Tungaloy Adds Self-Centering Drill Heads to DrillMeister Line

The Tungaloy range of DrillMeister indexable head drills has now been extended to include the latest DMC style drill head. The new DrillMeister DMC features a self-centering chisel edge profile with a new coating grade that has been designed to boost indexable drilling performance. 

The new drilling platform permits fast drill head indexing, thanks to an innovative self-clamping mechanism that eliminates the need to remove the drill body from the spindle for tool changeovers or the re-adjustment of the tool overhang. The fast indexing with high repeatability capabilities of the DrillMeister DMC significantly improve machine uptime and productivity. 

The new DMC drill head incorporates a centre-point chisel edge geometry that self-centres to provide accurate hole diameter and circularity. In addition, it features a double margin design that stabilises the drill during the drilling processes, improving hole surface finish, straightness and precision levels.  

The DrillMeister DMC is available with Tungaloy’s AH9130 insert grade, which incorporates a next generation coating that has been specifically engineered for drilling applications. The AH9130 insert grade features a Nano-scale structure multi-layered coating that is applied with three primary layers. This new coating technology provides an optimal combination of resistance to physical and chemical stresses such as wear, fracture, oxidation, built-up edges and de-lamination. By eradicating these common issues, the DrillMeister DMC guarantees exceptionally long and consistent tool life under the most challenging of applications. 

The ingenious new DrillMeister DMC drill head is available in diameters from 10mm to 19.9mm in increments of 0.1mm whilst its double margin drill head geometry ensures improved surface finish and precision levels without the need for pre-spotting or pecking cycles. The self-centering geometry of the DMC ensures that the expansive DrillMeister line can outperform competitor drilling products when conducting holemaking operations up to 12xD. With a total of 100 items to be added to this series, the comprehensive holemaking range from Tungaloy is certainly worth investigating.
