Eight tools for the math and reference data every machinist needs. Shop rate, job quoting, profitability analysis, metal weight, speeds & feeds, tap drill sizes, hardness conversion, and surface finish. No signup. No email. Everything runs in your browser.
We build job tracking software for small machine shops. These are the tools we needed ourselves. No vendor bias, no paywall, no catch.
What should your shop actually charge per hour? Loads labor burden, depreciates your machine honestly, allocates overhead, and gives you a break-even plus a real target rate.
Paste your last 30 days of completed jobs. See which ones actually made money once loaded labor, machine rate, and overhead are applied. Losers highlighted, customers rolled up by weighted margin.
Price a new job from material, setup, cycle time, quantity, and margin. Shows price per part, total job price, and the quantity at which setup cost is paid back.
Pick a shape, pick a material, enter dimensions. Get weight in pounds and kilograms plus an approximate material cost range. Imperial and metric units.
Pick your material, tool coating, and operation. Get recommended SFM, RPM, chip load, feed rate, and MRR. Shows the formulas so you know why.
Complete tap drill chart for UNC, UNF, and Metric threads. See recommended drill sizes at 50%, 65%, and 75% thread engagement. Enter a custom drill to see the resulting thread percentage.
Mill cert says Brinell, drawing says Rockwell C. Type in one number, get every other hardness scale plus approximate tensile strength. Full ASTM E140 table for carbon and alloy steels.
Drawing says Ra in micrometers, your profilometer reads microinches. Type in one, see every other unit. Plus which machining processes can actually hit your target finish.
These tools are free forever. No email gate, no ads, no tracking beyond the basic page view counter. Everything runs in your browser and your numbers stay on your computer. We built them because we needed them ourselves.
