Sandvik Coromant 5747390 Carbide Jobber Drill 5.40mm

Product Description

The SANDVIK COROMANT 5747390 is a solid carbide jobber-length drill bit designed for high-performance hole-making in demanding metalworking applications. Built on the Series R840 platform, it features a 5.40 mm (0.2165 inch) cutting diameter, a 140-degree self-centering point, and a TiAlN coating that extends tool life in abrasive and high-temperature cutting conditions. The two-flute spiral design with coolant-through capability supports chip evacuation and heat management during deep drilling cycles. Overall length is 2.5984 inches with a 6.00 mm straight-cylindrical shank. This drill is specified to DIN 6535HA and carries a micrograin carbide grade for edge stability under high feed rates.

The 5747390 is rated for drilling into a broad range of workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. Its 5xD flute-to-diameter ratio supports a maximum drilling depth of 19.00 mm (1.1024 inches), making it well suited for production environments where consistent hole quality in tough alloys is required. The self-centering point geometry reduces the need for a pilot hole in most setups, improving cycle time on CNC machining centers and manual drill presses alike. Machinists and toolroom technicians working in aerospace, general metalworking, and heavy manufacturing will find this drill a direct fit for those applications.

Key Features

• Solid carbide construction with micrograin grade for high edge retention in ferrous and non-ferrous materials
• TiAlN coating provides thermal and oxidation resistance for extended tool life
• 140-degree self-centering point reduces walk and eliminates pilot drilling in most applications
• Coolant-through design supports chip evacuation and heat control at full drilling depth
• DIN 6535HA specification ensures dimensional consistency and machine-tool compatibility
• 5xD flute ratio with regular spiral geometry for reliable chip clearance up to 19.00 mm depth

Compatibility

Designed as an OEM-specification replacement or new-application drill for use in CNC machining centers and drill presses accepting a 6.00 mm straight-cylindrical shank per DIN 6535HA. Compatible workpiece material codes P, M, K, N, and S are confirmed by the manufacturer for this series.

Installation Notes

Installation and use should be performed by a qualified machinist or toolroom technician familiar with carbide tooling. Ensure the spindle and collet or chuck are clean and free of runout before seating the shank, as carbide is brittle and sensitive to lateral loading caused by excessive runout. Verify coolant-through supply is active before beginning the drilling cycle when using internal coolant passages. Follow machine-tool manufacturer guidelines for feed rate and spindle speed when transitioning to a new workpiece material.
