In an example, a clamp foot for a clamp assembly includes a housing having a distal end for engaging a workpiece, an aperture in the distal end of the housing, and a cavity in the housing extending proximally from the aperture. The clamp foot also includes a flapper in the cavity and adjacent to the distal end. The clamp foot further includes a pneumatic port in the cavity configured to direct a pneumatic force from a pneumatic source to the flapper, and a vacuum port in the cavity for coupling the cavity to a vacuum source. Responsive to the pneumatic force, the flapper is movable within the cavity to separate debris from the workpiece. The vacuum port is configured to remove from the cavity, via a vacuum force from the vacuum source, the debris separated from the workpiece by the flapper.

A drilling end effector may include a motor operative to drive a drilling member, a housing surrounding the motor, and a vacuum shroud coupled to the housing and surrounding the drilling member, wherein the vacuum shroud has a variable length.

A debris collecting rotary tool attachment for collecting debris during rotary tool use includes a shell that comprises a wall. The wall extends from a top to a bottom of the shell and has an inner face. The inner face is tackified, such that the inner face is configured to sequester debris on the inner face of the shell. The top and the bottom are open, defining respective perimeters. A fastener is coupled to the bottom and extends around the perimeter of the bottom. The fastener is configured to sealably couple the shell to a chuck end of a rotary tool. The shell is positioned around a cutting tool secured in the chuck of the rotary tool. The inner face is tackified to sequester debris generated during operation of the rotary tool.

A drilling byproduct recovery system employs a vacuum shroud positioned adjacent a workpiece. A spindle extends from a base and engages a tool. The spindle vertically reciprocates the tool upwardly through an aperture in the vacuum shroud to engage the workpiece. A circumferential air jet is emitted proximate a base of the spindle and directed toward the vacuum shroud.

A hole cutter assembly is operable to cut a plurality of different sized diameter holes in a work piece. The hole cutter assembly includes an arbor configured to connect to a power tool for rotation about an axis, and a body coupled to the arbor for rotation with the arbor. The body defines an aperture. The hole cutter assembly includes a drill bit removably received in the aperture of the body for rotation with the arbor, an arm moveably coupled to the body, and a cutting blade coupled to the arm and moveable with the arm relative to the body. The arm is moveable relative to the body to adjust a cutting diameter of the hole cutter assembly when the drill bit is not received within the aperture. The arm is fixed relative to the body when the drill bit is received within the aperture.

A cutting machine waste extraction apparatus is provided for a cutting machine that cuts a plate where the cutting machine waste extraction apparatus is supported adjacent a cutting area at a cutting table. The cutting machine produces waste at the cutting area during the cutting of the plate where the apparatus includes a ducting system having a first duct that receives the waste from the plate, and a second duct that receives the waste from the first duct. The first duct is movable along the length of the second duct and the second duct includes a lengthwise opening which is sealed by a flexible belt. The flexible belt is deformable from sealed contact with the second duct, adjacent a junction apparatus, where the junction apparatus provides a fluid connection between the first duct and the second duct.

A drilling head for a tubular shank having an inside diameter and threads may comprise an axial body comprising a duct exiting through a first end; threads adjacent the first end corresponding to the threads on the shank and aligning the duct with the shank inside diameter; a bore from an outer surface of the body to the duct; and two axially extending approximately parallel and offset surfaces adjacent a second end; and an insert affixed between the offset surfaces, the insert comprising: a first face at least partially contacting one offset surface and a second face at least partially contacting the other offset surface; one or more cutting edges adjacent the first face, the second face, or both; and a cutting lip adjacent one or more cutting edges.

A power tool includes a drilling tool and a dust collector configured to be removably attached to the drilling tool. The dust collector includes a dust collector body, a passage part provided in the dust collector body and having elasticity, and a storing part configured to be removably attached to the dust collector body and to store dust. The passage part includes a drilling tool mounting port part configured to be connected to the drilling tool while pressing a specified region of the drilling tool, and a storing part mounting port part configured to be connected to the storing part while pressing a specified region of the storing part. Air containing the dust is led through the dust collector body to the storing part, and the air from which the dust has been separated in the storing part is led through the passage part into the drilling tool.
