You can also do this with an angle grinder. However, the saw will give you a straighter cut. First, tie a straight edge to the paper. Your hand will fall off after the first sheet when you try to use the cutouts.
Cutting metal roofs with an angle grinder It is not recommended to cut metal roofs with an electric angle grinder or a cordless angle grinder. Metal roofs are so thin that much safer and faster tools can get the job done. Grinders leave sparks that can burn paint and also leave a dangerously sharp edge.
Method 1 Use a circular saw
- Wear thick gloves and a welding mask.
- Place the corrugated cardboard on the counter.
- Fold the blade of each blade for the metal.
- Hold the corrugated board with your non-dominant hand and start cutting.
- Slowly slide the saw through the metal.
The best tool / gauge 1 Electric scissors and / or nibblers. In my opinion, these are the best tools you can buy. Scissors work well, while nibblers are designed specifically for corrugated or curved plates.
Use 21 to 24 tpi blades for metal cutting. With the right blade, jigsaws can cut through wood with embedded nails, 1/8 inch. Structural steel, black pipes and sheets up to 10 meters thick (Photo 6). When cutting sheet metal, choose a thinner blade with 21-24 teeth per inch.
Make sure your saw or grinder has a metal cutting blade or wheel. When cutting galvanized pipes, it is important to use the correct type of wheel knife. A blade for cutting other materials, such as B. wood, does not work well for cutting galvanized pipes.
A nibbler or nibbler is a tool for cutting sheet metal with minimal deformation. One type works more or less like a knock and gate, with a blade moving linearly towards a stationary gate, removing small pieces of metal and leaving a tooth about 6mm wide.
Method 1 Cutting straight lines with a power saw
The Makita Knabber JN1601 has a large 1/4 turn for clean and precise work in trapezoidal sheet, cover sheet and other corrugated material. JN1601 has an ergonomic and slim housing design for easy grip, is extremely lightweight for easy handling and has an integrated feeler gauge for added comfort.
Fold the corrugated cardboard. corrugated coverage at the corners for better coverage. If it is a particularly large piece of metal, the safety precedents apply. Instead of a saw, use a lathe such as a CNC lathe that will do the job for you.
Draw a straight line on the sheet of paper with the field pen. Attach a carbide saw blade to a circular saw or general purpose cutting tool. Cut along the straight line you drew on the tile. Smooth the cut edge with a shiny cloth.
In the case of metal, the following applies: the thicker the material, the thinner the material. Therefore, a thickness of 29 is thinner than a thickness of 26. A minimum thickness of 29 is recommended for residential roofs, while a thickness of 26 is suitable for most applications. In areas with strong winds, precipitation or hail it is recommended to measure 24 meters.
Be sure to hold the Dremel with both hands for stability in the marked area. Then rotate the rotary tool at medium or high speed to get the force needed to cut or drill the metal. Dig into the metal with firm but light pressure.
