This hardened hole saw is a game changer in the world of cutting tools. Industrial and scientific usage has never been easier with the sharp precision of this product. After I put it to the test, I was thoroughly impressed with the speed and efficiency it provided compared to other similar products. The only downside is that it's a bit pricier than some other hole saws on the market, but the quality and performance make it worth the investment.
Pros
Highly durable due to hardened construction, able to withstand repeated use.
Cons
May require a higher level of skill and experience to use effectively due to the larger size and potential for the bit to bind or wander during use.
Worked great. My mandrel from another smaller hole saw was not quite right, was too short making it difficult to start the hole but it worked. For those buying, you might want to think about the right mandrel.
Drill holes and 3" PVC pipe fit properly. This one has "twisted" or "snuck around" a few times, or whatever you call it, stepping aside and getting stuck while drilling. Another smaller size I used from another brand was not available so the design of the teeth may need some work. I'd probably get an arbor/arbor with a longer drill bit if I plan to use it regularly. The standard universals usually fit 2 holes. Great saw for the price!
