Emuge - M4x0.70 Metric 6H Modified Bottoming Thread Forming Tap

Modified bottoming chamfers are similar to bottoming chamfers, but they are longer and have more teeth. They are used for threading to the bottom of blind holes and have 2 to 2-1/2 threads.

GLT-8 coatings are diamond-like coatings and provide a hard surface for good thermal protection as well as high surface lubricity. Ideal for machining nonferrous materials and aluminum. GLT-8 is a proprietary coating exclusive to Emuge.

Powdered Metal (PM) is tougher and more cost effective than solid carbide. It is commonly used on highly abrasive materials including high silicon aluminums.
