Yes, this has been my preferred edge finding tool and through CNC mistakes, I break or smash about 1 per year. My last one broke as I pressed Z but the machine did not switch off of the X axis and the table went sideways instead of the spindle going up. The edge finder only broke because the threads on the inside of the hollow shaft are longer than necessary, causing a binding as the tip reached about 30 degrees. The threads broke. I realized that if the threads were shorter, the tip can go to 45 degrees without breaking anything. 1 minute modification... pull the tip out and slip a fork or pin through the spring to hold it out. unscrew the tip. grind the threads about halfway down. Screw the tip back in. Remove the fork. -Better than new!
I had never used one of these and was curious how the audible part worked. To satisfy other people's curiosity, the mechanism is very simple: it is a traditional edge finder with a flat on one side of the tip (visible in the product photo), and that flat stays out of the way for as long as the edge finder runs true. When it kicks out, the flat bumps against the edge making a "click click click click..." sound in time with the spindle speed.
My home shop is quiet, with no compressor running in the background and with a brushless DC motor in the milling machine, so the clicking is just fine. I'm sure it would not be very audible in a bustling job shop.
Pro: Well machined, tight tolerance tool that lasts. The two tone finish makes it easy to see when it jumps and the click is great feature in a quiet shop.
Con: Like everyone has said, if you work in a loud job shop environment, you won't hear the click.
I broke my Brown and Sharp edge finder after about five years of use (my own mistake, not a fault of the tool) and had to resort to one of my cheaper tools for the rest of the day. It only took a couple of minutes to decide I needed another Brown and Sharp. The shop I work in is relatively quiet and I love the audible feature of this edge finder, but if you work in a loud shop, save yourself a few bucks and buy the regular version.
These have been around for a long time. No batteries, no buzzers, no flashing lights. no high price. They just work, and they work quite well.
As others have said, the audible part is not very audible in a noisy area, although I can hear it in my shop with the compressor running and the music playing (rockabilly). But just watching for the tip to jump is the best way to use it, and that's what I do.
It works well and I use it when the shop is not too noisy.
As you can imagine, it isn't loud but it does work.

Description
The Brown & Sharpe 599-792-20 Audible Edge Finder is made from Hardness Rockwell C (HRC) 58-rated steel for increased durability, and is ground for smoothness and case-hardened on the ends for usability. It features a 3/8” shank and 0.200” head diameter, and is available in multiple sizes. Heads are manufactured to within .0001” of stated size. Audible and visual measurement capabilities help increase accuracy.
Audible edge finders release an audible click when the tip jumps, allowing users to hear as well as see the tool, for increased accuracy. The rotating instrument has a machine spindle that must be turning for the tool to work.
Brown & Sharpe was founded in 1833, had a major part in setting industrial standards in the United States, and has given its name to several standards, including a tool spindle taper, a worm threadform, and others. Brown & Sharpe was acquired by Hexagon Metrology in 2001, and has since focused on precision measuring equipment and metrology hand tools. The Brown & Sharpe line of coordinate measuring machines (CMMs), optical measuring systems, benchtop measuring machines, and precision hand tools offer consistent, high-quality design, construction, and performance. Brown & Sharpe has manufacturing facilities in North America, Switzerland, and China.
this product is everything it is supposed to be thank you. the audible feature is quieter than i thought but didnt buy it for that anyway,
In a home shop, the click when the finder locates the edge can easily be heard. Much better than a visual finder because you can watch the indicator and get a more precise reading. Appears well made and would recommend it.
This was a good deal when I bought it at $9, now they seem to want $30 for it, however, which is a straight ripoff.
Bought for Son's engineering class at UNCC. Very nice quality. He says it works fine.
Well made and works good.
