Appl. No.:

13/336116

Inventors:

Brady J. Groth - Shorewood IL, US

Assignee:

ROBERT BOSCH GMBH - Stuttgart
ROBERT BOSCH TOOL CORPORATION - Broadview IL

International Classification:

B23Q 9/02
B25H 1/10

US Classification:

83743

Abstract:

A tool assembly is provided with an integrated support fixture and assemblies for orienting the tool at different angles relative to a workpiece. A guide rail assembly is provided that defines a travel path for the tool slidably supported thereon. The support fixture is configured to support the tool assembly on a workpiece so that gravity can assist movement of the tool across the workpiece. The guide rail assembly is mounted on a miter plate that can be oriented at different miter angles relative to the support fixture. The tool may be supported on the guide rail assembly to permit pivoting of the tool perpendicular to the miter angle. Another assembly may be provided that permits pivoting of the guided rail assembly at an orthogonal angle.
