Workpiece rigidity StableUnstable Enhanced drill head variations for higher performance DMP Drill head - general purpose Unique edge preparation Close-up of edges (new head) No peeling-off Radius honing Effectively improves Peeling-off adhesion strength - Versatile drill head - Suited for various materials and applications - Light cutting due to sharp cutting edge Chamfered honing Competitor DMH with optimized edge preparation for edge toughness Applicatiion range of DMH DMP DMH 0 0.5 Strong cutting edge design Carbon content of steel (%) - Strong cutting edge design prevents the drill edge from fracturing during demanding processes - Versatile and wear-resistant AH9130 grade provides extended tool life DMC Drill head - high accuracy drilling DMC Quick-centering profile Double margins Stability Competitor - Innovative chiseled edge for smooth drill entry. No pre-drilling needed in 12xD drilling operation - Superior hole diameter accuracy and circularity - Double margins provides superior surface finish and hole drilling straightness Chatter Parameters : Vc =100 m/min, f = 0.3 mm/rev Drill diameter : ø13, L/D = 12 (No pilot hole) Materials : S55C DMF DrillMeister flat head Pilot edge 180° flat cutting edges supports smooth entry to work piece produces holes with Shoulder chamfer flat bottom. Ideal for prevents premature fracture counterboring for bolt heads. - Flat edge design with pilot edge performs balanced drill entry - Significantly reduced radial forces promise stable drilling for complex surfaces at drill entry and exit - Stable drilling with long overhang up to L/D = 8 without pre-hole 8-4
