شفرة الثقب الثنائية المعدن HSS-8%COBALT قياس 40ملم

For many craftsmen, choosing the right type of bimetal hole saw can be a challenging task. 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 40mm can be used for both metal cutting and 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 40mm 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 features more cutting edges, allowing for a cleaner 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 40mm HSS-8% cobalt hole saws, that is no longer a dream.
