The online workshop is a set of tools for everyday work at the drawing board and on the shop floor: calculators and tables. Everything is calculated by your browser — the dimensions you type never reach any server. More tools will follow.
ISO 286 fits and tolerances calculator — enter a diameter and a fit such as ø30 H7/g6 and get the deviations, the limit sizes and the clearance or interference. Includes a guide to choosing a fit and to rolling bearing seats.
ISO 2768 general tolerances calculator — enter a size and the class from the title block, e.g. ISO 2768-mK, and get the permissible deviations for linear dimensions, external radii and chamfers and angles, and for classes H, K, L also the geometrical tolerances.
Steel grade equivalents — enter a grade from the drawing, e.g. S355J2+N, 42CrMo4 or 1.4301, and get the steel number, the product standard, comparable grades in DIN, AISI/SAE, JIS and BS, and a breakdown of the name.
