Geometric freedom for complex insert drills

QTD insert drill with new cooling duct profiles, which deviate from the usual circular shape with a slightly triangular shape. That optimises the geometrical moment of inertia and the flow rate. Tests found that choosing a cross section of this type increases the flow quantity by 30%. Coolant profiles like this cannot be produced conventionally. (Source: Mapal) arrow forward Image Zoom
