Guhring 9006220060000 Cobalt Jobber Drill Bit 0.2362in

Product Description

The GUHRING 9006220060000 is a cobalt jobber length drill bit designed for high-performance drilling in demanding trade and industrial applications. Built to DIN 338 standards, this bit features a 130-degree split point with web thinning for clean entry and reduced thrust. The parabolic flute geometry promotes efficient chip evacuation, and the nitrided land coating adds surface hardness to extend tool life. At 3-21/32 inches overall length with a 2-1/4-inch flute length, this bit fits standard drill chucks with a 0.2362-inch straight-cylindrical shank. Intended for installation and maintenance professionals who require consistent hole quality in production or field conditions.

This drill bit is suited for right-hand drilling operations in aluminum, non-ferrous metals, and plastics, covering workpiece material codes K, N, and P. The parabolic flute and web-thinned point make it particularly effective in materials prone to chip packing or work hardening. Typical applications include fabrication shops, HVAC sheet metal work, electrical panel drilling, and plumbing rough-in tasks where a reliable, repeatable hole diameter is critical. The 5xD flute-to-diameter ratio supports drilling depths up to 1.89 inches without retracting for chip clearing.

Key Features

• 130-degree split point with web thinning reduces drill walk and entry burring
• Parabolic flute design promotes fast, efficient chip evacuation in gummy or stringy materials
• Nitrided land coating increases surface hardness and extends tool life between resharpening cycles
• Cobalt construction maintains cutting edge integrity at elevated temperatures
• DIN 338 specification ensures dimensional consistency and cross-brand holder compatibility
• Straight-cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as a DIN 338-compliant jobber length drill bit suitable for use in standard drill chucks, drill presses, and CNC spindles accepting a 0.2362-inch straight-cylindrical shank. Primary workpiece materials include aluminum, non-ferrous metals, and plastics (material codes K, N, P).

Installation Notes

Installation and use should be performed by a qualified tradesperson familiar with rotating cutting tool safety. Secure the shank fully in the chuck before operation and verify runout is within acceptable limits for the application. Power down and lock out the machine before changing bits or inspecting the cutting edge. Do not exceed the maximum drilling depth of 1.89 inches in a single pass without retracting to clear chips.
