Dremel's line of Max Life high-performance accessories provide long-lasting performance and impressive durability. Built to give you longer lasting, stronger performing, versatile accessories. The Max Life 561HP Multipurpose Cutting Bit is coated in titanium nitride and engineered to last 2x longer than the standard, non-coated Dremel 561 Cutting Bit. For use with wood, plastics, laminates, aluminum or vinyl siding, ceiling tile, and fiberglass. Always cut in a clockwise direction. Start the bit into material at 45 degrees, then slowly bring it to a 90 degree angle for clean, controlled cuts. Pairs great with the cutting guide included in the Dremel 565 Multipurpose Cutting Kit for added precision and control. Compatible with all Dremel high-speed rotary tools. One bit included per package.
