Description:
1. Widely Used on materials such as cast iron, non-ferrous alloys, high silicon aluminum, copper, plastics, hard rubber and other similar materials.
2. Designed for drilling abrasive materials when drilling accuracy must be maintained. Can be used in high temperature drilling applications.
3. Solid Carbide Tool offers long tool life and faster cutting speeds than other substrates, but is more brittle.
4. Must be used with a rigid tool-holding systems. Fine grinding drill obtain accuracy and fine finish than other substrates.
5. Adapt to several kinds of cooling conditions, for example oil mist,water,oil,air cooling.
