This hole saw cut like butter, so clean and fast
Excellent bit, I couldn't be happier with it.
Works very good
I have every single bit from you guys ! I wouldn’t switch to any other brand . Makes my tile work easy and smoother
First of all the hole saw was really good quality and I haven’t had a chance to try it out but the 1 3/8” hole saw works really good so I’m assuming the 4 2/8” one is just as good thank you for quick shipping to Hawaii thank you. Will certainly be looking into getting more products from you guys.
This is one of the best hole saws I have ever used it cuts through porcelain like butter!
The hole saw saves a great deal of time cutting out roughin valves.
Great tool.
Working flawlessly!
Works great.
Will see how long it last.
I have used a lot of different hole saws over the years, I did like some of them however, they are not the same quality as "the Rook".
FAST!
Purposefully drilled through some standard dense porcelain to accommodate 3 light fixtures, it seems I was through the bottom of the tile before I could collect MY thoughts.
ACCURATE
I did the normal angled start, brought it up flat and used a slight ' wobbling' so I could eject the plug easier. Wiped the tile off and checked my crosshairs, perfect.
ECCONOMICAL
The quality of these hole saws appear to be far above the norm. I have since bought a couple of 1/4" bits for screw holes. I think they will last a long long while.
Works great. Clean and fast
Bolted this onto my wet polisher and it cut through a fabricated stone countertop like butter.
All the tools that I got from you were excellent they really work well and quick
Long lasting, cuts smooth, perfect for cutting holes for shower heads,etc
Amazing, the quality of these tools are unreal. Nice to know now that I can make the cuts and clean them up with this.
Love these bits! Work well for porcelain/ceramic tile and granite/quartz as well.
These hole saws are fantastic!!
Exact replacement to the, um, previous company. Lol. Thanks for the consistency!
Loved it great product, cuts very well
Great Holesaw! I used this to punch a few holes in a toilet flange circle cut and it went smoothly. I look forward to using it more often.
Extreme quality. Will last a long time.
These things are the bomb!!
I had all the tools from Crowne except this one and so glad I bought it. Makes life so much easier
Un servicio muy agradable y el producto muy recomendable excelente calidad
Quality and performance is what you can expect from Crowne Tools hole saw line up.
Cuts smooth with no chips. Long lasting. Cuts like butter through strong porcelain
And say hello to the ease of the grinder ! Much easier to use especially in conjunction with the hydro tail ! Leave that drill motor in the tool box for another project and make the switch to a 4.5”grinder , never going back ! Made a believer out of me in one shower
Excellent Hole Bit Clean and Fast Cutting.
Great quality and price
Best hole saws I’ve used in 12 years!
Recently purchased.Very pleased with it's performance on the 4 holes I've used it for.
Professional tile contractor 25yrs opinion.
