Had to replace my router because of a user error and a ruined bearing. Anyway, I was wondering what is the recommended way to tighten the bit/collet nut? Two tools are provided, although one of them tends to bend very easily. Do you use the two tools or the button and one tool to tighten the nut?
I refuse to use the hard cheese disguised as a spanner that comes with most routers.
Using the button to hold the spindle is fine, when the router is off the CNC.
I use a proper spanner on the collet nut either way. To avoid pushing the spindle around trying to tighten, it can be easier to use a pair of spanners on the collet. Sometimes you can only fit a narrow spanner into the flats on the spindle, I find Park Tool make nice quality thin spanners for bike maintenance.

Only use the button to hand-tighten so that things will stay in place while one fully tightens using a good quality pair of wrenches.
Standard Carbide Compact Router/Makita RT0700/0700 collet wrench/nut sizes:

- Bicycle cone wrenches work as well such as the 13mm Park Tool PT-09 Shop Cone Wrench
- Asahi low profile 11/13mm wrench
- McMaster-Carr Tight-Clearance Open-End Wrench with Black Finish, 13 mm Size, 4" Overall Length (sourced from Martin as of mid-2020)
- 22mm — a stubby wrench is well-suited for this, and handier due to the low torque requirements
