The AMTECH bi-metal holesaw has a cutting thickness of 70mm (2-3/4 inches), allowing for the creation of larger openings for pipework, vent ducting, electrical fittings and more general construction applications. M42 high-speed steel (HSS) teeth are fused to an alloy body designed for liquid metal shock absorption so when the debris hits, the blade will be square and stronger, longer.
The bi-metal design of this reciprocating saw blade provides cutting efficiency and increased breakage resistance to use it on wood, sheet metal, plastics along with composite materials. The variable pitch teeth decrease vibration while in operation, which leads to a smoother and faster cut with even cleaner edges so that minimum finishing is needed. With a variety of hole sizes, it is compatible with most standard drills as well as cordless drills and arbors. It also has a deep cut ability for working with thicker materials and rugged construction to withstand tough everyday use.

FAQs
1. What is the cutting diameter of this holesaw
It acts like a 70 mm (2-3/4 inch) hole saw.
2. Will it be able to cut sheet metal?
As expected considering the HSS part of M42 HSS teeth, they are developed for cutting metallics such as sheet metal and other metals.
3. Will it work with cordless drills?
Yes, it will work with cordless drills.
4. Does it include an arbor?
No, it does not include an arbour.
5. Can I use this holesaw on thicker materials?
True, its slashed style allows it to be compatible with thicker stuff too layered.
6. What other types of materials can it cut (other than metals)?
It excels at cutting wood, plastics and composites.
7. Will it be useful for work?
Indeed, it is an industrial-grade holesaw for the toughest of applications.
8. How can I prevent cutting metal from producing too much heat?
Slower drill speeds and cutting oil are the way to go if you want good holes.
9. Are the edges clean?
Yes, the variable pitch teeth eliminate vibration providing fast clean cuts with less tearout.
10. How long will the holesaw last?
When used and cleaned properly, the bi-metal construction will allow it to stand up to years of hard use.
