Rotary blades
TCG and neutral or negative hook are common in purpose-built nonferrous blades.
Reciprocating and band blades
Bi-metal variable pitch works when section thickness and speed are controlled.
Lubrication
Follow the blade, saw, and workplace rules; some tools prohibit liquid near electrical or dust-collection components.
Method for this decision
- Confirm the alloy form and choose a blade explicitly rated for aluminum and the saw family.
- Clamp the profile, verify hook and RPM, and support the offcut so it cannot rotate or pinch.
- Keep chips moving with a steady feed and inspect for chip welding, grabbing, or hot buildup.
Worked example
Example: a thin aluminum angle can twist into a handheld blade even when its outside size appears small. A restrained hook and firm support address self-feeding; lubrication is a separate manufacturer-approved decision.
Limits and stop conditions
Do not apply liquid near a tool or dust system that forbids it. Aluminum chips can be sharp and hot, and the selector cannot validate an alloy, coating, or machine not represented in the reviewed matrix.
