CAELUM Extreme Ball Nose Rotary Burr 1⁄4" Shaft, Rubber

The Caelum Extreme Ball Nose Rotary Burr is a high-performance abrasive tool designed for use with die grinders and rotary tools that accept a 1/4-inch shank. The burr features a ball nose shape and is constructed with tungsten carbide abrasive, which the manufacturer claims is 100 times more durable than traditional abrasives. This construction allows for efficient material removal while preparing surfaces for final finishing. It is designed for use on soft materials such as wood and rubber. Typical applications include engraving, carving, hollowing, grooving, and enlarging holes. The tool is compatible with rotary tools from brands like Bosch, DeWalt, and Milwaukee that can accommodate a 1/4-inch shank. The 1/4-inch diameter shaft is suited for larger detail work. Proper use requires ensuring the shank is fully inserted into the tool's collet and clamped tightly, using a 1/4-inch collet or adjustable chuck.
