  • Good quality

Works great this is my second one bought one for work and now one for my home shop

  • Machinist must have!
Style: Calculator
If you’re going to work in any machining field, this thing has it all! Took hours out of my college classes (machine trades) just from not having to write out tons of equations and conversions. I lost one, and immediately bought another. Don’t let the price deter you, it’s WELL worth the money. It’s so much more than a calculator. ... show more

  • Awesome Calculator
Style: Calculator
I bought my son this camera for his job. He read the manuel on how to use it and it really does calculate the feed rates for his machine super fast. He can get the calculations faster than doing just the math. He loves it for work. He is a CNC machinist.

  • Great functionality, very useful in the shop.
Style: Calculator
I've been using this for a few weeks in my machine shop, and am quite impressed! While the pre-stored feeds/speeds/etc aren't easy to use compared to phone apps/slide rules, the rest of the calculator is great! I use it in particular for fraction/decimal math, as well as conversions. Quite solidly made, and the flip over cover is nice. I'm a touch concerned about the chemical resistance of the buttons, but I've so far been lucky enough to keep it away from my cleaning chemicals. I DO note however, it seems to use batteries pretty quickly. After only ~2 months of use in my home shop, I am already getting a 'low battery' warning. ... show more

  • Machinist Calculator
Style: Calculator
Originally bought this as a gift for a family member who was a machinist for many years. I thought he would appreciate this gift and use it frequently. Although it had all the features he might need, He was OLD SCHOOL and preferred to look things up. Additionally he had a similar calculator he was comfortable with. I'm sorry that I cant give a detailed review, but I am not the machinist with 30 years experience. ... show more

  • Excellent Machinist calculator
Style: Calculator
If you are a machinist or just a someone that likes access to machinist data, this calculator is perfect. I had purchased the Calc Pro 2 app for my iPhone and found it so useful that when this went on sale, I decided to purchase a dedicated, stand-alone calculator. This is an excellent calculator that I use for my lathe and milling operations. Feed and speed calculations for different materials, cutters, and operations as well as drill tables and tap/die tables. Makes looking up charts and tables obsolete. I highly recommend this calculator. ... show more

  • A great tool to have in your tool box.
Great Calculator. This is a must have for anyone who works in a machine shop. I love it. It takes a few minutes to get use to but the more you use it the easier it is. I really enjoy the ease that it makes things in the shop..
