Hole saw TCT for metal in size 50 mm. Blades made of sintered carbide, which are characterized by significantly greater hardness and resistance to high temperatures compared to HSS high-speed steel. Intended for making larger diameter holes in steel, cast iron, non-ferrous metals, wood, plastics, etc. To increase cutting precision a pilot drill made of HSS steel is used. A spring mounted on the pilot drill allows easy removal of chips.

Product characteristics:

• high quality manufacturing, resulting in high work precision
• blades made of sintered carbide, up to 10 times longer life compared to standard bi-metal hole saws
• carbide teeth can be resharpened
• pilot drill made of HSS steel coated with a layer of titanium
• spring on the pilot drill intended for chip removal
• hole saw has a collar protecting against over-drilling
• solid construction reduces vibrations, which significantly increases drilling precision
• replaceable pilot drill and spring
• to extend the life of the hole saw it is recommended to use cooling lubricant
• safe handle chamfered on 3 sides prevents the hole saw from slipping in the drill chuck

Technical specification:
