Sandvik Coromant 7357966 Replaceable Drill Tip 0.7677 in

Product Description

The SANDVIK COROMANT 7357966 is a replaceable drill tip designed for use with the CoroDrill 870 modular drilling system. This solid carbide insert features a 0.7677-inch (19.00 mm) cutting diameter, a 142-degree point angle, and a TiAlN coating applied via PVD process. It carries Manufacturer Grade 4334 with a fine-grain carbide substrate. The PM insert geometry and helical flute design support stable chip evacuation during solid drilling operations. Installation is accomplished via clamp-style insert holding, making tip changes fast and repeatable at the spindle without pulling the drill body from the machine.

This drill tip is suited for solid drilling applications across a broad range of workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, and superalloys and titanium. It is identified by ISO material codes P, M, K, N, and S. The CoroDrill 870 platform is common in production machining environments — both job shops and high-volume manufacturing — where replaceable-tip drills reduce tooling cost per hole while maintaining consistent entry and exit geometry. A licensed machinist or CNC tooling technician typically handles installation and changeover.

Key Features

• Solid carbide fine-grain substrate for wear resistance across P, M, K, N, and S material groups
• TiAlN coating via PVD process for thermal and oxidation resistance at the cutting edge
• 142-degree point angle with PM insert geometry for controlled entry and chip formation
• Helical, regular-spiral flute design with 9.00 mm flute length supports chip evacuation
• Clamp-style insert holding for quick, repeatable tip indexing without full tool removal
• Insert Seat Size 19 for direct compatibility with matching CoroDrill 870 drill bodies

Compatibility

Designed for use with SANDVIK COROMANT CoroDrill 870 drill bodies accepting Insert Seat Size 19. ISO Number for this tip is 870-1950-19-PM 4334. Verify seat size and series designation on the drill body before ordering.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and all energy is isolated before handling inserts. Seat mating surfaces should be clean and free of chips or debris before clamping the tip in place. Follow the tool manufacturer torque guidance for the clamping screw; do not use impact drivers on insert clamp fasteners.
