Question about SAIT Portable Saw Cut-Off Wheel TM 12 x 1/8 x 1 BRUTE
A contractor was using a abrasive wheel A24R-BF to cut PVC Pipe. The wheel is designated for steel cutting. Is this an appropriate product for cutting PVC. I recently was involved in an incident where a worker lost an eye when a wheel ,of a competitor, designed for "Steel", broke and knocked the safety glasses into the workers eye.
I worked at a tool rental business while going to college and became familiar with OSHA requirements as it pertains to construction. There is an old saying that if you follow the rule-book by the letter things will quickly come to a grinding halt. I checked on OSHA web site and could not find anything on you question. I recall that using the correct blade only results in a cleaner cut, however there is the possibility that the pvc material can load-up on the blade and cause jambing. An inspection of the blade will answer this. More important is that all safety items are in place like the blade guard and that all workers in the vicinity of the saw are wearing eye protection. We used Norton brand abrasive blades and the following is their guide.
Concrete: For concrete/masonry - silicon carbide specification for brick, block, concrete, and other masonry materials.
Metal: For metal/steel - aluminum oxide specification for mild steel, stainless, and metal decking.
Asphalt: For use when cutting mostly asphalt.
Asphalt / Green Concrete: For asphalt and green concrete - silicon carbide in coarse grit range. For high performance, hot pressed wheels provide significantly longer life.
Ductile: For ductile iron and cast iron pipe - formulated with a special blend of silicon carbide (for cutting) and aluminum oxide (for long life). This specification is also suitable for cutting PVC.
Hope this helps, enjoy
