Light weight, but rugged design. It’s small size makes it easy to tap holding your work piece in your hands.

Paid 25 dollars. The 5/16 and 1/4 are both too small. It’s too tall for smaller taps and would be better if it were stepped. Guess I’m ordering the Big Gator now.

Light weight hard plastic, not metal. As a former machinist, I used to use all metal tapping disks like this. But the lighter weight makes it easier to handle in situations where you are free-hand tapping. Have used it several times with good results. Not for drilling, use a metal guide for that. A drill bit will chew it up.

This is a very affordable tapping block to ensure things stay vertical. The multiple hole sizes is helpful.

Works okay, but for the money it should be made of metal, not plastic.

The shaft of a #4 tap is considerably larger than the part that does the threading and the tap guide is 1" thick, which is deeper than the threading portion is long. Unfortunately, the tap guide has a hole sized for the #4 threading portion, but too small for the tap's shaft to enter. You can't actually use it to lie up a #4 tap.Carefully align a 9/64" drill to to the #4 hole in the tap guide and drill half way into the tap guide. You will then be able to insert a #4 tap far enough into the guide to start tapping the hole. Once the tap is started straight (a couple of turns) remove it, remove the tap guide, and then carefully start the tap back into the threads that you started and complete the tapping operation.Aside from this fixable, though totally unnecessary, design issue, the tap guide handles just about any size tap that you're likely to use. It's compact, light and inexpensive

Product is as described, made from Deleon and a good thickness. Unfortunately I cannot get a tap through the holes. The holes are smaller than the tap. Use caution in buying this. Be prepared to ream the holes to fit the taps.
