Emuge Metric Fine Spiral Point 6HX Tolerance Tap GLT-1 Coated ( High Performance )
Emuge High Performance 6GX Tap
Spiral Point FOR THROUGH HOLES
Emuge's High performance GLT-1 coated tap offers superior performance over the standard NE2/NT2 range.
6HX - Between tolerances 6H (ISO2) and 6G (ISO3), and between 6G and 7G, there are also taps with tolerance 6HX and 6GX. “X” means the tolerance is outside the standard and is used for taps working with high strength or abrasive materials such as cast iron. These materials do not cause oversize problems so higher tolerance can be used in order to increase tool life. The tolerance width is equal between 6H and 6HX. Forming taps are usually produced with a 6HX or 6GX tolerance.
GLT-1 - Hard surface coating with anti-friction layer In a PVD process (500 °C) a coating thickness of 2-4 μm can be realised. The combination of a hard surface coating (approx. 3000 HV) with a top anti-friction layer yields decisive tool life advantages. Also, the chip flow can be improved.
