Product Description

The Magafor 434 series cobalt steel countersink with uncoated (bright) finish creates an 82-degree conical opening that accepts a flat-head fastener so it sits flush with the surface. The three flutes clear chips away to prevent clogging. Cobalt steel provides extended tool life compared to high-speed steel when cutting hard materials, 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.

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.

Works like a charm! Smooth, quick countersinks form Al all the way to SS! The low flute height allowed me to get in some tight spaces. Chip removal was quick with no binding or chatter. I've used a 1/4" hex shank adapter with this to allow me to quick change it in and out on my electric screw gun.
