Great App. Really easy to use & the speeds & feeds are spot on. I use it all the time.

### 1/5 — Crashing

*2022-02-02, version 1.0.2*

App is crashing since last iPhone update. Can’t start it.

### 1/5 — App not working on ios 15 and up

*2022-01-21, version 1.0.2*

Used to be a great app until ios 15. App wont even open now. Please fix so i can give 5 stars!!!

### 1/5 — Horrible

*2021-07-16, version 1.0.2*

This is a terrible generalized calculator that is not at all specialized for Guhring drills.  It doesn’t even have a decent selection of material.  Only 4 or 5 generalized groupings.  Do not use this if you’re using high performance drills!

### 5/5 — Awesome app

*2018-02-26, version 1.0.2*

Love this app works well at work helps me a lot

### 4/5 — Great, streamlined calculator

*2015-08-30, version 1.0.2*

Easy to use and much simpler than using the Machinery handbook.   Unfortunately it is only in metric with no option for "English" units.

### 5/5 — Sales

*2014-05-23, version 1.0*

We'll done, very useful yet easy to use. Clean and sleek appearance.

### 5/5 — Improving your machining!

*2014-05-05, version 1.0*
