Ratings & Reviews for IRWIN Bi-metal Set 7 -Piece

Great product used only for a few doors

Not as good as the dewalt kit but it did its job. Pieces are plastic and not metal and if youre not careful while drilling, you’ll shave some plastic off from the double sided jig. Make sure you screw off the threaded adapter on the mandrell so it fits the big hole saw. Other than that, I drilled out 4 doors and they came out great. Just have some patience. Bolt plate template is crappy cause its plastic. But trace out the opening and chisel it.

Junk

Bought this to make hole on older door in my house. It is junk, does not stay in place and plastic gets cut by blade. Don't buy.

They didn't quite thing this thing through

First - the kit is very useful for putting the doorknob hole in a door. However, they either should have made the threaded hole in the two hole saws common, or they should have provided a second mandrel that fit the smaller hole saw. An alternative is just to use something like a (separate) 13/16 or 7/8 wood-boring bit. Note to, that while the template and router-like bit will help you define the inset for the plate attached to the bolt assembly of a doorknob kit, you will still need a router...

Junk

First time use and it broke. Dont waste your money.

Mandrel does not fit

The man rule does not even screw into the small hole saw. A smaller-diameter man rule is needed at the threads. Looks like $17 bucks was a waste.

Don’t use this if you are not a carpenter

Blaming the 15$ product and having none or almost no experience it’s just not correct. This plastic has not been made to hold bimetal blade but to show you where you should drill. Take jig, set depth 3/4 or 3/8 (check if your door knobs are adjustable), take pen and mark your circle and drill it.

Wonderful product. I had a deadbolt to install on a door that already had one on it, only it used a 1 1/2" hole and the new deadbolt was a 2" hole. I was able to secure this device to the door and use the hole saw to enlarge it to 2". Well worth the cost.

The product was simple, easy to use and did a magnificent job. Couldn't be more pleased.

Follow directions

I don't believe it's hard to use, but when your father in law decides to install your new door for you while you are at work, sometimes you end up with 2 doorknob holes because the first one was in the wrong spot. Just saying.

Great product

I didn't know they made this type of tool. Made job easier and faster.

If you have a hallow door....

Works as described. Good tool for the basic homeowner’s needs. Please note, if you are using this to cut a hole for a door knob in a hallow door, start on one side of the door. When you get to the other side, stop just before you cut through to the outter surface and back out. Then start from the other side of the door and repeat this process. This will help prevent splitting the thin outter layer of a hallow door.

Terrible

The plastic is too flimsy! It broke and the jig would not stay still!

The jig for doing the hole was fine. But the template for the striker plate was plastic. It wore off after the first use. The 2 1/8 saw auger was pressed in crooked so the saw blade couldn't go straight...it was wobbling. The tip of the drill bit for the striker plate broke off before I even finished the first door.

The hinge template was not useful for me mainly because I used larger hinges. The template for the latch was also not helpful. The guide for drilling the lock and latch were great and helped me make the perfect holes

Did exactly what it was supposed to.

I'm not sure why all the bad reviews. I purchased this as a one time use, not for production work, and for about half the price of the DeWalt kit. I only needed to install one deadbolt in a wooden door. The depth from frame was easy to set. The jig was held secure by two screws which left holes needed to mount the deadbolt hardware in anyway. The wobbly pilot bit was taken care of by readjusting the set screw and making sure it was on the drill bit flat. The hole saws cut as clean as any hole sa...

An Adequate Door-boring kit

I bought this Irwin kit because I had one previously and drilled about 30 doors and it was easy to use. I had to use it to bore a lock set hole on a mobile home door. The door had a hole that was smaller than 2 1/8 inch and needed redrilled larger. The door jig did the job but stressed the plastic so terribly as to make it unserviceable. So I bought another to use on any other doors in the future.

Works perfectly. Adjustable door knob depth. Even routes out for striker. comes with plate for routing hinges but haven't tried yet.

The jig & bit worked great on the holes. The router bit for the plates is not real easy to use.

Worked great!

Worked great, BUT over time it seem like the "bolt plate template" could wear out and loose its shape over time. VERY easy to use.
