I purchased a masonry cutting bit from this brand and was completely disappointed. According to my experience, the product was incredibly dull and barely made a dent on the surface I was trying to cut. I expected a much higher quality product from an industrial and scientific brand. The only pro I can think of is that the bit didn't break during use. However, the cons far outweighed that small positive as it was a complete waste of money. I would not recommend this brand's cutting tools toβ¦
Pros
Long-lasting and durable carbide tipped bit
Cons
May struggle with cutting through extra hard masonry materials
I thought the price of these carbide tipped SDS bits was the best since they have 16 bits. Now I believe the reason is that the quality and materials are below standard. 3/16 bend after ONE use. I'll come back and get a branded 5 piece set, probably around $40 but worth being able to drill precise holes.
