The HSS-G step drill bit with straight flutes is a versatile solution with good performance and durability for routine sheet metal work, designed to make progressive holes with a single tool.
Made of HSS-G high-speed steel, it allows for stepped diameter enlargement, avoiding the use of multiple drill bits. The straight flute design provides stability during cutting and controlled chip evacuation in thin materials. Its stepped conical geometry facilitates initial centering and improves the hole finish, reducing burrs.
It is designed to offer dimensional precision and repeatability in professional applications.
