AddInternalCut Indexable Internal Grooving Tool System

Tungaloy has expanded its AddInternalCut indexable internal grooving tool system by increased insert width options.

AddInternalCut internal grooving tool line features ground-to-precision inserts with four economical cutting edges. Unique and strong insert holding system provides tool rigidity and smooth chip evacuation, ensuring superior edge repeatability and precision machining.

The insert is clamped in the seat so that, in case the cutting edge is broken during machining, the remaining un-used cutting edges are protected, allowing all four edges to be effectively used. Being supported at three points when clamped in the seat, the insert provides accurate insert position repeatability and stable performance even in high speed and feed rate conditions. Furthermore, the insert is double sided and can be mounted on either a right- or left-hand toolholder, allowing easy inventory management.

AddInternalCut inserts are available in two sizes: TCIG10 insert is for internal grooving of minimum bore diameter of 10.5 millimeters (.413 inches) and up. TCIG12 allows a maximum groove depth (CDX) of 3.0 millimeters (.118 inches).

The newly introduced AddInternalCut grooving inserts are capable of cutting extremely thin internal grooves of 0.5 millimeters (.020 inches), as well as groove widths from 1.22 to 2.77 millimeters (from .048 to .109 inches), covering industry-standard groove profiles such as circlips and o rings.

Related Glossary Terms

  • feed


    Rate of change of position of the tool as a whole, relative to the workpiece while cutting.

  • grooving


    Machining grooves and shallow channels. Example: grooving ball-bearing raceways. Typically performed by tools that are capable of light cuts at high feed rates. Imparts high-quality finish.

  • precision machining ( precision measurement)

    precision machining ( precision measurement)

    Machining and measuring to exacting standards. Four basic considerations are: dimensions, or geometrical characteristics such as lengths, angles and diameters of which the sizes are numerically specified; limits, or the maximum and minimum sizes permissible for a specified dimension; tolerances, or the total permissible variations in size; and allowances, or the prescribed differences in dimensions between mating parts.

  • toolholder


    Secures a cutting tool during a machining operation. Basic types include block, cartridge, chuck, collet, fixed, modular, quick-change and rotating.
