Leitz Premium HW Scraper Insert 12x20x2 R=1 Anti-Bleaching L74095
HW Scraper Anti-Bleaching
Insert CHANGE-ME
Precision tungsten-carbide profile scraper insert engineered to reduce whitening and friction stress during polymer-edge finishing. Its 12 × 20 × 2 mm format, R=1.0 mm radius, and anti-bleaching micro-form geometry support clean finishing on ABS, PVC, and other edgebanding materials.
Main Product Description
The Leitz HW Anti-Bleaching Scraper Insert CHANGE-ME L74095 is developed for industrial edgebanding machines processing ABS, PVC, and other polymer edge materials. Its 12 mm width, 20 mm length, 2.0 mm thickness, and R=1.0 mm profile provide a defined mounting envelope and repeatable finishing geometry.
Sub-micron HW carbide provides resistance to abrasive wear during continuous production. The anti-bleaching micro-form relief is designed to reduce localized pressure and friction that can cause visible whitening along plastic edge radii, while the mirror-honed face supports smooth chip flow and reduced adhesive buildup.
Optimized axial-shear relief parameters help the insert remove the fine ridge left after radius milling without adding chatter marks or excessive surface stress. Correct aggregate alignment, clamping torque, and radius setup are essential for consistent cosmetic finish and reliable service life.
Best Fit Applications
Product Highlights
Anti-Bleaching Geometry
Micro-form relief helps reduce localized pressure and visible whitening on dense polymer edgebanding materials.
Sub-Micron HW Carbide
Premium tungsten carbide supports wear resistance and dimensional stability during repeated automated scraping cycles.
Mirror-Honed Finish
The polished face supports smooth chip removal and helps reduce hot-melt adhesive buildup and friction streaking.
Compatibility & Installation Notes
Power down and isolate the edgebanding line before replacing the insert CHANGE-ME. Confirm that the scraper aggregate accepts the 12 × 20 × 2 mm format and that the R=1.0 mm profile matches the upstream radius-milling setup. Verify alignment with precision indicators, tighten clamping screws to the specified torque, and avoid direct metal impact on the carbide edge during handling.
Improve Polymer Edge Finish Quality
The Leitz HW Anti-Bleaching Scraper Insert CHANGE-ME L74095 is specified for premium cabinetry, panel processing, and high-throughput edgebanding lines requiring controlled radius finishing. Its 12 × 20 × 2 mm format and R=1.0 mm profile support repeatable installation and accurate edge geometry.
Sub-micron carbide, anti-stress relief geometry, and a mirror-honed face help reduce whitening, adhesive buildup, chatter marks, and manual touch-up requirements across continuous ABS and PVC edge-finishing operations.
