Competitor

- Innovative chiseled edge for smooth drill entry. No pre-drilling needed in 12xD drilling operation - Superior hole diameter accuracy and circularity ChatterChatter - Double margins provides superior surface finish and hole drilling straightness 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
