Gundrill and Deep Drilling Heads Carrying Inserts with 3 Edges

The TOGT inserts feature 3 chip splitting cutting edges, a positive rake chip breaker and a wiper for high hole surface quality. The new inserts are available in 5 sizes, made from IC908, a versatile PVD coated grade. 

Features

  • The only deep drills with a 3 cutting edged insert (other manufacturers only offer inserts with 1 or 2 cutting edges)
  • Highly accurate peripherally ground insert, provides high hole diameter accuracy of IT10
  • The chip splitter produces narrow chips for efficient chip evacuation, enabling higher feed rates compared to other drills available in the market
  • A wiper on the insert provides extra fine surface finish
  • Direct insert mount - no adjustment needed for accurate hole diameter
  • The drills can carry the new economic solid carbide or the brazed guide pads

Related Glossary Terms

  • feed

    feed

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

  • physical vapor deposition ( PVD)

    physical vapor deposition ( PVD)

    Tool-coating process performed at low temperature (500° C), compared to chemical vapor deposition (1,000° C). Employs electric field to generate necessary heat for depositing coating on a tool’s surface. See CVD, chemical vapor deposition.

  • rake

    rake

    Angle of inclination between the face of the cutting tool and the workpiece. If the face of the tool lies in a plane through the axis of the workpiece, the tool is said to have a neutral, or zero, rake. If the inclination of the tool face makes the cutting edge more acute than when the rake angle is zero, the rake is positive. If the inclination of the tool face makes the cutting edge less acute or more blunt than when the rake angle is zero, the rake is negative.

  • wiper

    wiper

    Metal-removing edge on the face of a cutter that travels in a plane perpendicular to the axis. It is the edge that sweeps the machined surface. The flat should be as wide as the feed per revolution of the cutter. This allows any given insert to wipe the entire workpiece surface and impart a fine surface finish at a high feed rate.
