A throwaway drill, an insert provided on the throwaway drill, and a cutting method using the same. The throwaway drill has a throwaway drill holder including an inner edge insert pocket having a seat, formed on a central axis side of a tip end of a drill main body, and an outer edge insert pocket having a seat, formed on the outer peripheral side of the tip end; an inner edge insert fixed to the seat of the inner edge insert pocket; and an outer edge insert fixed to the seat of the outer edge insert pocket. When viewed from the tip end side of the drill main body, the inner cutting edge of the inner edge insert includes: a first inner cutting edge provided on the central axis side of the drill main body, being parallel to at least part of the outer cutting edge of the outer edge insert; and a second inner cutting edge provided on the outer peripheral side of the drill main body, being inclined to the seat of the inner edge insert pocket in a direction toward the outer peripheral side, with respect to the first inner cutting edge.

The present disclosure provides exemplary collapsible drills and associated methods of use. Thus, in one aspect, the disclosure provides a collapsible drill including or comprising a chuck, a piston and a motor section. The chuck can be configured and dimensioned to receive a drill bit. The piston can include a pair of interlocking splines. The motor section drives rotation of the piston and the chuck. Depression of the piston can stop rotation of the chuck relative to the piston. In another aspect, the disclosure provides methods of drilling into a material that include providing a collapsible drill, driving rotation of the piston and the chuck with the motor section, and depressing the piston to stop rotation of the chuck relative to the piston.

Described is a quick-change arbor for a tool, in particular a hole saw (2), the arbor comprising a longitudinal body (3) having a drive end and a tool end, means (6) for attaching the tool which are provided with a central hole allowing a sliding of the attachment means (6) over the longitudinal body (3), and means for rotationally and axially locking the attachment means (6) to the longitudinal body (3). The attachment means (6) are slidably releasable from the longitudinal body (3), and can after applying a latch (9-1) in the attachment means (6) simply be slid over the body in order to push a plug of the sawn material out of the hole saw (2).
