Micro-drilling service from Mollart

The expansion of its successful deep hole and added value service encompasses a precision micro-drilling and ultra-thin wall hole component production service for holes as fine as 0.5 mm diameter by up to 50 mm deep. The service, which stretches the current boundaries of hole machining technology, can be applied to materials as diverse as plastics to challenging materials such as titanium and high alloy steels. “To achieve this level of expertise we drew together our machine tool building, deep hole tooling development, materials knowledge and application skills so we are able to provide a fast turn around for customers,” said managing director, Guy Mollart. Examples of the company’s work include a special titanium screw for brain surgery for an American medical customer. This is used to support and guide an inspection probe into the skull of a patient. The diameter of the bore is just 0.81 mm and the hole is 35 mm deep. In another example, equine dental drills for use by vets on horses (pictured) made from 316 stainless steel with a central cooling hole of 1 mm diameter are drilled depth is 24 mm. This hole breaks into three straight flutes behind the tool point that are ground by Mollart to precisely create the cutting edge geometry.
