The Magafor 125 series high-speed steel combined drill and countersink with uncoated (bright) finish has a radius style to create a center hole with a curved countersink for precision applications. The radius-style countersink creates a protective chamfer and reduces the bearing surface to help maintain a precise center hole and minimize breakage. The 118-degree point drills a center hole, while the two spiral flutes clear chips away to prevent clogging. High-speed steel (HSS) provides hardness for wear resistance, and the uncoated finish has no additional surface treatment or coating. The tool is double-ended to provide two cutting ends. The round shank accommodates most drill chucks.
Combined drill and countersinks are fluted cutting tools that drill a shallow hole with a conical or gradually widened opening, also known as a countersink, into the surface of a workpiece. These tools, also called combined drill countersinks, drill-point countersinks or center drills, are commonly used to create center holes that act as a bearing surface for a machine center. Some types reduce the two-step process of creating a countersunk pilot hole into one.
Magafor manufactures precision cutting tools, including counterbores, countersinks, deburring tools, and end mills. The company, founded in 1937, is headquartered in Fontenay-sous-Bois, France.
