Above cutting conditions are for drilling flat surface. In case of drilling slope, the figure to be adjusted as below: For inclined angle under 30, reduce Feed speed (Vf) to 40-80%, and for inclined angle 30 or more, reduce Feed speed (Vf) to 20-50%. 2. In case of using shank 6 type (TLDM***-S6 type), recommend applying lower cutting conditions. 3. Above cutting conditions are for drilling with water soluble. In case of dry cutting, use air blow to remove the chips. 4. Recommend drilling depth under 2D or less. Drilling depth over 2D is not recommended. 5. Horizontal milling is impossible. 6. In case of machining heat-resistant alloy, using 0.5mm step feed. 7. In case of long chips evacuated, adjust above conditions by increasing Feed speed or using step feed for breaking chips. 10
