Taper Drilling Notes -
1. Speeds and feeds should be between 40% and 50% of those recommended for a parallel drill equal to the large diameter of the taper
Drill. The amount of work required of a taper drill is very large and the power requirement is therefore very high.
2. The Nominal size of a 1 in 50 drill is measured at the small end; in the case of 1 in 48, it is measured at the large end.
Special taper drills may be manufactured to order. The unit price will depend upon the quantity, and full details will be required
