Sandvik Coromant 7357693 Replaceable Drill Tip 13.50mm Grade 4334

Product Description

The SANDVIK COROMANT 7357693 is a replaceable drill tip designed for the CoroDrill 870 modular drilling system. It features a 0.5315-inch (13.50 mm) cutting diameter, a 152-degree drill point angle, and a PVD-applied TiAlN coating over a solid carbide, fine-grain substrate. The ISO designation is 870-1350-13-GP 4334, with an insert seat size of 13 and a GP insert geometry. This tip is intended for licensed machinists and tooling professionals working in production drilling environments where repeatable, accurate hole diameters are required across a range of workpiece materials.

This replaceable tip is suited for solid drilling applications on a broad spectrum of workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium — corresponding to ISO material codes P, M, K, N, and S. It is designed for use in CNC machining centers and turning centers where the CoroDrill 870 modular drill body is employed. The clamp-style insert holding method provides secure seating and consistent tool positioning during drilling operations. Typical applications include production drilling in metalworking, aerospace, and general manufacturing environments.

Key Features

• 0.5315-inch (13.50 mm) cutting diameter with 152-degree standard point angle
• Solid carbide, fine-grain substrate for wear resistance and edge integrity
• TiAlN coating applied via PVD process for elevated temperature and abrasion resistance
• GP insert geometry compatible with CoroDrill 870 series drill bodies, seat size 13
• Two-flute helical design with regular spiral for chip evacuation in solid drilling
• Rated for steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium

Compatibility

Designed for use with SANDVIK COROMANT CoroDrill 870 series modular drill bodies requiring an insert seat size 13. The ISO number 870-1350-13-GP 4334 should be used to confirm fitment with the appropriate drill body assembly.

Installation Notes

This replaceable tip is installed and serviced by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and the machine is placed in a locked-out, tagged-out state before tip replacement. Use the designated clamping tool for the CoroDrill 870 system to seat the insert correctly — do not force the tip or substitute fasteners. Inspect the insert seat for chips or contamination before installing a new tip to maintain runout and diameter accuracy.
