Hertel HTVCMX332420CD Pcd Turning Insert 3/8 Inch Ic

Product Description

The HERTEL HTVCMX332420CD is a Polycrystalline Diamond (PCD) turning insert designed for precision single-point turning operations on CNC and manual lathes. Manufactured to HT-VCMX insert style standards, this insert features a diamond (V) shape with a 3/8-inch inscribed circle (IC) and a 1/32-inch corner radius. The PCD cutting material provides extreme hardness and wear resistance suited for high-speed finishing passes on non-ferrous metals, composites, and abrasive materials. The uncoated PCD construction delivers consistent edge sharpness without the variable performance associated with coated grades. Holding method is screw-on, and the insert carries clearance code C and tolerance code M, corresponding to standard industry fit classifications. Material grade is C2.

This insert is applied in high-speed turning of aluminum alloys, copper, brass, carbon fiber reinforced composites, and other non-ferrous or abrasive workpiece materials where carbide tooling wears rapidly. Typical installation environments include production CNC turning centers and manual engine lathes where tight surface finish and dimensional tolerances are required. The HT-VCMX insert style seats into compatible VCMX-style toolholders. It is commonly used by machinists and tooling technicians in aerospace, automotive, and general precision machining shops. Chip breaker designation is X and insert size code is 332, consistent with ANSI insert identification conventions.

Key Features

• Polycrystalline Diamond (PCD) insert material for superior wear resistance on non-ferrous and abrasive materials
• Diamond (V) insert shape with 3/8-inch inscribed circle for flexible toolpath engagement
• 1/32-inch (0.0313 inch) corner radius for fine finishing cuts
• Uncoated construction maintains consistent PCD edge geometry throughout tool life
• Screw-on insert holding method for secure, repeatable seating in compatible toolholders
• Tolerance code M and clearance code C conforming to standard ANSI insert classifications

Compatibility

Designed for use in HT-VCMX-style screw-on turning toolholders that accept a 332-size diamond (V) shape insert with a 0.1730-inch hole diameter. Verify toolholder pocket dimensions and clamp style before installation.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before changing inserts. Use the appropriate torque screwdriver or insert key specified by the toolholder manufacturer to secure the clamping screw — avoid over-tightening, which can crack the PCD blank. Inspect the toolholder pocket for chips or debris before seating the insert, and confirm proper insert orientation relative to the cutting direction before resuming operation.
