Mitsubishi Materials Solid Carbide Drill for Heat Resistant Alloy Machining DSAS (Internal Coolant Type)

Super heat-resistant alloy machining for a long life. The unique coolant hole shape for drilling diameters of 5 mm or more increases the amount of coolant discharged without reducing drill rigidity, improving lubricity and cooling. Strong straight cutting edge and honing for super heat-resistant alloy machining provide stable chip formation and chipping control. The margin designed for super heat resistant alloy machining minimizes the contact area and suppresses cutting heat and work hardening. The new PVD-coated carbide grade "DP9020" is used to increase hardness while maintaining toughness, improving wear resistance.
For drilling heat-resistant alloys and titanium alloys.
*Coolant holes less than Φ5mm are round. *The color of the coating may look different depending on the viewing direction, but there is no problem with performance. *For stable cutting, it is recommended to supply high-pressure coolant through the coolant. *Emulsion type water-soluble coolant is recommended. *When using water-insoluble cutting fluid, reduce the cutting speed by 10% to 20%. *When machining deeper than DC x 1 with external coolant, step machining of about DC x 0.5D is recommended to break up chips.
