The SGS 56123 is a straight-flute solid carbide drill bit designed for high-precision drilling in ferrous and hardened materials. Built from micrograin carbide with a bright, uncoated finish, it features a 140-degree point angle and a web-thinned geometry that reduces entry force and improves chip evacuation. The two-flute, right-hand cutting design delivers consistent, accurate holes with a diameter tolerance of +0.0000 to -0.0005 inches. With an overall length of 3.0625 inches and a flute length of 1.75 inches, it fits standard drill chucks and CNC machining setups. This bit is intended for use by machinists and tool-and-die professionals working in production or job-shop environments.
The SGS 56123 is suited for drilling cast iron, steel, and hardened steel, as well as other hardened materials where carbide tooling is required. It carries a 3xD flute-by-diameter ratio and a maximum drilling depth of 1.406 inches, making it appropriate for short to medium depth holes in demanding applications. The straight-flute configuration is particularly effective in brittle materials such as cast iron where a straight flute controls chip breakage better than a spiral flute. It conforms to DIN 6539 standards and is sold individually.
Designed as an OEM-style replacement or direct-use straight-flute carbide drill bit for machining operations involving cast iron, steel, hardened steel, and hardened materials per Series 106 specifications.
Installation and use should be performed by qualified machinists familiar with carbide tooling requirements. Secure the shank fully in the drill chuck or collet before operation and verify runout is within acceptable limits before drilling. Carbide drill bits are brittle and should not be subjected to lateral loading or impact. Power down and de-energize all equipment before tool changes.
