Flat MultiDrill Coated Carbide Drills for Spot Facing MDF Type New 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 dril- ling in inclined and curved surfaces. Advantages Can be used in a variety of drilling applications thanks to its point angle of 180° Applicable to high-efficiency spot facing, drilling in non-horizontal surfaces such as inclined and Improves cylindrical surfaces and interrupted drilling. It also reduces burrs at hole exits. drilling stability by ensuring Improved machining stability web thickness. Achieves high rigidity by employing RS THINNING, which ensures web thickness on the bottom face. Excellent chip evacuation performance Achieves excellent chip evacuation thanks to its wide chip pocket and high-quality rake face shape. Excellent cutting edge strength Achieves excellent cutting edge strength thanks to optimized cutting edge design. THINNING Expanded lineup of long type An expanded lineup of long type drills with diameters between Ø3,0 and Ø20,0mm that are capable of drilling with an overhang length up to L/D=10. Expanded lineup of types with oil hole Supports internal coolant. For deeper drilling (3D, 5D).
