Guhring 9007320028700 Jobber Drill Bit 33 Solid Carbide

Product Description

The GUHRING 9007320028700 is a jobber-length, solid carbide drill bit designed for general-purpose drilling in a production or maintenance environment. Built to DIN specification in Series 732, it carries a wire gauge size of 33 (0.1130 inch decimal) and features a 118-degree faceted point with web thinning for clean entry and reduced thrust. The two-flute spiral design promotes chip evacuation, and the bright uncoated finish suits applications where coating adhesion or heat buildup is not a primary concern. Overall length is 61 millimeters with a flute length of 33 millimeters.

This drill bit is rated for general-purpose use with a primary workpiece material designation of aluminum and non-ferrous materials (material code N). The straight cylindrical shank measures 2.87 millimeters in diameter and seats directly in standard collets and drill chucks without adapters. Typical install scenarios include precision hole-making on light-gauge metal components, circuit board substrates, and similar materials where tight diameter tolerance (h8) is required. The 5xD flute-to-diameter ratio supports moderate drilling depths up to 28.70 millimeters.

Key Features

• Wire gauge size 33 (0.1130 inch) with h8 diameter tolerance for consistent hole sizing
• 118-degree faceted point with web thinning for reduced entry thrust and improved centering
• Two-flute regular spiral geometry promotes chip clearance in non-ferrous and soft materials
• Solid carbide construction for rigidity and wear resistance at higher spindle speeds
• Bright uncoated finish — no coating to flake or delaminate during regrinding
• DIN-specification Series 732 design for standardized fitment in tooling systems

Compatibility

Designed as an OEM-style general-purpose jobber-length drill for use in standard drill chucks and collet systems accepting a 2.87-millimeter straight cylindrical shank, suited for aluminum and non-ferrous workpiece materials.

Installation Notes

Installation and use should be performed by a machinist or qualified tooling technician. Secure the straight cylindrical shank fully in a properly sized collet or drill chuck before operation and verify runout is within acceptable limits. Power down and de-energize the machine spindle completely before changing or inspecting the bit. Do not exceed the maximum drilling depth of 28.70 millimeters, and apply appropriate cutting fluid or air blast as required by the workpiece material and shop practice.
