The Magafor 154 series high-speed steel combined drill and countersink has a plain style to create a pilot hole with a 82-degree countersink that accepts a flat-head fastener so it sits flush with the surface. The 118-degree conventional 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.
