Dremel 420 20P Multitool Cutting Disc

Good for slicing, making straight cuts and slots in all kinds of metal, like hardened steel, sheets metal or aluminum. Easily cut bolts, or make slots in rusted and/or stripped bolts / screws for removal with a screwdriver. Use with 402 Mandrel: unscrew the top screw on the mandrel using the wrench, put the screw through the middle hole of the disk and screw it back on the mandrel. If using the metal cutting wheels, cut on high speed – use light pressure. The wheels will last longer and cut faster if light pressure is used rather than heavy pressure and there is less risk of breaking it. Since these disks are abrasive, the diameter of the wheel is going to wear away. If the wheel becomes too small to execute the cut, stop the cut and replace the wheel. When using a cut-off wheel, we recommend using a two handed golf like grip to hold and guide the tool and go for a right angle. If you angle the wheel in the cut, the wheel will probably break.

Materials to use on:
- This cut-off disk can be used on different metal types, like aluminum, copper, cast iron. But also for short cuts in plastic or brick.
- On materials like a galvanized metal (Ductwork) or hardened steel, it’s best to use reinforced cut-off wheel (426)

Recommended speed:
- Aluminium 35000
- Brass 35000
- Copper 35000
- Plastic 10-15000
- Steel 35000
