## Most critical reviews (7 lowest-rated)

### 3/5 — Excellent

*2021-10-25, version 1.45*

Has a good tap drill calculator for cut and roll taps with % of thread. Free!! Please add support for STI taps!

### 3/5 — missing materials

*2015-01-30*

this should have a material selector and into osf mill data. The way it is now you would open a paper book with that information and use this side-by-side. That defeats the purpose of having an app.

### 4/5 — Nice calculator
