Hole saws cut openings in steel, non-ferrous metal, plastics, plasterboard and wood. RUKO multi-purpose hole saws are available in sizes up to 8-1/4 inches, with hardened steel backer and cutting edges made of either high-speed steel (HSS) or 8% cobalt high-speed steel (HSSE-Co8).
These multi-purpose, bi-metal hole saws have an alloy steel jacket and cutting edges of either
high-speed steel (HSS) or 8% cobalt high-speed steel (HSSE-Co8). RUKO hole saws are available in
various sizes ranging from 9/16 inch (14 mm) to 8 1/4 inch (210 mm).
Inch and metric equivalent (mm) hole saw sizes are stamped on each hole saw blade.
Cutting edges of HSS or HSSE-Co8
Alloyed steel 6135 jacket
Cutting depth up to 1 1/2" (38 mm)
High rotational precision
Hole saw and shank are in two parts, so hole saws of
different diameters can be exchanged and fitted faster
Positive chipping and cutting angles ensure more
Teeth welded onto steel jacket
HSS hole saws have 5 teeth per inch. HSSE-Co8 hole saws have
6 teeth per inch
Good chip removal
Slots in the jacket side allow easy removal of cutout
Exchangeable centering pilot drill bit
Hole saw kits include a selection of saws in plastic cases
Accessories include arbor holder assemblies and replacement pilot drill bits
Hole Saw Applications
Use high-speed steel saws (106xxx) with varied cutting teeth for more easily cut materials,
such as unalloyed steel (up to 700 N/mm2 strength), non-ferrous
and light metals, plastics, plasterboard and light building
boards, fiberboard, plywood and wood.
Use 8% cobalt high-speed steel saws (Co8 series 126xxx) with fine cutting teeth for cutting harder metals
such as alloyed and non-alloyed steels (up to 1,000 N/mm2
strength), high chromium alloyed steels, such as stainless steel,
steels resistant to rusts and acids, non-ferrous and light
