The Magafor 1055 series cobalt steel combined drill and countersink has an uncoated (bright) finish, a single end, and a plain style to create a center hole with a 60-degree countersink that can be used as a center hole for machine centers. The 118-degree conventional point drills a center hole, while the two spiral flutes clear chips away to prevent clogging. Cobalt steel provides extended tool life compared to high-speed steel drill bits, and maintains the tool's toughness and hardness in high drilling temperatures. The uncoated finish has no additional surface treatment or coating. The tool has a single cutting end and a round shank that 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.
