Magafor S414/5 5-Piece Cobalt Steel Single-End Countersink Assortment, Uncoated (Bright) Finish, Zero Flute, 82 Degrees, Round Shank
The Magafor S414/5 countersink assortment includes five cobalt steel single-end countersinks with an uncoated (bright) finish for creating an 82-degree conical opening that accepts a flat-head fastener so it sits flush with the surface. The zero-flute design has a single flute through the center of the tip, rather than spiraled around the tip, for reduced vibration and a smooth finish in lightweight metals like aluminum and plastic. It is often used for deburring applications. Cobalt steel maintains the tool's toughness and hardness in high drilling temperatures. The uncoated finish has no additional surface treatment or coating. The tools have a single cutting end and a round shank that accommodates most drill chucks. The set comes in a plastic case.
Countersinks are fluted cutting tools that cut a conical or gradually widened opening for a hole into the surface of a workpiece, which provides a seat for a screw or rivet head. They are also used to create center holes for a machine center, deburr surfaces, and enlarging existing holes. The countersink's body diameter should be the same size or larger than what is being countersunk.
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.
