I bought a huge set of drills (bits) recently. Some of the twist drills are plated yellow. they are definitely not TCT masonry drills as they have no rectangular plate brazed into the end.
The packaging says "nn HSS Twist drills and nn Titanium Plated HSS twist drills"
1) I have handled titanium and it is dull grey not yellow
2) What benefit is there supposed to be in plating the drills?
