Sumitomo Drill Re-Sharpening or Re-Conditioning


High performance Sumitomo Drill Re-Sharpening or Re-Conditioning services requires a certain amount of skill to do because of the many different and special drill point geometries that are involved in creating a high-end drill. To create the exact geometries and cutting edges to follow the drills original factory specifications takes know how, experience and training in state-of-the-art CNC 7-Axis grinders. Many drill points require such tight tolerances that are smaller than the width of your hair to return them to peak operating efficiency. Kennametal, Mitsubishi, Sandvik are all examples of high end performance tooling that requires a strict discipline and care so that are returned to exact specifications of the factory.

In addition to basic restoration, we can alter the tools geometry to enhance the cutting tools performance within a specific material or application.

Corner radii and chamfers can also be added to not only increase the strength of the tools but also to create special forms as well if required by the prints of the engineers. These added on special forms can save time and money when it comes to reducing the amount of passes or trips. This kind of work can not only be done on used tools but also modified on new tools as well.

Types of tools that can be re-conditioned:

  • Drills
  • End Mills
  • Reamers
  • Countersinks
  • Trepanning Tools
  • Porting Tools
  • Form Tools
  • Counterbores
  • Special Cutting Tools
