TiN COATED DRILL BITS

TITANIUM NITRIDE COATED

The TiN Coated drill bit is treated with a Titanium Nitride surface treatment that lends a super hard, protective layer to the drill bit without increasing brittleness. The treated surface is incredibly hard and possesses superior lubricity. The tool life may be extended 500% or more in high wear or very abrasive drilling applications. The Titanium Nitride coating also reduces friction and chip welding, and acts as a thermal insulator between the chip and the tool. Recommended for use in hard metals (up to RC40), work hardened stainless, and other difficult to drill or abrasive non-ferrous materials.

Titanium Nitride Coated Drill Bits

  • TiN TIPPED BITS:

    TiN coated tip only keeps cost per bit down while still benefiting from TiN surface treatment. Standard length drill bits. Shank diameter equal to drill diameter. The 135 degree Split Point eliminates walking at the drill point, reduces thrust, and eliminates the need to pre-drill.

    • FEEDS AND SPEEDS

      RECOMMENDED FEED RATES AND SPEED:

      Drill Bit Recommended Feed Rates and Speeds

      Feeds – Feed rates for drilling are governed by the drill diameter, machinability of materials and depth of hole. Speeds – The speed of a drill is determined by the rate which the outer periphery of the tool rotates in relation to material being cut. In general, the SFM at which a drill will operate is within a range based upon the workpiece material, its condition, hardness and depth of hole. It is usually advisable to start the drilling process at a slower SFM and then increase to the maximum.
      RPM = SFM/TD x 3.82 = Revolutions Per Minute
      SFM = RPM x TD x .26 = Surface Feet Per Minute
      TD = Tool diameter in inches
