Multi-Drills Flat MultiDrill MDF Type Coated Carbide Drills for Spot Facing 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 in inclined and curved surfaces. I 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 cylindrical surfaces and interrupted drilling. It also reduces burrs at hole exits. Improved machining stability 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. Expanded lineup of long type An expanded lineup of long type drills with diameters between 03,0 and 020,0mm 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). Improves drilling stability by ensuring web thickness. . th RS THINNING Reduction of Burrs at Hole Exit Work Material: 15CrMo5 Drill: MDF0500S2D (05,0mm 2D) Cutting Conditions: vc = 65m/min, f = 0,12mm/rev H = 10mm, 150 holes, wet Equipment: Vertical machining center Reduces exit burrs by more than half compared to general-purpose drills Burr height: 0,18mm Flat MultiDrill MDF type Burr height: 0,44mm Conventional general type Applications High-efficient spot facing Hole expansion drilling Drilling in non-horizontal surfaces (such as inclined and cylindrical) Jl Interrupted drilling Long Type I 11 Pre-tap hole drilling in thin sheets Deep spot facing Avoiding interference with work materials K28
