## Description

desertcart.com: Professional Stop Collar Set - Drill Bit Depth Stop - 8 Piece Kit (1/2”, 7/16”, 3/8”, 5/16”, 1/4", 7/32”, 3/16”, 1/8”) Superior Aluminum Split Ring Design : Tools & Home Improvement

Review: Excellent Quality. Aluminum has advantages. - With all the negative reviews, I hesitated a bit to purchase this set. However, what I received was essentially perfect in every detail. All the collars fit the corresponding drill bits closely, the hex wrench fit the screw heads, and the collars tightened up easily. The size markings are a handy feature. These things were basically a pleasure to use. I compared this set to a high quality (Taiwan) steel set that I also purchased. That set was not marked but otherwise worked well. But while doing the comparison, I found an advantage that aluminum has over steel in this application. With the steel collars, the torque needed to tighten the collar was greater than with the aluminum collars. This matters with the smaller drill bits because when you crank the screw down while holding the bit, the drill bit tends to bend. I did not have any trouble with the aluminum marking wood because I always used these while drilling through a jig of some sort.
Review: They’re aluminum. - They’re anodized aluminum. I thought maybe they might be plated steel. Aluminum invariably leaves behind marks that must be sanded off. A professional carpenter would NEVER use aluminum, but as I am no such thing, I do not care. I am extremely pleased with price, quality, and performance. Also, they’re conveniently marked with sizes in large, easy to read laser script.

### ⭐⭐⭐⭐⭐ Excellent Quality. Aluminum has advantages.

### ⭐⭐⭐⭐ Much improved over the standard set-screw stop collars
*by H***N on November 14, 2025*

I've always had a certain dislike for the standard set-screw stop collars. More than half the time they sit crooked after tightening. These stop collars are much easier to set and sit true on the drill bits. A definite welcome improvement. They do have some room for improvement though: 1. The size markings are on the flat surface and if you install that side down (which you eventually do at some point) the markings will be scratched off. I had to write the sizes on the side with a Sharpie. 2. The provided 2.5mm Allen wrench is too flimsy and flex too much when trying to tighten the screws. I use a 2.5mm from my set of Eklind Allen wrenches. 3. The screws are a bit too tight when tightening on the drill bit and difficult to hold in place. This might be because the collars are made of aluminum, but something I can live with.
