BoschHE1 2-Piece Hole Enlarger Kit

This is the best tool you could ever have in your tool box . Works perfectly and is very easy to use and works perfectly. Had yo chance about 10 hole sizes so I ordered one of these because I didn’t want to mess up the super pricey cabinets I was installing. The holes need to be opened up 1/8 inch.

I was hired to replace the trim parts on a spa tub and the trim kit customer bought would not fit the existing faucet stems. So she ordered the rough in kit for the trim. Come to find out that the holes in the tub were 1 1/4" and the new rough in kit needed a 1 1/2" hole.I ordered the Bosch Enlarger Kit and along with a 1 1/4" hole saw and a 1 1/2" hole i was able to enlarge the holes with no problems.Some people are saying that the smaller hole saw is hard to get off after use but what I found was that when you break loose the larger hole saw with a wrench and channel lock pliers the smaller hole saw comes off with the larger hole saw.It works great and if you need to make some holes bigger this will do it.

This is a fantastic tool that solves a complicated problem: how to enlarge an already existing hole cleanly and safely.In situations where you can't or don't want to clamp a sacrificial piece of wood to allow the pilot bit to guide the larger size hole saw, you can simply use this adapter.Very simply, it allows you to combine the smaller, original hole saw (acting as a pilot bit) and the larger, new hole saw together. This setup makes the smaller hole saw act as a pilot bit for the larger hole saw.To connect:- Attach adapter to any hole saw- Attach hole saw to Quick Change mandrelTo release:- Pull back black sleeve to release hole sawThe smaller washer is for hole saws 9/16" to 1-3/16" in size, while the large washer is for hole saws 1 1/4" to 6" in size.

I just received this item so I have not used it yet. As usually happens with this type of tool, you buy it “after” you really needed it. I can tell just by setting it up that it is solidly made. The concept is simple so I’m sure it works as advertised. What I really like about it is that you can fit 2 saws with the same diameter arbor treads on it at the same time. This applies to both the larger and the smaller size. You can of course also use saws with different size arbors. It also has a nice release lock to snug in the saws after you screw them on. When I drill the wrong size hole again and need to use it, I’ll update my review.

This has been extremely useful. I have loaned it out so much that I ended up buy a second one.Extremely easy to use and takes care of that "oops, holes too small" issue.Wont help with the "oops, holes too big" issue.

If you have ever used a hole saw to drill a hole only to discover that it should have been bigger, then this is what you need. I have tried a simialr product made by starret, which at the time I purchased it was the only such product available. I thought that product was a lifesaver. Eventually, like most useful tools, it ended up magically walking away. The bosch product is very well made and offers one major improvement over my previous enlarger. The pilot hole saw sticks out farther. This may not seem like a big deal but when drilling through softer materials like drywall the teeth of the pilot holesaw are through the material. This keeps those teeth from chewing in sideways and makes it much easier to start the new bigger hole. Overall I am very happy with this product and hopefully it didn't come with those magical legs my last one had.

Enlarger worked fine for the holes I wanted to drill. However, when I was finished, I was unable to remove the hole bits from the enlarger base. For me it was a one time use. I tried multiple ways to remove the hole bits. Possibly there is a trick for removal, but I have not been able to find it. I rated it a three, as I currently am unable to re-use it for other size holes.

Had to replace lock sets on my new house and was surprised that the front door lock had only a 1 5/8 hole cut for the old hardware. I used 2 dewalt hole saws with this bit and got a nice clean cut and perfect fit for the new deadbolt.
