Will a bimetal hole saw cut steel?
A good bi-metal hole saw will easily cut through softer materials, such as plastic and wood-based items, as well as harder materials, such as steel and stainless steel. In addition to using high speed steel with cobalt, the heat treatment process used by the manufacturer will impact the life expectancy of the hole saw.
What can a bi-metal hole saw cut?
Bimetal hole saws are designed to cut everything from wood and plastics to ferrous and non-ferrous metals, including stainless steel. Although they are slower cutting than carbide hole saws they provide a much smoother finish.
Do you need a special hole saw for metal?
Hole Saw for Metal: Drill large holes in metal In metal, always use bimetal hole saws and keep the teeth sharper longer by using lubricating oil. But if you’re cutting a hole in your steel door for a deadbolt, or cut lots of holes, step up to a bimetal hole saw for metal. For those, you need a carbide-grit hole saw.
Does hole saw work on metal?
Hole saws are equally adept at drilling through metal as they are at boring through wood. Whenever possible, use cutting oil to lubricate the hole saw when drilling metal.
How thick of metal can a hole saw cut?
HSS and tungsten carbide hole saws are ideally suitable for metal cutting. You can use the shallow cut to cut steel up to 4.0 mm thick.

Can you cut wood with bi-metal blade?
The 2 kinds of reciprocating blades consist of wood and metal blades. Metal blades have smaller sized teeth and are used to cut pipes and metals. A bi-metal blade is used to destroy wood and metal. Wood blades have longer teeth and are used to cut wood.
What are spade bits?
Spade bits are for wood, plywood, and some plastics, and cut quickly with surprising precision. Use them only at high speeds, to prevent the bit from catching in the workpiece and the drill from trying to wrench itself from your grasp.
Can I use a diamond hole saw on wood?
A diamond holesaw is made out of a cylinder with diamond grit on the cutting end. It works by cutting material away similar to the way sandpaper works. It is not designed to cut wood, however I wanted to see if it was possible. But if you don’t get a clean cut, it doesn’t matter since no one will see the bottom.
What is a Forstner bit?
A: Forstner bits are mostly used in the woodworking industry to drill holes that are larger than those that can be made with ordinary drill bits. While other drill bits, such as spade bits, can perform a similar function, Forstner bits are significantly more precise and produce a clean cut with a flat bottom.
