شفرة الثقب الثنائية المعدن من رونيكس 5232RH- بحجم 70 ملم

For many craftsmen, choosing the correct type of bi-metal hole saw is not an easy task to do. These cylindrical cups with serrated edges are used to cut holes of various sizes in various materials. That's why Ronix has manufactured 20 to 127mm bimetallic hole saw blades to meet all its customers needs. 
The Bi-Metal Hole Saw 70mm is suitable not only for metal cutting but also for wood processing. The bi-metal hole saws are available in the two tool steels HSS and HSSE-Co 8 (8% cobalt). The Ronix Bi Metal Hole Saw 70mm is HSS-8% cobalt with fine teeth, that ensures the tool does not get caught in the material and will run smoothly. This Bi Metal Hole Saw has a larger number of cutting edges, which allow a clean cut. 
Added cobalt to the tools will get them an extremely high hardness which enables them to cut in different type of steel. Many find stainless steel hard to cut, but with Bi-Metal Hole Saw 70mm HSS-8% cobalt hole saws, that is no longer a dream.
