Tungaloy (Iwaki, Japan) has expanded its popular DrillMeister range of exchangeable-head drills to include the new, DMH drill head with enhanced cutting-edge geometry.
DrillMeister incorporates a self-locking interface that enables simple and secure drill head exchange. Since drill heads can be replaced without having to remove the drill body from the spindle tool, setup time can significantly be reduced, eliminating presetting, offset and touch off of the replaced tool.
To address issues that inflicts severe impact and damage on drill corners and result in short, unstable tool life, Tungaloy’s DMH drill head features a robust edge geometry that is designed specifically to protect the drill corners from fracture damage, while ensuring tool life predictability and good chip control.
The DMH drill head is available in grade AH9130 to provide the drill with a good balance of wear and fracture resistance.
