High Speed Steel (HSS) TiN Coated - Fractional sizes
All Jobber Length Drill Bits and Step Drill Bits have Split Points and come in two different materials:
- The Split Point reduces “walking” which is the tendency of a spinning bit to rotate away from the point at which you want to drill
- The High Speed Steel (HSS) allows the bit to cut faster than High Carbon Steel. At room temperature, HSS and high carbon steel have an equivalent hardness; at elevated temperatures, HSS become advantageous
- The Titanium Nitride (TiN) coating is an extremely hard ceramic. It is often used as a coating on HSS to improve hardness and durability
