## Description

Product Description HSS Bi-Metal Hole Saw Most users prefer a bi-metal hole saw for the majority of their work because it is compatible with a wide variety of materials. It also cuts faster and smoother and with reduced vibration due to the variable pitched teeth. HSS bi-metal hole drilling cutter for smoothly cutting in wood cornhole boards plastic drywall & thin metal The serrated saw teeth of a hole saw are typically set at a 60° angle. This is so that the teeth can “bite” into the material you are cutting. This spring uses stored mechanical energy to eject the slug from the cylindrical saw blade after your hole has been cut. The slots in the cylinder walls of the cutting blade allow chips and dust to escape more easily. Holes clogged with dust are the chief reason for stuck saw blades.

Review: Good bit of kit - Used this drill bit to create a hole in a plastic tray for a kids water play set. Worked great and caused no damage to the plastic despite my initial fears. Would recommend
Review: Good quality 180mm hole saw - Great quality large hole saw. Used to cut a hole through a cabin roof to fit a flue for a log burner. The hole saw is fairly heavy and sharp, cut through many layers very easily, although be very careful using a hole saw of this size in a drill. If it catches, it will lock up. I used a lower drill speed which helped. Pleased with this product.
