Sandvik Coromant 5747052 Drill Bit 5.56mm Solid Carbide Tialn

Product Description

The SANDVIK COROMANT 5747052 is a screw machine length drill bit engineered for precision hole-making in demanding metalworking applications. Built from solid carbide and finished with a TiAlN coating, this bit delivers heat resistance and extended tool life in high-speed cutting environments. It features a 140-degree split point for accurate self-centering entry and reduced thrust. At 5.56 mm in diameter with an overall length of 2.5984 inches (66 mm), it is sized for short-reach, rigid setups typical of CNC machining centers and screw machine operations. Coolant-through capability supports chip evacuation and thermal management during deep-hole drilling cycles. This bit is part of the CoroDrill Delta-C R840 series and is intended for use by machinists and toolroom professionals.

This drill bit is designed for cutting steel, stainless steel, and cast iron. The 3xD flute-to-diameter ratio and 28 mm flute length make it well suited for shallow-to-moderate depth holes in production environments. Its straight-cylindrical shank at 6.00 mm diameter fits standard drill chucks and collet systems found on CNC turning centers, machining centers, and screw machines. The right-hand cutting direction and regular spiral geometry support consistent chip flow in ferrous materials across both low- and high-volume production runs.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel in accordance with machine tool manufacturer guidelines. Power down and lock out the spindle before loading or changing the bit in any chuck or collet holder. Verify runout and shank seating before beginning a cutting cycle. Confirm coolant lines are active and flowing before engaging the drill in coolant-through applications.
