6 Inch Hole Saw with Arbor for Metal Wood and Plastic Cutting, 152mm Bi-Metal Hole Cutter for Different Project with Smooth and Flat Drilling Edge, Fast Chip Removal, Handy Hole Saw Kit Set

Bottom line; Exactly fits a 1.5" Umbrella pole - no loose wobble at the tabletop.Wife wanted an umbrella over our wooden picnic table that sits in direct sunlight in late afternoon / early evening when we would most likely use it with the kids for a Grilled Burger / Hot Dog dinner. Totally agreed with her idea.After purchasing the umbrella and the sand-filled patio base-stand for extra stability, I was faced with the challenge of cutting a perfect circle hole in the center our custom-made wooden picnic table.After reading several reviews on 1.5-inch hole saws being sold on Amazon, I tossed the dice and bought this one.It couldn't have been easier! Done 100% in less than 5 minutes. A perfect 1.5-inch hole with smooth sides that allowed the umbrella pole to slide thru the picnic tabletop and be tightened into the patio base-stand. Absolutely no wobble.This was a "one and done" purchase for under 10 bucks so I can't talk about its sharpness over the long-term.The one piece of advice I will offer is: Use a slower drill speed than you'd think and let the blade gnaw thru the wood.Lift the blade up occasionally to clear the debris and renew cutting. You are cutting thru - not burning thru to make the hole. Take your time and do it right the first time.

Does a great job on OSB! Perfect holes one after another. Works on a 18V cordless drill, but sometimes the drill struggles a bit. A corded drill might be better. The only negative is the bizarre pin arrangement. The pins are not attached to the arbor and fall out pretty easy. I ended up using the saw without them and it worked fine. Not enough to take away a star anyway. I would definitely buy this again.

If you are looking to build cornhole boards, this $10 investment is well worth it. It will give you perfect holes, and save you a tone of time. Jigsaw's stink compared to this handy thing.

This tool does the job. It’s a good idea to start the cutting process backwards for a cleaner initial cut, and then continue forwards. Be cautious, though. If your drill is set in drill mode, which provides high torque, this tool could mess up your wrist, especially when cutting through tongue and groove wood. The dust collecting bowl works quite well; it almost collected all the dust.

Worked good. However, I was only cutting treated wood deck. It came with an extra center drill and an Allen wrench to change the center drill.

Used it for my kitchen cabinets to fit the duct vent, cut through half inch plywood easily and served purpose. Well made

Purchased this bit to save me having to look around in my tool room for a 2 inch hole saw. Needed it to drill holes and a few pieces of PTFE and HDPE sheets. Worked well on the holes were very clean minimum cleanup required. Anything short of metal I don’t see how you can go wrong with this. Only way it could be better is if it came with a plastic case.

Purchases due to the inexpensive price did the job that I was looking for
