Leitz Premium HW Scraper Blade 12x20x2mm R=2 Anti-Bleaching
HW Scraper Anti-Bleaching
Insert Blade
High-precision tungsten-carbide scraper insert engineered for industrial edgebander profile-finishing units. Its 12 × 20 × 2 mm format, R=2.0 mm radius, and anti-bleaching micro-geometry support smooth polymer-edge finishing while reducing stress whitening on ABS, PVC, PMMA, and thick plastic edgebands.
Main Product Description
The Leitz HW Anti-Bleaching Scraper Insert Blade L74098 is designed for industrial edgebanding lines requiring accurate radius finishing on plastic and polymer edge materials. Its 12 mm width, 20 mm length, 2.0 mm thickness, and R=2.0 mm profile provide a defined mounting envelope for compatible scraper blocks.
Premium-grade tungsten carbide supports wear resistance during continuous contact with ABS, PVC, PMMA, and thick plastic edgebands. The anti-bleaching micro-geometry helps control localized pressure and material stress that can cause visible whitening along dark or high-gloss edge profiles.
Precision-ground clearance angles and a mirror-finished working surface support smooth chip removal, reduced vibration marking, and consistent radial continuity. Correct scraper-block cleanliness, alignment, trace pressure, and clamping torque are essential for dependable finish quality and service life.
Best Fit Applications
Product Highlights
Anti-Bleaching Geometry
Specialized relief and clearance angles help reduce material stress and visible whitening on dark polymer edgebands.
Premium Tungsten Carbide
Solid-carbide construction supports wear resistance and stable edge geometry during repeated automated scraping cycles.
Consistent R=2 Profile
Precision grinding supports continuous radial geometry and smooth chip extraction across compatible finishing aggregates.
Compatibility & Installation Notes
Power down and isolate the edgebanding line before installation. Confirm that the scraper block accepts the 12 × 20 × 2 mm format and that the R=2.0 mm profile matches the upstream radius-processing setup. Clean all resin and adhesive residue from the mounting pocket, tighten the clamping hardware to the specified torque, and run test panels to calibrate trace pressure and copy-wheel settings.
Improve Polymer Edge Finish Quality
The Leitz HW Anti-Bleaching Scraper Insert Blade L74098 is designed for cabinet, panel, and millwork manufacturers requiring repeatable radius finishing on demanding polymer edgebands. Its 12 × 20 × 2 mm format and R=2.0 mm profile support accurate installation and controlled finishing on compatible industrial equipment.
Tungsten-carbide construction, anti-bleaching micro-geometry, and precision-ground surfaces help reduce whitening, chatter marks, adhesive buildup, and manual rework while supporting consistent production-line output.
