After trying this hole saw I must say that it is an excellent addition to my cutting tools collection .IT delivers precise and clean cuts, thanks to its four teeth clearance design. It is also sturdy and durable, making it perfect for industrial and scientific use. The only downside is that it tends to be a bit on the pricier side. But considering its top-notch performance, I believe it is a worthwhile investment. Overall, I highly recommend this hole saw for anyone in need of a reliable cutting tool..
