*A prepared hole with the same diameter or centring hole with a larger diameter than the tool is needed for drilling with the 5D tool.
Recommended Cutting Conditions for 3D 1. The recommended hole depth is 3 x DC. The depth is measured from the highest point of the hole when drilling in inclined surfaces. 2. The recommended cutting conditions are those for drilling in flat horizontal surfaces. 3. Adjust the feed rate according to the inclination angle when drilling in an inclined surface. 4. Set the feed rate at 70% or lower when the inclination angle is 30° or less.
5. Set the feed rate at 50% or lower when the inclination angle is larger than 30°. 6. This product is a drilling tool. Do not use it for traverse cutting or helical milling. 7. A prepared hole with the same diameter is recommended for machining of stainless steel.
