Six Categories, Growing Fast

  • 🔧 Shop — Material playbook, fastener calculator (SAE + metric), PEM & heat-set insert sizing, hole saw RPM helper, torque tables for inch and metric bolts.
  • ⚙️ Metal — Sheet metal gauge lookup, bend deduction calculator, SendCutSend specs. NEW: MIG/TIG/Stick welding calculators, filler metal cross-reference, plasma cutting, joint design, and weld symbols.
  • 🖨️ Print — FDM fit calculator for press/transition/sliding/clearance fits, hole compensation, elephant foot guidance, minimum thread sizes, and material reference.
  • 🎯 CNC — Router, Mill & Lathe. Feeds & speeds calculators, SFM tables, chipload reference, end mill guide, insert ID decoder, threading/tap drill charts, and operation parameters.
  • ⚡ Electrical — NEW: AWG wire gauge table, voltage drop calculator, Ohm's law calculator, resistor color code decoder, connector reference (18 types), battery reference, and EE formulas.
  • 🧪 Materials — Unit converter (length, temp, pressure, weight, torque, SFM → RPM), material properties comparison, tolerances by process, and surface finish reference.

How It Works

  1. Open it — Click "Open the tool" above. Everything loads instantly — the entire database is embedded in the page.
  2. Pick a category — Six groups across the top — Shop, Metal, Print, CNC, Electrical, Materials. Click a group, pick a sub-tab, and you're in.
  3. Look up & calculate — Type a material, select a screw size, enter a hole saw diameter — results update instantly. No submit buttons, no loading spinners.

The database can be updated by dropping a JSON file onto the database panel in the Tools tab. Your custom data is cached in local storage.

Built for the Shop Floor and the CAD Screen

  • Product design engineers and machinists pulling SFM tables, feeds & speeds, insert IDs, tap drill charts, and fastener specs.
  • Fabricators and welders dialing in MIG/TIG settings, looking up filler metals, and checking joint prep.
  • Electrical engineers and builders sizing wire, calculating voltage drop, decoding resistors, and picking connectors.
  • Anyone tired of Googling the same tables every time they need a tap drill size, wire gauge, or welding setting.
