Based on our own experience we found this industrial and scientific product to be poorly made and unsuitable for ANY serious cutting task. Despite claims of being bi-metal, the material dulled quickly and failed to cut through even thin metal sheets. The only pro was its affordable price, but that is outweighed by the frustration of having to replace it so quickly. Save yourself the hassle and look for a more reliable brand in the Cutting Tools section....
Pros
Durable bi-metal construction for long-lasting use
Cons
Potentially difficult to use on harder materials like metal or tile without proper lubrication
I recently purchased a bi-metal hole saw for my industrial and scientific projects .Through trial and error, I found that this product is the best in the market. With its sharp teeth and durable construction, it cuts through materials like butter. The saw`s teeth remain sharp even after REPEATED use. The only downside is the product's price which is on the higher side. However, it’s worth the investment as it outperforms other hole saws in the market. Overall, I would highly recommend this…
Pros
Efficient and durable in cutting through metal
Cons
Requires frequent lubrication during use to prevent overheating and damage to the blade
Most online advertisements for holesaws do not give clear information about the arbor. This requires a 1/2" fine thread shank, Home Depot doesn't stock fine threads of this diameter. I found a screw with a matching thread at ACE Hardware. I cut off the head of the screw so I can put it in my drill chuck. It is difficult to hold the drill in place while drilling as it didn't have a pilot drill and I couldn't use it in my application. I drilled a hole in 1 4" piece of clear plastic and attached…
