Dremel EZ456B 1 1/2-Inch EZ Lock Rotary Tool Cut-Off Wheels- Rotary Tool Cutting Accessories, Perfect for Slicing Sheet Metal and Copper Pipe, 12 Pieces

The Dremel EZ456B Cut-off Wheels are designed as a handy tool for a range of jobs, including cutting a slot in a stripped screw head for easy removal with a flat-head screwdriver. These cutting wheels are one and a half inches in diameter and work well with most Dremel models, and easily cut through small steel rods, though for any larger job it is recommended to find a different route. The feed rate must be controlled to prevent overheating and lessen the chances of slag, but cuts are overall clean in metals such as copper. While these work great for most jobs, it is important to note that they break and wear out quickly, so for a job that will require more cutting, it is recommended to purchase more discs. At about $2.50 per wheel these are a bit overpriced, especially if the metal center loses grip with the cutting wheel, rendering it useless. However, they are far more affordable if purchased in bulk from a generic brand from China.
