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