1-7/16" (37mm) Tungsten Carbide Tipped Hole Saw with 2Pcs Titanium-Plated Pilot Drill Bits for Hard Metal,Stainless Steel,Iron,Aluminum Alloy,Wood and Plastic

Very fair price for a high quality hole saw. Worked perfectly.

These pilot bits are a great deal and totally legit. At an electrical supply house, you’d pay around $20 for just one, so this was a no-brainer. They’re a bit long for the 1/2” and 3/4” carbide hole cutters, but they fit the 1” perfectly but they still work fine for the smaller sizes. Definitely worth it.

I used these to cut a couple dozen holes in stainless steel 16 gauge and this hole saw performed phenomenally. The holes were accurate and smooth finish with no jagged edges. Price is extremely cheap but the quality is definitely not!

I used this tool in order to cut a 25mm pocket in an aluminum casting. It worked very well in my drill press to cut the hole. Unfortunately the metric size i need is 25mm to put an oil sight glass in a motorcycle engine cover. The measured size using my calipers was 24.6mm. That was too small to be useable. If this tool was actually 1”, that should result in a metric size of 25.4mm. So I am unclear what size this is actually supposed to be. I do have a hole saw I bought, in a different amazon purchase, that was sold as a 25.5mm size. It actually measures 25.4mm. Which suggests that different size is actually 1”, right? The tool itself work great, cuts well. It ejects the cut plug and is easy to use. I would buy one again if I had confidence I could get it in the size i actually need. I’m a bit frustrated about what size I need to search for. 1” and 25mm are not the same actual size. This makes it hard to shop on Amazon. Unfortunately I had to ruin a motorcycle engine cover to collect this info.

I don't know what to say here. It worked great for the first 6 holes i drilled but, on the hole number seven 6 teeth broke off.

Drilling/ coring on 1 1/2 in butcher block island counter top to install pop up electrical plug. 1/2 inch into cut drill bit broke near top. They provide 2 so I was able to finish but coring was really slow. Also because of depth of core spring on drill bit compresses and doesn't allow a full depth cut. If you are cutting out cores to use for something the spring leaves a mark. Sending it back.

I'm using the hole saw to make wheels out of oak for a child riding toy. The finished wheels turned out great. However, they were hard to get out of the hole saw with the one hole on the side of the saw. Also the spring doesn't stay in, then when I was done it was compressed and also went into the wood. While cutting the wheels the saw dust was quite fine and took quite a while to cut. Picture sort of shows the burn mark of spring.

These are excellent. I have a project I've put off for 3-years because I destroyed too many M42 and M35 cobalt drill bits trying to fix beveled and plasma-cutter hardened holes in 1/2" steel. This drill bit took care of each 7/8-inch hole I need to fix in minutes.
