Features
Aggressive cutting action and M3 HSS cutting teeth to give a very smooth finish.
Cuts up to 40% faster then constant pitch saws.
The varying tooth pitch gives substantial reductions in noise by disrupting harmonics.
Tooth life is greatly extended, as is battery life when used with a cordless drill.
Suitable for all uses: engineering, construction and maintenance.4 to 6 teeth per inch.

Material
Bi-metal M3 high-speed steel cutting edge

Bi-metal (BIM) is a high-carbon steel body for flexibility and break-resistance, and high-speed steel cutting edge for heat-resistance, hardness, and durability. On average they last up to 10 times longer than high carbon steel.
