DrillMeister rozszerza asortyment o korpusy wierteł DMC dla zakresu średnic 20,1-25,9 mm
Iwaki, September 2021 — Tungaloy has added ten DMC-style exchangeable drill heads for 20.1 to 25.9 mm (.791″ to 1.020″) drill diameter range to its DrillMeister exchangeable head drill series.
DrillMeister exchangeable head drills are a super productive, accurate, and cost efficient drill series. A single drill body can hold five different styles of drill heads in diameters ranging from 6.0 mm to 25.9 mm (.236″ to 1.020″). The drill heads are available in general purpose DMP style, DMC for high precision holes, DMH with enhanced drill corner geometry for drilling thin walls, DMF with flat edges ideal for counterboring, and DMN for non-ferrous applications.
Engineered to create high quality holes, the DMC drill head features a self-centering chisel edge geometry for smooth and secure drill engagement into the material, this eliminates the need for pilot holes even for deep hole drilling operations. In addition, a double margin feature on the drill head periphery helps stabilize the drill movement during drilling processes, providing the hole with superior surface finish quality and straightness equivalent to solid carbide drills.
The DMC drill heads is available in AH9130, a dedicated PVD-coated grade for drilling. Extremely wear resistant, the grade demonstrates long and predictable tool life in carbon steel and alloy steel.
