شفرة الثقب الثنائية المعدن HSS-8%COBALT قياس 79ملم

Choosing the right type of bi-metal hole saw might be a challenging task for many craftsmen. These cylindrical cups with serrated edges are for cutting various sizes of holes in a variety of materials. Therefore, Ronix has manufactured the Bi-Metal Hole Saws, from a range of 20 to 127mm, to cover all different types of demands.
The Bi-Metal Hole Saw 79mm 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 79mm 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 79mm HSS-8% cobalt hole saws, that is no longer a dream.
