DH-412LCarbide Tipped
Long Hole SawT.C.T. LONG HOLESAW
Material
  • Tungsten Carbide
Using tools
  • Rotary electric drills (hand drills)
  • Drill presses
  • Magnetic drill presses
  • Various machine tools
Properties
  • Carbide hole saws are for stainless steel plates. The plates are cut sharply.
  • Simultaneously, the saws have excellent durability.
  • Possible for simple drill work until 4㎜ in depth about thin stainless steel plates and metal plates
  • It is faster than a HSS hole saw. The plates are cut sharply.
  • By outstanding durability, the materials are cut cleanly.
  • Loading of an ejector spring for the protection of a carbide tip and smooth emission of chips
Cautions
  • In installing the chuck of an electric drill, match the eccentricity well.
  • Do not swing the saw from side to side or do not twist it in drilling work.
  • Do not do consecutive work in a state of applying force compulsorily.
  • Unavailable for not flat surfaces but bumpy parts and pipes (steel pipes, stainless steel pipes, etc.)
  • Effective when cutting oil is used on the working part
  • Please be careful that the hole saw does not drastically touch a processing matter after the penetration of the pilot drill (damage to the carbide tip due to a shock)
  • In consecutive work, maintain low speed. It should be used fitting to the rotation speed according to workpieces.
  • It should be used in low speed as the size of hole saws becomes bigger.
Use and materials
  • Possible for drill work about tiles, gypsum boards, asbestos plates, artificial marble (~4㎜), etc.
  • Power distribution boards, operating panels, control panels, stainless steel plates, FRP, cast iron slabs, aluminum plates, zinc iron plates, etc.
