CoroTap® 400

Long tool life reduces costs

Solid taps are made of high-speed steel with cobalt, high-speed powder steel, carbide or tungsten for superior wear resistance and tool life, resulting in fewer machine stoppages and reduced cost-per-hole.

Superior process security

Optimized lobe profiles allow for reliable, predictable tool life at high cutting speeds for both through and blind holes.

Excellent thread quality

To ensure low friction at high speeds for precision thread forming with minimal surface roughness, there are five coatings available: TiCN, TiN, TiNF, CrN, and Bright (uncoated).
