Guhring 9046290160000 Spiral Flute Tap M16x2.00 Left Hand

Product Description

The GUHRING 9046290160000 is a spiral flute tap designed for blind hole threading in a wide range of materials, including steel, stainless steel, cast iron, aluminum, and nickel titanium alloy. Built to a 6HX class of fit with a D9/D10 thread limit, this M16x2.00 metric tap produces left-hand internal threads to precise tolerances. The TiAlN coating increases surface hardness and heat resistance, extending tool life in demanding cutting conditions. With a 45-degree helix angle and four left-hand spiral flutes, the tap efficiently evacuates chips up and out of the hole during blind hole operations.

This tap is suited for production and maintenance machining environments where left-hand threaded blind holes are required in ferrous and non-ferrous materials. The semi-bottoming chamfer allows threading close to the bottom of a blind bore, making it appropriate for applications where thread depth relative to hole depth is critical. Series 4629 from GUHRING targets professional machinists and toolroom technicians working in aerospace, automotive, general manufacturing, and similar industries requiring tight-tolerance metric threading.

Key Features

• M16x2.00 left-hand metric thread, 6HX class of fit with D9/D10 thread limit
• Semi-bottoming chamfer for threading near the bottom of blind holes
• 45-degree left-hand spiral flutes for upward chip evacuation in blind hole applications
• TiAlN coating for improved heat resistance and extended tool life
• Compatible with aluminum, cast iron, steel, stainless steel, and nickel titanium alloy
• No coolant-through design; standard external coolant or cutting fluid applies

Compatibility

Designed for blind hole threading applications requiring M16x2.00 left-hand metric threads; compatible with aluminum, cast iron, nickel titanium alloy, stainless steel, and steel workpiece materials per manufacturer specification.

Installation Notes

Installation and use should be performed by qualified machinists familiar with tapping operations and cutting tool safety. Ensure the workpiece is securely fixtured and the spindle is properly aligned before engaging the tap. Use appropriate cutting fluid or tapping compound for the workpiece material to reduce friction and heat buildup. Inspect the tap for wear or damage before each use, and never force a tap that has stalled in the bore.
