A new formulation for the manufacture of Widia/cemented carbide, which is manufactured exclusively in Germany by Contex Hartmetall Verschleißtechnik GmbH, has been accompanied by enormous improvements in working lives and cleaning times. With more than 20 years’ experience in this sector, Gerhard Warning GmbH is now offering a product innovation which enables longer working lives and also significantly reduces cleaning times, since adhesions of concrete residues are markedly reduced.
