Milwaukee 1/2 in. Contact Arm Assembly
Model Number: 42-09-0260
The Milwaukee 42-09-0260 1/2 in. Contact Arm Assembly is a genuine OEM replacement part designed for use on Milwaukee 1/2 in. Bandfile tools, including the 6101 (serial codes 878D and 878E) and 6101-6 (serial codes 878E and 878F) corded 5.5 Amp Bandfiles. The contact arm is the metal arm that mounts to the bandfile head and carries the platen and shoe assembly which the abrasive belt rides against during operation. As the operator presses the running belt against the workpiece, the contact arm transfers the cutting force from the belt-platen interface back through the head, allowing controlled, precise material removal for weld dressing, deburring, polishing, finish grinding, and tight-radius metal finishing work that a standard belt sander cannot reach. Manufactured to Milwaukee's exact factory tolerances and pivot geometry, this OEM contact arm restores the proper belt-to-workpiece contact pressure and arm rigidity required for clean abrasive results after the original arm becomes bent, cracked, worn at the pivot, or damaged from impact.
Because Milwaukee Tool specifies replacement parts by both catalog number and serial number, always verify your tool's serial number against the official Milwaukee bandfile service parts diagram before ordering, since the 42-09-0260 covers multiple serial-code variants of the 6101 and 6101-6 bandfiles. The 42-09-0260 is the Figure 50 component on Milwaukee service bulletins 54-38-0828 and 54-38-0829 and works directly with the companion 42-09-0250 Tension Arm (Fig 49), which holds the idler wheel and maintains running tension on the abrasive belt. When replacing the contact arm assembly, Milwaukee recommends inspecting the tension arm, dust cover (42-92-1200), support rod (45-60-0450), and 1/2 in. platen (44-66-5518) for wear at the same time, since the head-assembly components share the same service life and damage to one component is often accompanied by wear elsewhere in the head. All companion parts are sold separately. Verify by serial number using Milwaukee's online parts lookup before ordering to confirm correct fitment for your specific bandfile.
