8 Inch Hole Saw with Arbor for Metal Wood Plastic, 8 in Bi-Metal Hole Cutter for Different Project with Smooth and Flat Drilling Edge, Fast Chip Removal，Lighter and Portable

I needed this for a kitchen exhaust vent. It requires a powerful drill and sturdy hand. It's big but cuts well. I found that a slower speed works best and makes it manageable. Just know that it's not quite big enough for 10" metal duct pipe but got me close enough.

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.

I recently purchased an all-purpose drill bit, and I have to say, it exceeded my expectations in every way. After reading some mixed reviews, I was a bit skeptical, but I decided to give it a shot for my latest home improvement project, which involved cutting through drywall, plastic, and wood. I'm thrilled to report that this drill bit performed flawlessly!First, let’s talk about its versatility. This bit glided effortlessly through drywall, making clean cuts without any tearing or fraying. For anyone who’s ever struggled with messy drywall cuts, you know how crucial this is. The precision was impressive, leaving behind a smooth edge that required minimal finishing.Next, I tackled some plastic. I was worried that the bit might melt or chip the material, as I’ve experienced with other bits in the past. However, it cut through the plastic like butter, maintaining its sharpness and not causing any deformation. This is a major win for anyone who needs to work with various materials.Finally, I put it to the test on wood. The drill bit made quick work of several types, from soft pine to denser hardwoods. It showed no signs of dulling, and I was able to achieve clean holes without excessive effort. The performance was consistent, making it clear that this bit is built to last.To counter the naysayers, I’d argue that the key to this drill bit’s success lies in its design and quality. While some users may have had issues, I believe that proper usage, including the right speed and pressure, plays a significant role in achieving optimal results. I’ve used inferior bits that required constant pressure and left me frustrated, but this one made the process enjoyable.In conclusion, if you’re looking for a reliable drill bit that can handle a variety of materials with ease, I wholeheartedly recommend this all-purpose option. It’s a tool that delivers on its promises, and I can confidently say it has become a staple in my DIY toolkit. Don’t let the skeptics deter you—give it a try, and you might just find it as indispensable as I have!

The media could not be loaded. Nice hole saw for the price. The hole saw threads directly onto the bit, which is different than conventional hole saw kits. It makes setup and use of this bit very easy, but also means you likely can’t exchange components from this kits to other hole saw kits.

Good tool, well made. I'm using it to install 7 inch vent pipe from kitchen exhaust through the roof. Still have the roof cut to make, but so far, the tool has performed like its more expensive counterparts in the box stores.

This product worked just as needed and cut the 6” hole I was wanting. I was cutting hard plastic and did well with the hole opening being just a tad over 6” but that’s due to the coarse teeth.Worked perfectly for my needs.

this Hole saw worked flawlessly and it came with the essential dual pin Arbor -- the alternate arbor without pins, threads only, should never be Used as they Create Hand and finger shredders of the rotating hole saw . The thread only arbors are meant for small diameter Hole saws only.
