Milling tool and method of using same

A milling tool configured for use with a rotary driver, said milling tool comprising:

• a cylindrical torque transmission shaft having a threaded bore formed in a first end thereof for attaching to a threaded shaft of said rotary driver, and having a second end for supporting a cutting wheel thereon;
• a cylindrical sleeve which slidably receives the torque transmission shaft therein, wherein the torque transmission shaft is rotatably supported in the sleeve;
• a hood for attaching to the sleeve member, said hood comprising a cylindrical body portion, a flange extending radially outwardly from an end of said cylindrical body portion, and a substantially C-shaped collar attached to and extending outwardly from the flange in a direction opposite to the body portion;
• a fence which is adjustably attached to said hood and which is selectively slidably positionable thereon;
• a cutting wheel comprising a rotatable disc and a plurality of cutting bits respectively mounted on the disc, the cutting wheel attached to the second end of the torque transmission shaft for concurrent rotation therewith, wherein the cutting wheel is disposed inside the collar of the hood, and proximate the fence.

A method of trimming a weld seam from a fillet weld on a welded assembly formed from two inside angle plates, said method comprising the steps of:

• aligning a fence of a rotary milling tool with a vertical angle plate of said welded assembly, with a hood of said milling tool placed facing downwardly on a horizontal angle plate of said weld assembly;
• powering said milling tool to rotate a cutting wheel thereof;
• and
• slidably moving the milling tool along the weld seam while keeping the fence substantially in contact with the vertical angle plate and the hood substantially in contact with the horizontal angle plate.
