CoroDrill® 870

CoroDrill® 870 exchangeable-tip drill saves time, increases productivity and reduces cost per hole. Tailored to suit your needs, CoroDrill 870 is designed to optimize applications through diameter range, steps and length possibilities for the H9-H10 hole-tolerance area.

Optimized for long predictable tool life and high productivity

The CoroDrill 870 drill body is designed for high penetration rates and excellent hole quality. Chip flutes have optimized shape, size and helix angle for safe chip evacuation and tool stability.

Grades have predictable wear patterns for long and reliable tool life at high productivity rates.

Geometries showcase high process security, good chip control, high penetration rates and premium hole quality.

Tailored for your needs

The CoroDrill 870 comes in an extensive standard offering. However, when standard isn’t enough both drill body and tips can be further optimized using Tailor Made or Engineering services.

Among others, the Tailor Made options available include:

  • Longer drills
  • Step & chamfer drills
  • Optimized drill bodies
  • Geometry alterations

Easy handling and productive tip changes

The high precision interface between drill body and tip provides accuracy, security and stability in drilling applications.

Designed for productivity, the interface allows for changing of tips while remaining in the machine, reducing downtime.
