Guhring 9039360160000 Machine Tap M16x2.00 Cobalt

Product Description

The GUHRING 9039360160000 is a straight-flute machine tap designed for threading M16x2.00 Metric Coarse holes in production and maintenance machining environments. Built from cobalt high-speed steel and finished with a dual TiAlN/TiN coating, this tap delivers extended tool life in abrasive and hard materials. The modified bottoming chamfer allows threading closer to the bottom of blind holes than a standard plug or taper tap, making it well suited for tight-tolerance work. At 3.811 inches overall length with a 0.480-inch shank diameter, it mounts in standard tapping chucks and rigid holders used on CNC machines and manual knee mills alike. Licensed machinists and tool-and-die technicians are the primary installers.

This tap is intended for blind-hole threading and through-hole threading applications in abrasive materials and cast iron. The 6HX class of fit with D7/D8 thread limits produces a tolerance suitable for standard metric fastener assemblies. The right-hand thread direction and four-flute straight-flute geometry work best in controlled tapping cycles where chip evacuation and coolant delivery are managed externally, as this tap does not feature coolant-through capability. It fits production runs and repair work on ferrous components where dimensional accuracy and coating durability are priorities.

Key Features

• Cobalt HSS construction for elevated heat resistance in abrasive and cast iron materials
• Dual TiAlN/TiN coating extends wear life and reduces friction at the cutting edge
• Modified bottoming chamfer enables threading close to the bottom of blind holes
• 4-flute straight-flute geometry provides stable chip formation in ferrous workpieces
• 6HX class of fit with D7/D8 thread limits for precise Metric Coarse tolerance control
• Right-hand, M16x2.00 Metric Coarse thread form compatible with standard ISO metric fastener specs

Compatibility

Rated for blind-hole threading and through-hole threading in abrasive materials and cast iron. Fits standard tapping chucks and collet holders accepting a 0.480-inch shank diameter with a 0.360-inch square drive.

Installation Notes

Machine taps should be installed by qualified machinists following established tapping procedures for CNC or manual machine tools. Ensure the spindle is fully stopped and the workpiece is securely fixtured before tool changes. Use appropriate tapping fluid or cutting oil for cast iron and abrasive materials to preserve coating integrity and thread quality. Do not exceed the tool manufacturer's recommended tapping speed range for the workpiece material and tap size.
