300W is pretty small. Slow feed won't kill your spindle but can cause overheat problems and shorted bit life.
Take some time to understand feeds and speeds. That's an overlooked area for a lot of beginners. Each bit and material has an optimal chip load. Load is based on the number of flutes, spindle speed and feed rate. Too low and you have rubbing and friction. Too high and you stress the motor and/or frame. Plus, you can get a very poor cut and broken bits. Look to the bit manufacturer for feed and speed recommendations.
The thing you will need to figure out on your own is how much of a depth of cut your machine will allow. It has to do with the spindle but also with how rigid your machine is. The cheap Chinese machines are notorious for flexing under load which means poor cut quality. You compensate by using a shallow DOC with multiple passes and thus a much slower process.
I'd start out fairly conservative and then move up. Can you control spindle speed? If you can't get a high feed rate, you can cut your spindle speed. You can also go to a single flute bit which doubles your chip load.
Also, I've never seen a 1/8" shank V Bit with a half inch diameter cutter. Where did you get it?
