• General Features The flat multidrill MDF type is a solid carbide drill that can be used for various purposes including high-efficiency spot facing and drilling on inclined or curved surfaces.

• Characteristics and Applications
• Applicable to various types of drilling thanks to a point angle of 180° Applicable to high-efficiency spot facing, drilling in non-flat surfaces such as inclined and cylindrical surfaces, and interrupted drilling. Also reduces burrs at the hole exit.

Improves drilling stability

• Improves machining stability

by ensuring web thickness Achieves high rigidity by RS THINNING, which ensures thick web at the bottom.

• Excellent chip evacuation Achieves excellent chip evacuation thanks to the wide chip pocket and a high-quality rake face shape.
• Excellent cutting edge strength Achieves excellent cutting edge strength through optimized cutting edge design.
• Drills with longer shank Lineup of ø3.0 to 20.0mm drills with longer shank, for drilling with long overhang up to L/D=10.
• Drills with oil-holes Achieving deeper drilling with internal cooling.
• Reduction of Burrs at Hole Exit
