooling option for applications requiring a 2.1 mm solid carbide jobber-length drill bit with a straight-cylindrical shank, within the 2.00 mm to 3.00 mm drill bit size range.

Installation Notes

Installation and use should be performed by qualified machinists or CNC technicians familiar with small-diameter carbide tooling. Ensure the machine spindle and chuck or collet are powered off and fully stopped before bit changes. Carbide bits are brittle and should not be used in applications with excessive runout or unstable workholding, as lateral loading can cause fracture. Verify maximum RPM ratings of the drilling equipment are appropriate for the bit diameter and workpiece material before operation.
