Technical data: Shank diameter: 3.2 mm Cutting depth: 24.0 mm Max. working depth: 10.0 mm Width: 24.0 mm Length: 24.0 mm Height: 1.0 mm Maximum rotation speed: 35,000/min. This blade is suitable for cutting off, making straight cuts, and slotting in a variety of metals, such as hardened steel, sheet metal, and aluminum. Easily cut screws and bolts, or slot rusty or stripped screws and bolts for removal with a screwdriver. Use this blade with the 402 arbor: loosen the top screw on the arbor with a wrench, insert the screw into the center hole of the blade, and tighten it onto the arbor. When using metal cutting blades, remember to cut at high speeds and with light pressure. The blades will last longer and cut faster if you apply light pressure to the tool while cutting. This also reduces the risk of the blade breaking. As blades wear over time, the blade diameter will decrease. If the blade becomes too small to make the cut, stop using it and replace it with a new one. When using a cutting disc, we recommend holding the tool with both hands (golf grip) and setting the blade at the right angle. Tilting the blade while cutting can cause it to break. This cutting disc can be used on various types of metal, such as aluminum, copper, and cast iron, as well as for short cuts in plastic or brick. For materials such as galvanized metal (ventilation ducts) or hardened steel, it is best to use a reinforced cutting disc (426). Recommended rotational speed: Aluminum: 35000 rpm. Brass: 35000 rpm. Copper: 35000 rpm. Plastics: 10-15000 rpm. Steel: 35000 rpm. Package contents: 36 pcs. ** Illustrative photo.
