Let's talk about the Drillpro 5Pcs HSS 6542 Titanium Coated Hole Saw Tooth HSS Hole Saw Cutter Drill Bit Set a tool that claims to make easy work of metal and steel plate cutting.
With sizes ranging from 16 to 30mm, this set seems to have everything you need to tackle any project that comes your way.

I have to say this Drillpro set is quite impressive. The HSS 6542 material gives it a hardness that makes it more durable than other hole saws out there. The titanium coating adds an extra layer of protection against rust, which is always a plus. The split tip drill feature is a game-changer, as it guides the cutter gradually to the material and prevents any walking. The high-speed steel teeth make cutting clean, round holes a breeze. Whether you're working on metal or PVC this set seems to be up for the challenge.

Simply put the Drillpro set has a lot of advantages. It's versatile, durable, and rust-proof. The split tip drill and high-speed steel teeth are great features that make cutting easier and more efficient. However, it seems that the set may not be as effective on harder metals and some users have reported that the bits can become dull after extended use. Additionally, there are some concerns about the actual material used, with some questioning if it's truly high-speed steel.

Overall I would definitely recommend the Drillpro 5Pcs HSS 6542 Titanium Coated Hole Saw Tooth HSS Hole Saw Cutter Drill Bit Set. It's a versatile tool that can handle a variety of materials, making it a great addition to any toolbox. While there may be some concerns about the durability of the bits on harder metals, it's hard to argue with the effectiveness of the split tip drill and high-speed steel teeth.
