  • Patent number: 10471521
    Abstract: The present invention is concerned with twist drills for drilling of composite materials such as carbon fibre reinforced plastic (CFRP) and glass fibre reinforced plastic (GFRP). The present invention proposes that a twist drill (2) is provided with a variable helix having a defined start and finish helix angle, in combination with primary and secondary relief angles such that the drill (2) is adapted to minimise thrust force, particularly when used for drilling fibre-containing composite materials and especially for hand drilling. Start and finish helix angles of 50° and 10°; 50° and 30°; and 30° and 10° have been shown to provide excellent cutting performance and exit hole quality. A large secondary chisel edge angle (24) has also been found to contribute to excellent performance with composite materials, including stack machining.

  • Patent number: 10464178
    Abstract: A docking assembly for docking and retrieving a filament holding device includes a motor casing rod defining a recess, filament holders and docking stations. Each filament holder defines a filament receiver channel for receiving the rod and a stop member that is selectively engaged with the recess of the rod, thus coupling a filament holder to the rod for retrieval of the filament holder. Each docking station includes a deployment latch operable to rotate when the rod is inserted into the docking receiver channel so that the deployment latch urges the stop member to the deployed configuration for coupling together the rod and the filament holder. Thus, a filament holder is captured for removal from the docking station. The docking apparatus includes a release lever that operates in reverse of the deployment latch so as to release a filament holder from the rod back to its docking station.
