Cutting tools increasingly work with an interior cooling system. Manufacturing tool shanks for these systems is difficult because cooling channels with a high length-to-diameter ratio have to be drilled. For some variants, the tool designers even call for drilling of inclined holes. TBT Tiefbohrtechnik, a developer of “deep drilling” technology, reported it has devised a special tool to drill with single lip drills.
Tool Shanks with Interior Cooling for Deep Drilling
Tool shanks have become complex workpieces because the coolant must be optimally fed to the edges of drilling or milling tool.
