Bi-metal hole saw, the material is heat treated M42 bi-metal saw Strip and by an advanced electron beam welded together, then by a vacuum quenching, sharp, durable, easy to fall off of the cutting edge of tooth.

Suitable for cutting materials: aluminum, steel, steel castings, stainless steel, wood, plastics, etc.

Note: the hole when using fair use please control tachometer to prevent blade cracking, and keep adding coolant, in order to facilitate heat dissipation, extend product life.

Bi-metal hole saw new tooth to reconcile tooth pitch precision cutting of open air and variable tooth pitch opened

Hole saw fast cutting, easy advantage of chip
1, dual function, applied materials wider
2, chip-free, faster cutting speed
3, compared with common variable tooth Hole saws, extend the life 30%
4, compared with ordinary tooth Hole saws, not easy to saw or broaching
5, cutting depths up to 41mm
6, cutting diameter ranges from 14mm to 210mm
Super ability of sawdust and earthquake-proof so that it can efficiently and economically to the wood, a metal plate

Hole cutting Fastcut series applies to all on industry and construction, the maximum cutting depth is 41MM
