摘要： A pocket hole jig includes base with a base plate and first and second lateral side walls extending along the base plate, and a body disposed between the first and second lateral side walls and slidable along the base in a forward direction and a rearward direction. The body includes a drill bit aperture angled downward toward the base plate. The pocket hole jig also includes a fence movable between a raised position and a lowered position and having a contact surface engageable with an end of the workpiece when the fence is in the lowered position to position the base a predetermined distance from the end of the workpiece. The contact surface is in a first position when the fence is in the raised position and a second position when the fence is in the lowered position. The second position is forward of the first position.

摘要： The invention relates to an improved dental tool drive arrangement for a handpiece with a drive head, the tool drive arrangement permitting length adjustment of the tool in the drive head by concentrically supporting the tool in the drive head at any position from a fully inserted position to a maximum retracted position. The tool drive arrangement preferably includes a tool and a rotatable tool supporting element for concentrically supporting the tool from the fully inserted to the maximum retracted position, the tool preferably including a maximum retraction indicator for indicating to a user when the tool has been retracted to the maximum retraction position. This provides a significant advantage over the prior art by allowing a user to adjust the exposed length of a rotatable tool, preferably a dental bur, without exceeding safe operating limits. The invention also relates to an improved drive spindle which allows depth adjustment of a tool in a dental handpiece while maintaining efficient torque transfer and concentricity during high speed rotation.

摘要： There are disclosed herein power tool boring bits having boring depth indicating markings on the shanks thereof. The markings are produced by colored oxiding of substantially the entire shank of the tool followed by selective abrasion of the shank to remove bands of substantially only the thin surface oxide in alternate array with bands of the colored oxide.
