Based on my observations, this drill was more trouble than it was worth. While it was advertised as a durable option for industrial and scientific use it failed to deliver where it counts. The cutting speed was sluggish at best, causing delays in my work.The only positive aspect was the alloy construction. Unfortunately, this did not make up for the drill's overall lack of efficiency..
this hole saw is a game-changer for those in the industrial and scientific fields. The alloy construction ensures durability and precision while the undetachable design makes for hassle-free usage.However the lack of size options may limit usage in certain projects. Overall, a must-have tool for any professionals arsenal..
Pros
Highly durable due to the alloy material used
Cons
Difficult to replace or repair if drill bit becomes dull or damaged
This is a true metric drill! However, a drill is required to get an accurate 22mm diameter hole. As with most things, don't expect a perfect hole unless you're using it with the right hardware.
