ChipLoad Machinist Calculator

ChipLoad is the machinist calculator built by a working machinist, for use standing at the machine — big targets, plain numbers, and not a subscription in sight. 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 shown, plus 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, right-triangle Trig • Material Weight — six shapes including square tube and angle, with going material rates and a total price for the piece • Job Cost — 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.
