Dormer Tools introduces Shark Line taps

#MACH2014 Is there a need for material specific taps? Yes, says Dormer Tools (Sheffield) Ltd (www.dormertools.com), which has introduced Shark Line taps. These feature a coloured ring that indicates which specific material type each tap is suited to. They are available in spiral point for through-hole applications, spiral flute for threading blind holes and, in the case of white ring taps for cast iron, straight flute for both through or blind holes (Hall 5 Stand 5248).

Shark Line taps are manufactured from an HSS-E-PM substrate specifically developed to give the additional toughness required and a ‘grindability’ superior to conventional high-speed steels. Extra-fine surfaces due to improved grinding technology allow the advanced surface coating to have a smoother finish. This reduces the risk of chipping, increases tool life and allows higher cutting speeds.
