Workshop and Tool Setup Calculations
Setting up machinery and tools correctly is essential for both safety and quality results. Running a router bit too fast can burn the wood; running a lathe too fast with a large blank is dangerous. These calculators help you find the right settings every time.
Router bit speed depends on the bit diameter — larger bits must run slower to keep the cutting edge at a safe peripheral speed. Our router bit speed calculator determines the correct RPM range for any bit size, following manufacturer guidelines for safe operation.
Workshop dust extraction is critical for health and safety. Different machines produce different volumes of dust and chips, and your extraction system needs adequate CFM (cubic feet per minute) to handle the worst case. Our dust collection calculator works out your total CFM requirements and recommends duct sizing based on your machine layout.
When your band saw blade breaks, you need to know the exact replacement length. Our band saw blade length calculator calculates blade length from wheel diameter and centre-to-centre distance, so you can order the correct blade without removing and measuring the old one.
