Bit length on my king palm router

Hi!

I want to make mortises in red cedar 2x4. I have a upcut spiral bit witch is 3 inches long. My problem is that the bit enter only 5/8 “ in the collar and the distance between the collar and the bottom of the plate is only 1 5/8”. This leaves me with a possible bit length of 2 1/4 inch. I can cheat for a 1/4 “ if I don’t push the body of the router fully in the plunger but I don’t know if it is safe both for the tool and myself.
I tried to find shorter upcut bit but couldn’t find anything shorter than 2 1/2“.
what would you do?

thanks

Unusual for the shaft of the bit to only go into the collet for 5/8”. Check that there is no obstruction. I would say definitely unsafe to have a 3” bit with only 5/8” inside the collet.

The collet length is 5/8”. The bit don’t want to pass through more.

I have another idea: if I build a ticker jig attached to my base, the 2 1/2” bit could do the job. I found the 75-103 Freud bit that is 2 “ long but more expensive than 2 1/2”.
what do you think of my idea?

I belive the newer cutters have K mark on the side to show how deep to inesrt the cutter into the collet.

Does you cutter have this mark?

A picture worth thousand words.

for sure this bit is much too long. This collar is small for the use I intend for this router.

Tool Wood Rectangle Office ruler Ruler

Automotive tire Wood Machine tool Gas Workbench

This 3 “ bit protrude 3/4“ from the plate.
I wonder if I can buy a 2 1/2” bit and thicken the plate to gain the 1/4”.

This cutter doesn’t have a Kmark. ( by the way it have rusted marks from my other router)

I agree. the forces acting on that bit, spinning at such high speed, will be tremendous. You don't want to be anywhere near if that thing gets spit out of the collet.

What was your other router?
Did it fit properly in the other router?
Have you used the cutter in the other router.

I agree with the other memebers, that the cutter should go in further than that,

I would not use it in this configeration.

@domi125
on my routers with a similar collet style, the shaft of the bit can slide right through the end of the collet, to reach the bottom of the hollowed-out shaft of the motor (minus the recommended 1/8 “). If your bit can slide through, the router is simply not designed for the task you have in mind, but for edge routing.
If it cannot slide through, there may be some defect of shaft or collet. Either way, play it safe, don’t use..

Did it fit properly in the other router? It fits perfectly and slides easily
Have you used the cutter in the other router. Yes I made a lot of mortises

Me too

It cannot slide through and it jam inside the collet that I nee an unusual force to pull it out . I made a call to the company. They will send me a new collet. Probably I received a metric collet ( 6 mm instead of 6,35 mm).
