摘要： The invention relates to a stop for a rotating drilling, milling or countersinking tool which comprises a stop sleeve which is freely rotatably coupled, by means of a sliding or rolling bearing, around the tool. A first bearing bush of the bearing supports the stop sleeve. A second bearing bush of the bearing sits in a rotationally fixed manner on a shaft sleeve. The shaft sleeve can be pushed and fastened on a shaft of the tool. In a secondary aspect, the invention relates to a drilling, milling or countersinking tool having such a stop.

摘要： A positioning sleeve assembly adapted for engaging with drill bit holder or screwdriver bit is provided with a sleeve and an engaging device. The engaging device includes a drive shaft at one end and an inserting hole at another end. The engaging device is inserted in the sleeve with the drive shaft located one end of the sleeve, and the inserting hole at the other end of the sleeve. The inserting hole at one end of the engaging device is suitable for both engaging with a drill bit holder and a screwdriver bit, so that a single positioning sleeve assembly of the present invention is capable of selectively connecting drill bit and screwdriver bit.

摘要： A template for use with an instrument to drill a hole in a surface at a desired location. The template includes a body which has a negative impression of the surface, and a guideway having a first end positioned to open onto the desired location when the body is placed in conforming contact with the surface and a second end positioned on an exterior surface of the body. The second end of the guideway is connected to the first end by a passage. The guideway is preferably positioned in a portion of the template which is removable from the remainder thereof. The template also includes a stop for limiting the depth of penetration of the drill bit into the hole, a first fastener for attaching the stop to the body and a second fastener for fastening the removable portion of the template to the remainder of the template.
