Kyocera TCV08012 Ceramic Turning Insert VNGA333T00825

Product Description

The KYOCERA TCV08012 is a ceramic turning insert designed for high-speed, high-temperature machining of hard materials and cast iron. It carries the industry standard designation VNGA333T00825 and the manufacturer grade PT600M, which uses an Al2O3 and TiC Megacoat applied via PVD coating process. The insert features a 35-degree diamond shape, a 3/8-inch inscribed circle, and a 3/64-inch corner radius. With four cutting edges and a neutral hand orientation, it suits a range of turning operations on CNC lathes and turning centers. Licensed machinists and CNC operators working in production environments install this insert in compatible toolholders.

This insert is suited for external turning, facing, copying, and undercutting operations. Primary target workpiece materials are hard materials (ISO material code H) and cast iron (ISO material code K), with material grades K01 and K10. It is classified under ISO code VNGA160412T02025 and meets both ANSI and ISO standards. Applications are typically found in production machining environments where surface finish and tool life on difficult materials are priorities.

Key Features

• Al2O3 and TiC ceramic Megacoat with PVD coating process for wear resistance on hard and abrasive materials
• 35-degree diamond insert shape (shape code V) with four usable cutting edges
• 3/8-inch inscribed circle and 3/64-inch corner radius (0.0469 inches) for precise depth-of-cut control
• Maximum depth of cut of 0.436 inches supports a range of roughing and finishing passes
• Neutral hand designation allows use in both left-hand and right-hand toolholding setups
• Chamfered cutting edge style with negative rake for strength on interrupted cuts and hard materials
• Compatible with clamp and pin insert-holding methods

Compatibility

Designed for use in VNGA-style toolholders that accept a 35-degree diamond insert with a 3/8-inch inscribed circle, 3/16-inch thickness, and a 0.150-inch hole diameter. Consult your toolholder documentation to confirm seating and clamping compatibility before use.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine before changing inserts. Seat the insert fully against the toolholder pocket and verify clamping force with the appropriate torx or hex key as specified by the toolholder manufacturer. Inspect the insert for chips or cracks before each use and replace at first sign of edge breakdown to avoid workpiece damage.
