Mitsubishi Materials Carbide Flat Drill DFAS for Spot Facing (Internal Coolant Type)

Adopts XR thinning that smoothly curls and rectifies chips, demonstrating low resistance and excellent chip breaking performance. The unique coolant hole shape "TRI-Cooling Technology" increases the amount of coolant discharged without reducing drill rigidity, resulting in significantly improved chip discharge and cutting heat discharge. achieves stable processing. A flat land (gash) is provided at the corner of the cutting edge to ensure strength, and the sharp cutting edge suppresses burrs.
Counterbore processing (slanted surface, curved surface, halving): Ideal for pilot hole drilling for long drills on slanted and curved surfaces. The chipping-resistant cutting edge shape enables various counterboring operations. Drilling (thin plate, cross hole) and hole correction: The flat tip suppresses burrs. Due to its unique shape, it is possible to correct eccentric holes and cast holes with high accuracy.
*For flat surface machining of stainless steel, please use it after countersinking or drilling a pilot hole with the same diameter. *This product is a drilling tool. It cannot be used for traverse processing or helical processing.
