Hi mates, thanks for the add. I’m trumpet player and need your help, please.
Just for curiosity and not for my comercial purposes. So, there are any measures between the drills ? I know that it’s all about brands and his personal work but just checking out how they really work and how it’s this made.
Thank You All. link text

Btw, Jason Harrelson seems to have different measures standards:

Jason Harrelson seams to have different but in fact HE is right. If this foto is from him, he work on sequencial measures and drills. From 0,005” to 0,005” all over up and down on his drills, we can see it.

.135
.145

and not the Industrial Global Drills;

.128
.136
.140
.144

@Trumpetsplus precisely. That’s why I found the un-sequencial measures from one drill to another. It’s not a issue. Just want to know more and why. Cheers

@PortugaHorns : Now I see it - and yes, Harrelson's 5MM makes more sense!

Now you get it. Thanks for the support. Cheers.

@Trumpetsplus I play on my custom mouthpieces. You can see it on my personal table / chart. I love my 5mm. made a re-shape on cup and backbore to balance the drill. What a sound and easier airflow. Better lower range and highs, resonance at full capacity with awesome dynamics. I haven’t a clue that was #8 Drill. Now I’m better informed and still searching and trying new approaches.
