Tungaloy Updates SNG Line of Internal Grooving Tools

Tungaloy is expanding its SNG line of internal grooving tools to include GMR, a new insert geometry that enables effective chip control and evacuation in internal grooving applications.

Chip evacuation is a major issue with internal grooving. The GMR geometry addresses this by offering a 3D chipbreaker pressed in the cutting edge and optimized rake angle that removes the chip out of the hole and reduces cutting force. This minimizes the risk of chip re-cuts which can cause tool breakage, especially when machining small diameters. This provides improved cycle time and productivity.

Various toolholder sizes are available for internal grooving with a minimum bore diameter (DMIN) of 8 mm (.31″) up to 24 mm (.95″). Carbide shank toolholders are also available for shank diameters of 16 mm (.63″) and smaller for added tool rigidity during long reach applications where vibration control is vital.

At a Glance

  • Superior chip control and evacuation
  • GMR geometry ensures process security in a wide range of parameters
  • Available in AH7025 covering various materials including carbon and alloy steels, stainless steel, as well as heat-resistant alloys
  • Total of 5 inserts to be added
