Different surface treatment of HSS drill bits
Black Oxide---is an inexpensive black coating.A black oxide coating provides heat resistance and lubricity,as well as corrosion resistance.Coating increases the life of HSS bits.
Tianium Nitride(TIN)---is a very hard ceramic material that can be used to coat a high speed steel bit(usually a twist bit),extending the cutting life by three or more time.However, when the bit is sharpened the new edge,will not have the benefits of the coating.
Cobalt drill bits---are specially designed for drilling in hard steel,thick web helix delivers fast material removal combined with increased durability for maximum officiency and performance. Each bit is manufactured to exacting specifications and features a split point that starts on contact with no walking or skating,eliminating the need for a center punch.
