Indexable insert drills – no compromise performance in small diameters

MAPAL has addressed this problem in its latest QTD products, which are ideal for high-precision automotive and aerospace manufacturing operations, by using 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 increases coolant flow by up to 100% compared with conventional drills that have a central cooling duct with diversions.

“The form of the cooling ducts in our new small diameter QTD drills allows optimum coolant flow to be achieved without impairing the performance of the tool or making it unstable,” said Wayne Whitehouse, Managing Director of MAPAL UK. “In fact, our new QTD indexable insert drills are unique and they offer so many benefits that they are the subject of a patent. Once again, we’re providing our users with a better, more cost-effective way to reliably achieve the results they need.”

MAPAL’s new QTD drills are available in diameters from 9 to 12 mm and are usually available from stock for immediate delivery. Larger diameter drills in the QTD range, from 13 mm upward continue to be available and, because they have more space to accommodate the cooling duct, they feature conventional coolant supply arrangements.
