Guhring 9006510003300 Jobber Drill 81 Wire Hss Tin

Product Description

The GUHRING 9006510003300 is a high speed steel jobber-length drill bit in size 81 wire gauge (0.0130 inch diameter), finished with a titanium nitride (TiN) coating for improved wear resistance and surface hardness. It features a 118-degree cone relief point, a web-thinned tip for reduced thrust during entry, and a two-flute regular spiral configuration with a straight-cylindrical shank. Overall length is 19.00 mm with a flute length of 4.00 mm. Built to DIN 338 standards, this bit is suited for general-purpose drilling in cast iron and steel at production and maintenance environments where small-diameter precision holes are required.

This drill bit is intended for use in precision drilling applications requiring wire gauge sizing in ferrous materials, including cast iron and steel substrates. The h8 shank diameter tolerance ensures consistent fit in standard chucks and collets. The 5xD flute-to-diameter ratio and web-thinned point make it appropriate for short, controlled hole depths in light production drilling, tool room work, and maintenance repair operations. It is sold individually and is part of the GUHRING Series 651 program.

Key Features

• Size 81 wire gauge — 0.0130 inch diameter with h8 shank tolerance for repeatable chuck fit
• 118-degree cone relief point with web thinning for reduced entry thrust
• Titanium nitride (TiN) coating extends tool life on cast iron and steel
• Two-flute regular spiral design provides reliable chip evacuation in short-depth holes
• Straight-cylindrical shank compatible with standard drill chucks and collets
• Conforms to DIN 338 specification for jobber-length drill geometry

Compatibility

Designed as an OEM-style general-purpose jobber drill for use in standard drill chucks, CNC machining centers, and benchtop drill presses where wire gauge 81 diameter holes are required in cast iron or steel workpieces.

Installation Notes

Installation and use should be performed by a qualified machinist or tooling technician. Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable limits for the application. Power down and de-energize all equipment before changing tooling. Do not exceed the maximum drilling depth of 3.51 mm (0.138 inch) without retracting to clear chips.
