drilling tool with coolant redirection for residue-free chip removal

KOMET®  project management developed a new PCD drilling tool for drilling water and freeze plugs, which, thanks to its innovative chip spoilers, prevents chip build-up in components.

Engine blocks generally contain „water plugs“ or „freeze plugs“, which – in the event that the coolant freezes – prevent damage to the engine. The newly designed PCD drilling tool is particularly efficient, as the „chip spoilers“ are highly effective at preventing chip build-up in components. The key to this is the use of additive manufacturing by  KOMET®  , which makes it possible to construct highly intricate chip spoilers with optimised, curved cooling channels.

Although the chip space on a conventional drilling tool is open to the side and the front, the chip spoiler on every cutting edge covers the groove frontally and radially. That leaves only a narrow gap of a few tenths of a millimetre between the spoiler and the cutting edge of the tool, through which any chips produced can „run off“. The spoiler channel then guides them reliably out of the drill hole. That‘s how the new water-plug drilling tool can be used to prevent chips remaining in the drill hole.
