MAPAL UK says it has added laser-sintered indexable insert drills with diameters down to 9mm to its QTD drill range. It says it has used laser sintering – a form of 3D printing – in the production of the new drills. This allows a non-circular profile to be used for the cooling ducts, which its claimed increases coolant flow by up to 100% compared with conventional drills.
The new QTD drills are available in diameters from 9 to 12mm and are said to be suitable for high-precision automotive manufacturing operations.
