Sandvik Coromant 6633714 Indexable Drill Insert 880GM

Product Description

The SANDVIK COROMANT 6633714 is a solid carbide indexable drill insert designed for use in indexable insert drills in metal-cutting applications. Carrying the 880GM chipbreaker geometry and manufacturer grade 4334, this square-shaped insert features a multi-layer TiCN/Al2O3/TiN coating applied via the CWD process, delivering wear resistance and thermal stability in demanding drilling operations. The inscribed circle measures 8.90 mm (0.3504 inches), thickness is 0.1181 inches, and the corner radius is 0.50 mm (0.0197 inches). This insert is a right-hand cutting-direction component suited for high-productivity drilling in steel and other common workpiece materials.

This insert is used in indexable drill toolholders that accept the 880 insert style with a 05P insert size designation. Typical applications include through-hole and blind-hole drilling on CNC machining centers and turning centers in metalworking shops, manufacturing facilities, and job shops. The square insert shape and GM chipbreaker make it particularly effective in general-purpose drilling of steel workpieces where controlled chip formation is a priority. The mounting hole diameter is 3.20 mm (0.1260 inches), confirming fitment to compatible 880-series drill bodies.

Key Features

• Solid carbide substrate with multi-layer TiCN/Al2O3/TiN coating via CWD process for extended tool life

• Manufacturer grade 4334 optimized for steel and general-purpose metal cutting
• Square insert shape, right-hand cutting direction
• 0.50 mm corner radius minimizes chipping at the cutting edge
• Inscribed circle of 8.90 mm (0.3504 inches), insert size 05P

Compatibility

Designed as a replacement insert for 880-series indexable drill bodies accepting a square, 05P insert size with a 3.20 mm mounting hole diameter. Confirm toolholder seat specifications before ordering.

Installation Notes

This insert is installed by machinists and tooling technicians on CNC or manual machine tools. Always power down and lock out the spindle before changing inserts. Use the correct torx or hex key at the recommended seating torque for the toolholder manufacturer's specification — do not exceed or estimate fastener torque. Inspect the insert pocket and seating surface for debris or damage before installation to ensure proper insert contact and cutting-edge alignment.
