Hertel 1001149 CCMT3251LF HC210 Carbide Turning Insert

Product Description

The HERTEL 1001149 is a CCMT-style solid carbide turning insert with a PVD-applied TiN coating and a manufacturer grade of HC210. The insert features an 80-degree diamond shape (Insert Shape Code C), a neutral hand orientation, and a positive rake geometry. It measures 9.67 mm (0.3807 inches) in length with a 3/8-inch (0.375-inch) inscribed circle, a 5/32-inch (0.1563-inch) thickness, and a 1/64-inch (0.016-inch) corner radius. The screw-hole diameter is 0.1732 inches (4.40 mm). It belongs to the ModBORE series and is intended for use by machinists and CNC turning operators in precision metalworking environments.

This insert is designed for use in turning and boring operations. Its primary workpiece material designations are M (stainless steel), N (non-ferrous materials), and S (superalloys and heat-resistant alloys), with secondary suitability for K-grade materials (cast iron). Material grades C2 and C4 apply. The T-style chip breaker designation supports controlled chip formation across these material categories. It is suited for both light finishing and moderate roughing passes depending on feed and depth parameters set by the operator.

Key Features

• Solid carbide substrate with PVD TiN coating for wear resistance on stainless, non-ferrous, and superalloy workpieces
• 80-degree diamond insert shape with positive rake for reduced cutting forces
• CCMT insert style with screw-holding method for secure clamping in compatible toolholders
• 1/64-inch (0.016-inch) corner radius for finishing and light-to-moderate cutting applications
• T-style chip breaker for controlled chip management across primary workpiece materials
• Neutral hand orientation for flexible toolholder compatibility

Compatibility

Designed for use in CCMT-style screw-clamp toolholders within the ModBORE series. Compatible with workpiece material grades C2 and C4, with primary material designations M, N, and S, and secondary designation K. Verify toolholder bore diameter and insert seat geometry before installation.

Installation Notes

This insert is installed by a machinist or CNC turning technician using the appropriate torque wrench and screw-clamp toolholder designed for CCMT inserts. Power down and lock out the machine spindle before removing or seating the insert. Inspect the insert pocket and clamping screw for wear or debris before installation. Follow the toolholder manufacturer specifications for clamp screw torque and insert seating procedure.
