    Abstract: The drill head (2) extends along a rotational axis (24) in the axial direction (22) and has a central area (6) on the front with first main cutting edges (26), an intermediate area (8) connecting thereto, and an outer area (10) in turn connecting thereto with second main cutting edges (30). The intermediate area (8) in this case expands in the axial direction (22) toward the outer area (10) and in particular forms an expanding conical shell. A centering effect is hereby achieved via the intermediate area (8).

    Abstract: A step drill bit can include a cutting head defining a longitudinal axis and multiple steps having different effective diameters. First and second cutting edges can be formed in the cutting head. The first cutting edge and the second cutting edge can be arranged such that the bit is asymmetric in a plane perpendicular to the longitudinal axis relative to a plane containing the longitudinal axis. The step drill bit can further include one or more flutes. Each flute can define a groove in the cutting head that extends along a helical path about the longitudinal axis. Each flute can have a variable helix angle such that the angle of the helix about the longitudinal axis changes at one or more points along the length of the flute.

    Abstract: A wood drill bit has a plurality of step sections where each step section has at least one flute that terminates in a cutting edge. The effective diameter of each of the plurality of step sections is different than the diameter of the other of the plurality of step sections such that a single bit may be used to bore holes in wood of different diameters.

    Abstract: A central drill insert has a bottom surface, a top surface, and a peripheral surface extending therebetween. At least three lead drill portions protrude outwards from the peripheral surface, each having a drill axis and a plurality of drill cutting edges. A secondary cutting edge is adjacent each lead drill portion, extending along the intersection of the top surface and the peripheral surface, transversely to the respective drill axis. Each secondary cutting edge is spaced apart from the associated drill cutting edges along the drill axis. A dovetail abutment flank is formed on the peripheral surface along the intersection of the top surface and the peripheral surface, extending from each one of the lead drill portions towards the secondary cutting edge associated with another lead drill portion. A cutting tool has an insert pocket for retaining the central drill insert with the operative drill axis aligned with the tool axis.

    Abstract: An adjustable drill is provided comprising a drill body having at least one face surface with a plurality of serrations provided therewith. The drill further has at least one cartridge having a cooperating plurality of second serrations, to be driven with the drill body when assembled therewith. The at least one cartridge includes at least one insert pocket, and at least one insert is releasably affixed in the insert pocket provided in the cartridge. In further examples, the adjustable drill may have a central cutting system in combination with the adjustable cartridge type system, wherein the central cutting system may be modular. There may also be provided a modular type of holder arrangement to provide flexibility to adapt the system for various applications.
