17 tools in one app

• Mill Speeds & Feeds — RPM, feed, chip load, MRR, HP and torque, with operation, coating, coolant, rigidity and interrupted-cut factors, a cut-intensity slider tuned to your machine, and depth/width suggestions per cutter
• Lathe Speeds & Feeds — G96/G97, insert shapes with depth-of-cut guidance, stock-diameter RPM bracket
• Drill & Tap, Drill Point & Countersink, Ball Nose finish stepover
• Thread Lookup (UN, metric, Acme), 3-Wire Measurement, Fasteners with torque and clamp load
• Drill & Tap Charts — cut tap, form tap, close fit and free fit
• Bolt Circle, True Position, Sine Bar, and right-triangle Trig
• Material Weight — six shapes including square tube and angle, with material rates and a total price for the piece
• Job Cost — quoted the way shops actually quote: marked-up material, setup spread over the run, scrap, and profit as a true margin
• A full calculator with history tape and scientific functions

Your machines are saved as profiles, your setups are saved on the phone, and every number is a starting point from the same handbook math you'd look up — verify before you cut.

Free vs Pro

A new install gets every tool for a 5-minute trial. After that, the free version keeps the Calculator and the basics of Mill and Lathe. ChipLoad Pro is a single one-time purchase that unlocks everything forever — no subscription, no ads, no account, and it works fully offline.
