Guhring 9024630034500 Stub Drill Bit 0.136 in Solid Carbide

Product Description

The GUHRING 9024630034500 is a stub-length (screw machine length) solid carbide drill bit designed for precision drilling in production and machining environments. Built to DIN 6539 standards, this bit features a 118-degree faceted point angle, two spiral flutes with web thinning, and a straight-cylindrical shank. At 0.136 inches (No. 29 wire gauge) in diameter and 2.047 inches overall length, it delivers tight-tolerance hole-making in compact setups. The K40 carbide grade and coated finish support consistent performance across high-cycle applications where tool life and hole quality are critical.

This drill bit is suited for machining aluminum and other non-ferrous materials in CNC drill presses, machining centers, and screw machine operations. The stub flute length of 0.787 inches and maximum drilling depth of 0.584 inches make it well matched to shallow-hole work where rigidity and runout control matter. The 3xD flute-to-diameter ratio supports chip evacuation in short-depth bores. Machinists, tool-and-die technicians, and production shop operators are the typical end users.

Key Features

• Solid carbide K40 grade construction for wear resistance in aluminum and non-ferrous materials
• 118-degree faceted point with web thinning for clean entry and reduced thrust force
• Stub (screw machine) length body at 2.047 inches overall for increased rigidity in tight setups
• Two spiral flutes with regular spiral type for efficient chip removal in shallow bores
• Straight-cylindrical shank at 3.45 mm diameter for standard chuck and collet compatibility
• Built to DIN 6539 specification with diameter tolerance of +0.000 to -0.010 mm

Compatibility

Designed as an OEM-style replacement or direct-use stub drill bit for machining operations requiring a No. 29 wire gauge (0.136 inch) diameter hole in aluminum and similar workpiece materials per DIN 6539 specification.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with drill press, CNC, or screw machine setup. Secure the straight-cylindrical shank firmly in a properly sized collet or drill chuck before operation and verify runout before beginning a production run. Power down and de-energize the machine fully before changing or inspecting tooling. Do not exceed the maximum drilling depth of 0.584 inches without retracting for chip clearance.
