Emuge’s JIS line of high-performance taps is designed for Japanese-specified standards. Shank diameter and square dimensions are in accordance with those standards, and the taps are designed to produce threads with a JIS Class 2 tolerance.
A variety of tap geometries and styles produce threads in a range of materials including steel, stainless steel, cast iron, nonferrous materials, titanium, titanium alloys, nickel, nickel-based alloys and cobalt-based alloys. Tap surfaces are treated with titanium carbonitride or a titanium nitride coating to increase tool life. For efficient chip evacuation and maximum lubrication, the taps also are available with an internal coolant-lubricant supply exiting through the tap or in the flutes.
The taps are offered in designs for both short-chipping and long-chipping material, and through- or blind-hole applications. The line also includes a tap designed to produce threads in cast iron, as well as abrasive cast iron with vermicular graphite. The taps are optimized for use on automatic lathes, multi-spindle machines or CNC machines. Cold-forming taps for the chipless production of internal threads in blind- or through-holes also are available.

The taps range in size from M 5 × 0.8 to M 12 × 1.75 in metric coarse and from M 10 × 1.25 to M 20 × 1.5 in metric fine, straight-flute, spiral point, slow- and fast-spiral flute configurations.
