Thousands of Fiberglass Strands
Quick-Snap Clip for Weights
Wrist Strap with Swivel
This depth gauge tool gives you a straight, accurate read on your drill hole depth. Drop the line, feel the weight hit bottom, and check your mark. Quick and simple.
The connector is built tough. It doesn’t snag on the collar or scrape on rough rock. It keeps the weight tight and holds up after a lot of use. The fiberglass line is easy to see and doesn’t kink much, so it stays workable on the bench.
Use it when you need a clean depth check before loading. Works for production holes, trim shots, or anywhere depth matters. No guessing. Just a true depth read every time.

Frequently Asked Questions
FAQ's - Depth Gauge
What is a depth gauge tool?
It’s a simple tool used to check the true depth of a drill hole before loading.
How do I use the depth gauge?
Lower the weight until it hits bottom, pull the line tight, and read the depth at the collar.
Why should I use a depth gauge tool instead of guessing?
Because guessing leads to uneven loading and bad shots. A depth check keeps everything consistent.
Does this depth gauge have a strong connector?
Yes. The connector is built to last and doesn’t snag on the collar or rough rock, especially when purchased as an assembly with our lead weights.
Is the fiberglass line durable?
Yes. It holds up well in dust, wet holes, and day-to-day blasting work.
Can I use this in production and trim holes?
Yes. It works in any drill hole where true depth matters.
Does the tool come with a weight?
Yes. It can. Make sure to select a weight option before adding to your cart and we will connect the weight to the tape before shipping it out. The weight drops without problems and makes it easy to feel the bottom of the hole.
Is this similar to a drillers tape?
Yes. Sometimes depth gauge and drillers tape are used interchangeably. Typically, however, driller's tape comes with an attached reel. We also supply a tape and reel here.
