Centre Drills

Hi Everyone, Please share some advise.

Which Centre Drills is good for spotting the location for the drilling operation?

I think the answer's in the question! The best form of spotting drill is a spotting drill! Centre drills are intended for drilling holes in the end of a workpiece to take a lathe centre, hence the short projection to clear the point of the centre. Spotting drills are designed specifically for spotting, are much stiffer, less fragile (no delicate tip), and you can get them with angles to match the drills you are using. Plenty around on eBay, etc, or tool supplier of your choice.
