ABuff 4 inch 100 mm Hole Saw with Arbor, Heavy Duty 38mm Depth Bi-Metal HSS 4 Inch Hole Saw Blade with Positive Rake Teeth for Cutting Soft Metal, Drywall, Plastic, Wood, Fiberboard

If you have an arbor already that works with your tools you most likely wont need this one. I have a small hole saw set, but I chose to buy this saw with the arbor in case the ones I have did not fit. Turns out the arbor with this hole saw is too fat for any of my drills. Fortunately my existing arbors fit perfectly.

Very solid assembly. The Mandrel is solid - but do consider that you need 1/2 chuck, I luckily had several drills around but my first try was on a smaller 3/8 and it didnt fit but thats on me. The hole saw is solid. It does come with a wrench and spare center drills - very helpful. Dimensions wise the manufacturer is on the money - good 4 hole and with the teeth alignment as-is the final product is just a tad over 4 which is exactly as it is supposed to be for 4 conduits. Great product. Thank you

Nothing

I have used this type of hole saws for many years with varying success. This one did a GREAT job on the project that I was working on. I needed two holes cut, but a chest freezer is insulated and so 4 pieces of metal had to be cut and this saw went through the metal on the outside then through the insulation, and out the other metal side with ease. There was also copper tubing hidden in the insulation on both holes. This saw cut through all of this and the teeth remained sharp as new when the job was finished. ( Im making a fish smoker. The Reds are starting their run up the Kenai River here in Alaska)

Was on time Well packaged Did a good job

I used this hole saw to cut two holes in a 3/4 shiplap ceiling for fans. Worked quite well and the teeth on the saw look to be just as sharp as when I started. As others have mentioned it does required a 1/2 inch drill.

This hole saw cuts great and overall does a good job. Only reason I gave it a 4 instead of a 5 is because it had a little manufacturing defect and due to time constraints I chose not to send it back. The set screw hole was not properly threaded and the set screw would not hold. I was able to redrill and rethread the hole myself and use a slightly larger set screw. Other than that this hole saw is a good buy.

The product is good quality and comes with multiple bits, however if you want to use it to cut sheet metal holes for HVAC holes this is not a good hole saw to use. Basically the bit just keeps enlarging the pilot hole and the saw itself just mars the surface. Ended up using a jigsaw following the mar the hole saw made. I suspect the teeth are too large.

It was needed.

I really liked this product well worth money
