From the figures alone, it should be fine.
The only thing to possibly be wary of, if the new one seems too small for the stated power, is if it has a "Duty cycle" rating on it, less than 100%? Some applications only allow a motor to run for a short time then it can cool down for a while, or only occasionally put it under high load, so the motor does not have to be big enough to continuously dissipate the full heat it produces when working hard..
It may just be that the original motor is an older design and over-size by comparison to newer types.. Without full data it's a bit of guesswork.
As long as the motor speeds are compatible, I'd say just try it and keep any eye on the motor temperature while cutting, to start with.
