Trimmer rotation speed

388 Views 7 Replies 7 Participants Last post by  woodnthings
Hello ! I have an wood trimmer which works at 32000 rpm (no load speed) and I need some 6mm trim heads. I found on the internet the necessary trim heads but they were 24000 rpm. Also I found on the internet some trim heads that doesn't specify the maximum rpm.
I am wondering if the mentioned trim heads can be used for my trimmer ?
The trimmer is a Makita 3711.

Could be wrong, but I've never heard of any router bits not being able to be used with any known router. If you have doubts, check with the manufacturer.
I don't know the difference between a trimmer and a compact router. I don't recall routers with a RPM that high. Maybe there are 6mm router bits that can't handle the trimmer?

@mike_9 please post a link to the trimmer head you are thinking of.
This is the bit set that doesn't specify the rotation speed: 12PC/Router Bit
And this is the bit set from Hikoki: HIKOKI 711016 hm milling cutter set 6 mm (12 pcs.) | Klium
And this is the one from Makita: D-09488 - CAP DE FREZAT 45 which say on the online shop that is 24000 rpm maximum.
"No load" speed is not a useable number. Rev a motor car engine to "no load" speed and it will go all around the tacho before blowing up. Running any router at "no load" speed for any length of time will also damage the motor.
The resistance of the bit alone will reduce the revs considerably.
You can prove this easily. With no bit in the router, switch it on for a couple of seconds and listen to the motor noise. Very high pitched. Put a bit in it and again switch it on briefly, lower pitch. Run it along a length of wood and listen again, the lower the pitch of sound, the lower the motor speed.
Nobody would start up a trim router with a bit and then leave it running on the bench.
I dont believe you have a problem.
