Sheffield-based WNT (UK) (www.wnt.com) has extended its Restart tool-regrinding service to cover virtually all of the HSS and solid-carbide drills and end mills — along with the PCD and CBN-tipped indexable-insert tools — in its product range.

This service returns the tools to their original geometry, ensuring optimum performance. In order to maximise the longevity of the cutters, WNT works on the principle of removing as little material as possible when regrinding.

When a company asks to use the Restart service, WNT despatches a regrind box, a delivery note and a courier returns label.

Once the tools have been packed in the box, they are picked up by courier and sent to WNT for inspection. As soon as the box is received, a second box is despatched, so that the customer can start collecting the next batch.

To ease recognition, the reground tools are etched accordingly. Any cutters deemed to be beyond economical regrind will not be ground and will be returned to the customer.

Managing director Tony Pennington says: “The Restart service is available on a wide range of tools, and customers have the reassurance of their cutters being serviced by the people that manufactured them — to the original geometry and with the original tool coating re-applied.

"The Restart service is another example of how WNT is working with its customers to drive down manufacturing costs by extending the life of existing cutters and delaying the requirement to buy new.”
