CPROSP Concrete Hole Saw Kit Wall Drill, SDS Plus &Max Shank Hole Saw, for Cement Brick Wall, Kit 30 40 65 80 100 mm

I absolutely love this product! It’s even better than I expected. Super reliable, great materials, and works perfectly. I would buy it again without hesitation.

Man this tool surpassed my expectations. A novice at diy, this things packs a punch, clean cut hole, both inside and outside. Worth every penny spent. Many more holes to cut, but has a lot more to go. Ps, you won’t be disappointed. A good drill is key.

They do the job but it is almost impossible to take them apart when finished. Be sure to use anti seizure.

I bought this product after seeing a review on it and it worked better than expected. It did exactly what I needed it to do and that was to drill through 5" of concrete with rebar in it. I will buy again.

This CPROSP Concrete Hole Saw Kit offers exceptional value for the price. The set includes a variety of sizes, covering most common needs. The hole saws themselves are durable and cut through concrete efficiently. I've used this kit on several projects and it has performed admirably. The only drawback I've found is the process of changing out the different bits. It requires two pipe wrenches to tighten and loosen the connecting rod, which can be a bit cumbersome. Despite this minor inconvenience, the kit's affordability and performance make it a solid choice for DIYers and professionals alike.

Little expensive, but drilled through concrete just fine after 10 holes still doing fine...but careful when change the predrill in the middle. Once that bolt is taken out is need retighten so often. So when you're drilling and it rattles, stop and retighten. other problem is how to change bit? It got jammed and tighter hard. No instructions for noob so anyone know better please update. Thanks.

Held up well, worked as they should thru concrete block. Did NOT dissapoint. Like everyone else said , YES , the set screw does loosen and come out. Keep tightening and check at least twice on each hole or you WILL lose it . At this price, they otherwise work just fine ! I would suggest, as i am doing, buy a few extra of the SDS Max Connecting Rods so each hole saw can be on it's own rod and be loc tite'd

These drill well. Put a bit of silicone on the screw head to make disassembly from the shaft easier

Merchandise received in good condition and on time. Quality as expected. Very satisfied.

Product was used to drill a large hole in a concrete fish pond to insert a drain valve .
