MAPAL claims it has developed a new drill optimised to overcome the challenges of thermoplastics drilling. The Mono-Plastic-Drill is suited for use with PEEK, POM or PA 6, as well as other materials with low thermal conductivity and low melting temperature that make machining difficult.
The company says the drill has been designed with special properties, including an extremely sharp blade and special point thinning. As a result, bore tolerances up to IT7 are achieved. To optimally dissipate the heat via the chips, the drill is made of uncoated solid carbide and has a large, polished chip flute.
In addition the Mono-Plastic-Drill can also be used to machine aluminium parts and is available with a diameter range of 0.97 to 13.03mm and lengths of up to five times its diameter.
