Type B1 Geometry
Identified for the Type B1 position in the applicable WhisperCut exchangeable-knife arrangement.


A precision-matched DP/PCD spare knife for compatible Leitz WhisperCut jointing cutter systems. The SB6.7 Type B1 configuration provides the specified geometry required for its assigned position within the cutterhead’s exchangeable-knife arrangement.
This exchangeable knife belongs to the Leitz WhisperCut spare-knife program for panel-edge jointing systems. It is identified by the SB6.7 designation, Type B1 geometry, DP cutting material, and the exact 6.7 × 14.2 × 4.3 mm size.
Correct matching is essential: verify the cutterhead’s documented knife type, arrangement, and seating position before replacement.
The Leitz WhisperCut SB6.7 Type B1 is an exchangeable spare knife used within compatible WhisperCut jointing and milling cutter systems for panel-edge processing. Its geometry and dimensions are specific to the Type B1 position in the applicable cutterhead configuration.
Leitz identifies this component as an eroded DP spare knife designed for quick and straightforward knife replacement. The 6.7 × 14.2 × 4.3 mm dimensions and Type B1 profile must be matched exactly rather than substituted solely by general size or cutting-material description.
Within a correctly configured WhisperCut cutterhead, this component supports jointing applications on edgebanding and related panel-processing equipment. The complete cutter system is intended for machining raw, veneered, painted, and coated chipboard or fibreboard surfaces, including decorative papers, foils, HPL, and anti-fingerprint finishes.
Technical Specifications
Identified for the Type B1 position in the applicable WhisperCut exchangeable-knife arrangement.
Uses polycrystalline diamond cutting material as specified in the Leitz spare-knife catalogue.
Part of Leitz’s eroded spare-knife system for direct replacement in a correctly matched cutterhead.
Confirm that the existing Leitz WhisperCut cutterhead specifically requires the SB6.7 Type B1 knife with 6.7 × 14.2 × 4.3 mm dimensions and the matching catalog shape position. Verify the cutterhead model, knife arrangement, seating face, clamping components, rotation, allowable operating speed, machine guarding, and manufacturer service instructions. Do not substitute a B2, A1, A2, C1, C2, D1, D2, or full-width SB14 knife based only on similar dimensions or appearance.
Maintain the specified knife configuration of a compatible Leitz WhisperCut jointing cutterhead with the correctly matched SB6.7 Type B1 exchangeable knife. Measuring 6.7 × 14.2 × 4.3 mm and manufactured with DP/PCD cutting material, this component is intended for the designated Type B1 position within applicable WhisperCut panel-edge processing systems. Always match the knife by its complete designation, dimensions, geometry, and cutterhead documentation before replacement.
Use only where the documented Leitz WhisperCut cutterhead specifies the SB6.7 Type B1 geometry, dimensions, and DP/PCD cutting material.
