Guhring 9006580021500 Cobalt Drill Bit 2.15mm Tin

Product Description

The GUHRING 9006580021500 is a cobalt jobber length drill bit designed for high-performance drilling in ferrous metals. The bit features a titanium nitride (TiN) coating over a cobalt substrate, providing increased surface hardness and extended tool life compared to standard high-speed steel. At 2.15 mm (0.0846 inch) diameter with a 130-degree split point and parabolic flute geometry, it is engineered for fast chip evacuation and reduced thrust in demanding production environments. Right-hand cut with a straight-cylindrical shank, it seats directly into standard drill chucks without adapters. Overall length is 2-3/32 inches.

This drill bit is suited for drilling cast iron and steel in both job shop and production machining applications. The parabolic flute design supports deeper hole penetration with efficient chip clearing, making it practical for repetitive drilling cycles on manual drill presses, CNC machining centers, and hand-held power tools. The Series 658 designation conforms to DIN 338 standards, a common specification used across industrial and maintenance machining environments. Maximum drilling depth is 0.94 inch (23.78 mm), appropriate for through-hole and blind-hole work within jobber length reach.

Key Features

• Cobalt construction with TiN coating for extended wear resistance in ferrous materials
• 130-degree point angle with web-thinned, tapered web for reduced entry force
• Parabolic flute geometry promotes fast chip evacuation at a 5xD flute-to-diameter ratio
• Right-hand cut, straight-cylindrical shank fits standard drill chucks directly
• Conforms to DIN 338 specification for consistent dimensional tolerancing
• Diameter tolerance held to -0.014 to 0.000 mm for precise hole sizing

Compatibility

Designed as a DIN 338-compliant jobber length drill bit for use in standard drill chucks accommodating a 0.0846-inch straight-cylindrical shank. Primary workpiece materials are cast iron and steel.

Installation Notes

Installation and use should be performed by a qualified machinist or maintenance technician. Secure the shank fully in the drill chuck and verify runout before beginning a drilling cycle. Power down and de-energize the machine tool before changing bits or adjusting fixtures. Do not exceed the rated maximum drilling depth of 0.94 inch per pass without retracting to clear chips.
