High-Speed Steel Bi-Metal Hole Saw Drill Bit for Cutting Holes

Sammy MillerSammy Miller: I am winterizing a stay cat shelter that stays on my porch. Note, I bought the shelter on Amazon but it only has one entrance/exit and we live a semi-rural area with raccoons, opossums, and other critters who will kill a cat who can't escape. My solution was to buy this drill bit and drill the standard 6-inch hole recommended by kitty TNR and rescues. (Six inches will keep a lot of critters out while still being enough for a cat to enter/exit freely.) The bit is really sharp and it cut through the 4-inch thick cedar and insulation like almost nothing. This is my first time with a round bit and I learned not to press it. Just hold it in place and let it do the work. This bit will do the work in no time.

Note: The work isn't done yet. I have protected the edges of the hole with Gorilla tape on both sides and through (see picture). And before the snow comes, I will be lining it with heat-reflective material and adding a heavyweight vinyl slitted closure to keep the heat in as the kitties move in and out of their little home. Also, I'm adding a windshield to the fence around the porch.

This entire project is made up of Amazon purchases.

Scotty J: I bought the 5 3/4 inch hole saw to cut the hole in concrete board for the shower valve assembly and it did a perfect job of it, ate right through the 1/2 inch concrete board with no issues at all, teeth are still sharp and it probably took less than 5 seconds too.
Great value here.

Deshi Bhai: The product does cut through reasonably cleanly. Though arbor becomes very tight after cutting a few prices and it is stuck now. The design of arbour should be different . It is just on threads and gets over tightened after cutting a few times

Schuy1: Had to make a hole to fish my 8 surround speaker cables through my 9mm thick gyprock ceiling - worked a treat ! Recommend and good value.

てーちん: テレビ台のローボードの中に全録レコーダーを収納すべく24時間稼働で熱で壊れないかと思いファンと一緒に購入し、裏のベニヤにうまく120ミリの穴を開けることが出来ました。とても綺麗に開けられたので満足しています。ホームセンターでは、かなりお値段高いのと種類が無いのでAmazonで購入してとても良かった。ローボードの中はそこそこスペースあるのですがファン1個で全く熱がこもらなくなったので120ミリのファンを購入した方は綺麗に開けられるのでお勧めです。

sevanssevans: I needed 3 holes in 3/4" double-sided oak veneered plywood. I wanted to use my Dewalt quick-change mandrel.

I drilled 1 test hole then the 3 finish holes. The saw did an excellent job for me. There was no chipping or tear-out on the finished side; however, on the back side there was significant tear out. I didn't notice any difference in speed on the 4th hole. It cuts pretty quick for a hole saw in 3/4" plywood. The paint started pealing off on the 3rd hole but that's no big deal for me. I highly recommend using a small pilot hole before using the larger bit that comes with it. I didn't drill a small pilot hole and the larger bit skated a little off of where I wanted it to be.

The mandrel threads are not perfectly square with the surface of the saw. This isn't a big deal if you're using the included mandrel. For me the Dewalt mandrel threaded fine until the last 1/8" or so. I used channel locks to finish threading the saw. This is when I found the out-of-square mandrel threads as the saw doesn't sit flush on the back side of the saw. It's also when I discovered the holes for a quick-change mandrel are not spaced properly for my Dewalt mandrel. The 4 holes should be...

らき: 某大手ホームセンターでは、同じ内容のものが4倍の価格でした。ベニヤ板に使用しましたが、問題ない商品でした。インパクト用があれば良かったです。

Robinson: Ive tried them on plastic and honestly, for the price its not that bad. Have yet to try it on stiffer materials such as wood, but for now, it drills through plastic super well. Great product for small tasks.

Product Pros & Cons....

Pros:

- Drill bit works on a hand held drill

- It works (my photos show the result)

- It's pretty sharp. Not exacto knife razor sharp but obviously sharp to cut all my holes.

- I guess this is what they mean by "self-feeding" the drill bit drilled into the wood first, then the hole saw grabs onto the wood and then it begins cutting the hole. This made it VERY easy to cut a perfect circle.

- It has slots on the sides of the drill bit. Makes it easy to stick a flat head screwdriver into the slots to eject the wood that gets stuck in the drill bit (My photo shows the wood caught in the drill bit)

TIP:
Stick the flat head screwdriver into one of the slots. Push the wood out a...
