Abstract: There is provided a drill tool assembly for drilling metallic or other materials, comprising a holder having a mounting slot in which a cutting insert is positioned, and a through tool coolant supply system. The drilling tool system allows for the application of coolant to the rake surfaces of the cutting insert in a manner which facilitates enabling higher penetration rates while maintaining integrity of the cutting edges of the cutting insert. The drilling tool system comprises a holder having a rotational axis and mounting slot. A cutting insert with sides positioned adjacent the side surfaces of the mounting slot and cutting edges extending from the rotational axis is mounted in the slot. The insert includes rake surfaces adjacent the cutting edges that are positioned above the mounting slot. At least one coolant channel is disposed with at least one coolant outlet directed at the sides of the insert at a position below the rake surfaces.

Abstract: A vacuum drilling system and methods is provided that may utilize both a through tool coolant supply as well as a central vacuum extraction system. The system may include a cutting head provided on a hollow tube and a vacuum source to apply vacuum pressure to the area of the cutting head via one or more chip inlets arranged proximate to the cutting head. Sealed coolant containment channels supply coolant to the area of the cutting head.
