Multi-Purpose Hole Saws

• High Speed Steel (HSS) hole saws
  
  
• High Speed Steel Cobalt 8 (Co 8) hole saws
  
  

• Use High Speed Steel saws (HSS series 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 High Speed Steel Cobalt 8 saws (HHS Co 8 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 metals.
  
  

• Cutting edges of HSS or HSS Co 8
• Alloyed steel 6135 jacket
• Cutting depth up to 1 1/2” (38 mm)
• High rotational precision
• Sturdy construction
• 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 aggressive cutting
• Teeth welded onto steel jacket
• HSS hole saws have 5 teeth per inch, Co 8 hole saws have 6 teeth per inch
• Good chip removal
• Slots in the jacket side allow easy removal of cutout debris
• Exchangeable centering pilot drill bit
• Right-hand cutting

• Arbor holder assemblies with pilot drill bit for HSS and HSS Co8 Hole Saws
• HSS and HSS Co5 replacement pilot drill bits for hole saw arbor assemblies

• These hole saws are unsuitable for hammer drill operation
• These hole saws are unsuitable for use on stone, concrete or tile
• Only slight pressure required to start drilling
• Drill with light, steady pressure
• Avoid pendulum movements while drilling holes
• Follow table of recommended cutting speeds
• Use cooling agents recommended for specified materials
• For mounting pushbuttons, for a smoother cut and a better fit, use a RUKO knockout punch

HSS hole saws are priced from $4.75 to $44.50 .

HSS Co 8 hole saws are priced from $5.75 to $56.00 .
