Extreme Wear Resistance
Polycrystalline diamond composite construction handles high processing speeds while resisting abrasive adhesive lines and core voids.


Premium Polycrystalline Diamond (PCD) exchangeable insert knife for industrial WhisperCut jointing and pre-milling cutterhead assemblies. Engineered with a targeted 3mm thickness for highly precise, ultra-quiet panel profiling.
This genuine Leitz exchangeable insert brings structural diamond longevity to high-performance sizing systems working abrasive laminates and composite panels.
Direct pocket-seat compatibility for Leitz WhisperCut sizing, jointing, and industrial edgebander pre-milling systems.
The Leitz WhisperCut Type B exchangeable polycrystalline diamond (PCD) knife is a critical component for achieving perfect, tear-free board preparation in industrial panel processing. Measuring 14 mm in length, 14.2 mm in width, and specialized at a 3 mm thickness, this high-performance insert fits tightly into WhisperCut cutterhead pocket architectures to eliminate micro-vibrations and runout errors during high-speed feed cycles.
Designed to cope with the severe abrasive demands of resin-bonded particleboard, medium-density fiberboard (MDF), and delicate decorative surface skins, the PCD cutting matrix maintains razor-sharp edge geometry significantly longer than standard carbide. This ensures clean, uniform material removal, providing a perfectly square, chip-free joint line critical for flawless laser, hot-air, or PUR edgebanding applications.
Sustain maximum line throughput and flawless finish accuracy with the genuine Leitz WhisperCut Type B 14x14.2x3 PCD knife insert. Tailored for heavy-duty woodworking applications and intensive high-speed panel formatting lines, this premium tool component ensures your edge pre-milling process maintains maximum precision shift after shift.
Technical Specifications
Polycrystalline diamond composite construction handles high processing speeds while resisting abrasive adhesive lines and core voids.
Machined to explicit 3mm depth profiles to ensure weight-matched balancing tolerances across high-RPM cutterhead bodies.
Optimized clearance angles deliver crisp cutting action, eliminating face breakout and core delamination on delicate panels.
Verify that your current Leitz cutterhead assembly specifies a 3mm thickness profile insert (SKU 091066) rather than alternative 4.3mm variants before purchase. Prior to mounting new inserts, carefully clear all resin deposits and particulates from the pocket seats. Use factory-calibrated torque keys to secure the clamping wedge to exact manufacturer tolerances, mitigating tool strain and maintaining optimal radial runout tracking.
Sustain maximum line throughput and flawless finish accuracy with the genuine Leitz WhisperCut Type B 14x14.2x3 PCD knife insert. Tailored for heavy-duty woodworking applications and intensive high-speed panel formatting lines, this premium tool component ensures your edge pre-milling process maintains maximum precision shift after shift.
The highly stable PCD cutting layer acts seamlessly across dense particle structures, preventing common edge blowouts or score lines along the veneer border. By choosing genuine 091066 replacements, operators guarantee exact pocket alignment, balanced aerodynamic performance, and significantly lower machine noise output levels standard to the WhisperCut profile.
