Evans Drill Bit Key

One tool you shouldn’t be without when changing your drum heads.

This thing is an amazing time saver if you’re a tuning perfectionist, like me. You can use it to quickly get all of your tension rods up to the same tension, and then fine tune with a TuneBot. It’s typically accurate enough to get every lug within 2-3 Hz of one another. The lowest tension settings may still be too high if you have really floppy floor tom heads, but it works great for “normal” tunings, including snare reso heads which are typically super tight. One thing to note is that the “clutch” does not fully disengage when you’ve reached the set tension. The plastic part will click out of position to let you know to stop, but you can’t just keep cranking it like you can with a torque wrench. It’s not a big deal, you just have to be careful to twist it at a reasonable speed so you don’t miss the click.

Fast and easy way to get every lug on the drum to the same torque. Depending on the trueness of the drum, hoop, and head I have had great luck with this also being nearly in-tune, making getting in-tune trivial compared to guessing at the tension by-hand before moving to the ear-checks for each lug. The numbers/measurements are a bit arbitrary though. You can't set "1.25 ft/lb of torque" for example, you just set it to "4" and whatever ft/lb that happens to be, that's what you get... but at least all lugs are at the same starting point for tuning! (Note: to get good results you still need to add tension to the head evenly, doing a star-pattern as you slowly bring up the tension. This tool just lets you bring each lug to a specific torque at the end. You can't skip the beginning though, the head material should be stretched evenly and slowly as you get it seated on the bearing edge before finally setting the tension on each lug with this tool.)

Concept is good. The small print is hard to see. Sometimes it’s hard to remove the key due to the strong magnet. It’s a good tool for tuning drums. It works well. I use it all the time.

Easy to figure out, works like a charm. Good for getting your heads to a relatively uniform tension, fine-tuning by ear still needed for best results.

Igual que con la llave cordón tambor es lo mas, muy pero muy buen producto

Works as advertised! Fastest wat to get a drum in tune with itself.

Comparing to the 2 other popular tuners at twice the money, this is a steal. Easy and fast to operate and right in tune.
