Owner's Toolkit

Free calculators and lookups in Australian units, for the jobs after the purchase: which drill bit for an 8g screw or a Dynabolt, whether a Ryobi battery fits an Ozito, how long a power station runs the camping fridge. No sign-up, 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, does this battery fit that tool, will this power station get the fridge through a long weekend. The answers exist, scattered across PDFs, forum threads and imperial charts from the United States.

Each tool 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 work on a phone with dirty hands.

Something missing? Wheel-nut torque by vehicle, a pressure-washer surface chart and a cornice and skirting mitre calculator are next on the bench.
