Which? Tapered drill point or step drill?

Hi,
I want to splice 2 dowels together using a male on one piece, as in a pencil sharpener point and a female on the other, as in a cone shape. I know there is a tool for this but it's very expensive for what it does. I have a wood lathe so I would like to insert the dowel in the chuck, and in the tailstock insert a cone cutting drill. Looking on the net I see both types of cutter, step drills and taper drills, as I've never used either, I imagine the taper drill will cut a nice smooth cone shaped hole to match the male point, but what will the step drill cut, a hole with a series of ledges?
Thanks for any advice
Nige

Edit........Or am I totally off the mark here? Is there another tool I could use?

Axminster do a set of tapered drill bits I don't know if they are the sizes you want, but maybe search for tapered drill bit of the size you want.

Can't you use a tapered reamer after drilling a hole with a drill but and the other half turn on the lathe to match

Personally I would look for a scarfed joint as the best result as in pool cue handles as the ideal, next on my list would be the simple step drill one half with the step drill the other half by turning.:fingers::fingers: I see serious flaws in your illustrated joint,

It's the new way they add a piece to a broken arrow to make it up to it's original length, but at over £100 for the cutting machine, I was hoping a tapered drill would do it

Instead of doing a cone joint Nigel could you not drill a straight hole and turn a spigot to suit on joining piece ?

The tapered drill will give you what you want but looking at the pics there's not much timber so the drill might split the shaft when pressure is applied to drill the hole. You'll be drilling end grain.
