Sandvik Coromant is upgrading its range of tools for steel tapping operations with two updates to its solid round tools range. The company says that its next-generation CoroTap T200 and T300 spiral tapping tools for ISO P materials deliver improved process security, longer tool life and a reduced cost per component.

CoroTap T200 and T300 are suitable for ISO P1 and P2 steel workpiece materials, and can therefore help improve the machining of parts such as crankshafts, steering knuckles and general engineering components like housings and flanges.

The CoroTap T200 has a spiral point, with the T300 featuring a spiral flute. While the spiral point of the T200 is suited to the machining of through holes – where chips are pushed forward – the T300 caters for blind holes, where there is no exit hole and chips must be pulled backwards. As part of the upgrade, both tools have a new surface treatment, as well as improved edge rounding for better finishing inside the machined hole. An enhanced flute form also aids better overall performance.

As a result of these upgrades, Sandvik Coromant reports that manufacturers will benefit from improved process security with an increased resistance to edge chipping, leading to fewer tool breakages and enhanced thread quality. In addition, the cutting-speed capability is higher than with previous versions of the tool, subsequently leading to an overall reduction in the cost per part.

Another major difference compared with previous versions of the CoroTap range is that customers can benefit from Sandvik Coromant’s ‘Tailor Made’ web assortment. This service gives customers the freedom to specify their own dimensions, without paying for a specialist tool.
