Sgs 56474 9/64 in Taper Length Drill Bit Solid Carbide

Product Description

The SGS 56474 is a taper length drill bit engineered for high-performance drilling in a wide range of materials. Built from micrograin solid carbide and finished with a Ti-NAMITE-X (TX) coating, it delivers extended tool life and thermal resistance under demanding conditions. The 135-degree split point reduces walking at entry and requires no center punch on most surfaces. With a right-hand spiral flute and web-thinned geometry, this bit clears chips efficiently throughout the cut. Through-coolant capability supports high-speed machining in both CNC and manual setups. It conforms to DIN 6537 specifications and is rated for universal material application.

The 56474 is suited for precision metalworking, toolroom, and production machining environments where tight-tolerance holes are required. The 8xD flute-to-diameter ratio accommodates deeper drilling passes without tool change. A straight cylindrical shank with a 1-49/64 inch shank length seats cleanly in standard drill chucks and collet holders. This bit is appropriate for aerospace, automotive, fabrication, and general machine shop applications requiring consistent, repeatable hole quality in steel, stainless, aluminum, and similar materials.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance
• Ti-NAMITE-X (TX) coating provides heat resistance and extended cutting life
• 135-degree split point reduces entry force and eliminates walk
• Web-thinned geometry improves chip evacuation and reduces thrust
• Through-coolant capable for high-speed and deep-hole applications
• Conforms to DIN 6537 specification for dimensional consistency

Compatibility

Designed as an OEM-style taper length drill bit for use in standard drill chucks and collet systems accepting a straight cylindrical shank, suitable for universal material applications per Series 142P specifications.

Installation Notes

Installation and tool changes should be performed by qualified machinists or tool and die professionals with the spindle fully stopped and machine power isolated. Seat the cylindrical shank fully in the chuck or collet and verify runout before cutting. Through-coolant systems should be purged and confirmed operational before engaging the workpiece. Follow applicable shop safety standards and machine manufacturer guidelines for speed and feed selection.
