Using the Klein Tools 31860 carbide hole cutter is easy. First, make sure you've selected the right material to drill into, like stainless steel, mild steel, iron, copper, or brass sheets up to 3/16 - inch thick. Then, insert the cutter into your drill. The split - point pilot drill bit will help keep the bit steady and prevent it from moving around. When you start drilling, the integrated flange will stop you from going too deep into the sheet metal. As for conduit and pipe sizes, it works well with 1 - inch ones. Just be careful while using it and wear proper safety gear. For maintenance, keep the cutter clean after each use. You can use a soft brush to remove any debris. And if the pilot drill bit gets worn out, you can replace it with the 31874 bit.
