Calculators & Charts for Tool Owners
The jobs that come after the purchase. What torque your wheel nuts take, which drill bit an 8g screw or a Dynabolt needs, whether a Ryobi battery fits an Ozito, how long a power station runs the camping fridge, what the mitre saw should read for a cornice corner. Metric, Australian brands, works on a phone in the shed.

Why these exist
Built for the questions owners actually ask
Most tool sites stop at the checkout. The questions that follow are the ones people ask on Whirlpool, OzBargain and the Bunnings Workshop every week: what size hole for this plug, what do I torque the wheel nuts to, does this battery fit that tool, what pressure is safe on the render, which way up does cornice go in the saw. The answers exist, scattered across PDFs, forum threads and imperial charts written for somewhere else.
Everything here uses Australian gauges, brands and units, cites the manufacturer data behind it, and links to the picks we already rank when you need the hardware. They are free, they never ask for an email, and they are built to be used one-handed on a phone.
Something missing? A blade and disc chooser by material, a laser level accuracy and fall calculator, a sanding grit chart and a deck screw calculator are next on the bench.
