CHEMITOOL CUTTING HSS M42 Bimetal Hole Saws Ø20MM 8% Cobalt

CHEMITOOL bimetal hole saws are made of M42 high-speed steel (8% Cobalt), thus offering excellent cutting capacity in materials with a higher hardness, giving the professional excellent performance. These hole saws are distinguished by their excellent quality/value ratio.
CHEMITOOL hole saws are prepared for all types of drilling, this being the product indicated for quick drilling and excellent material removal.
The number of teeth per inch in constant/fine format (10 teeth per inch) allows holes to be drilled with a perfect finish, especially in metals such as stainless steel, steel, aluminium and non-ferrous metals. This saw is suitable for large hole drilling jobs in more confined places.

Bimetallic hole saws have been developed to withstand high pressures during the work process, thus helping to ensure a constant cut.
Adequate working speed/revolutions per minute is essential for increasing the lifetime of the hole saw, and it should always be used at a 90º angle to the contact surface.
