Guhring 9006220033000 Cobalt Jobber Drill Bit 3.3 Mm

Product Description

The GUHRING 9006220033000 is a cobalt jobber length drill bit engineered for high-performance drilling in demanding trade and production environments. Sized at 3.3 mm (0.1299 inches decimal equivalent), it features a 130-degree split point with web thinning for self-centering entry and reduced thrust. The parabolic flute geometry promotes efficient chip evacuation, which is especially important when drilling non-ferrous metals and softer alloys. With an overall length of 2-9/16 inches and a straight-cylindrical shank, this bit fits standard drill chucks and CNC toolholders. It carries a bright, uncoated finish and conforms to DIN 338 standards. Machinists, tool-and-die technicians, and general fabrication pros reach for this bit when accuracy and tool life in small-diameter work matter.

This drill bit is rated for primary use in aluminum and other non-ferrous and general-purpose workpiece materials (material codes K, N, and P). Its 5xD flute-to-diameter ratio and maximum drilling depth of 1.222 inches (31.05 mm) make it well suited for through-hole and moderate-depth blind-hole applications on machining centers, drill presses, and hand-held electric drills. The two-flute, parabolic design handles chip clearance without packing in softer materials. Series 622 is a Guhring production-grade jobber line built for consistent, repeatable hole sizing in light manufacturing and maintenance-repair operations.

Key Features

• 130-degree standard point with web thinning for self-centering and reduced entry force
• Parabolic two-flute design for efficient chip evacuation at depth
• Straight-cylindrical shank (0.1299 inches) fits standard chucks and collets without modification
• Conforms to DIN 338 specification for consistent dimensional accuracy
• Bright, uncoated finish — no coating buildup concerns when regrinding

Compatibility

Designed as an OEM-style jobber length drill bit conforming to DIN 338, suitable for use in standard drill chucks, collet holders, and CNC spindles accepting a 0.1299-inch straight shank across a wide range of drilling equipment.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or maintenance technicians familiar with cutting tool setup and machine operation. Ensure the drill chuck or collet is properly tightened and the shank is fully seated before operation. Inspect the cutting edge for wear or damage before each use, and never operate at feeds or speeds outside the recommended range for the workpiece material. Secure the workpiece firmly to prevent movement during drilling.
