What is good for Jobber Length Drill Bits ?


All Jobber Length Drill Bits have Split Points and come in two different materials. These high performance twist drill bits are suitable for all normal drilling in conventional materials.

  • Available in High Speed Steel and Titanium Nitride-coated (TiN-coated) High Speed Steel (HSS),

  • The added titanium nitride coating increases the surface hardness to approximately 2300 HV and the heat resistance to 1100°F (600°C).

  • 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

What kind of drill bit do you prefer ? You decide!


  • The HSS ground twist drill bit is made of heavy-duty high-speed steel.
  • The fully ground twist drill bit has a more precise concentricity.

  • HSS-TiN models add a titanium nitride coating, to increase the surface hardness and the heat resistance.

  • The titanium nitride coating also provides longer tool life with increased cutting speeds
