CMT Solid Carbide Reversible Insert Knives (4/35 deg.) - 48.3x12x1.5mm - 10-Pack are precision-ground throwaway carbide knives engineered for demanding profiling, molding, and edge-forming operations on spindle moulders, profile machines, and compatible insert cutter head systems. Built from K1920 grade solid carbide and featuring four usable cutting edges at a 35 deg. bevel angle, these indexable insert knives deliver consistent, repeatable cut quality across hardwood, softwood, MDF, chipboard, and plywood - maximizing productivity by allowing operators to rotate to a fresh edge rather than stopping for a full tool change.

Key Features

• K1920 Solid Carbide Material - tungsten carbide grade K1920 provides exceptional hardness and wear resistance, significantly extending service life compared to high-speed steel alternatives when cutting abrasive sheet goods, engineered wood, and dense hardwoods.
• 4 Cutting Edges Per Knife at 35 deg. Bevel - four usable indexable edges per insert means you multiply the working life of each knife, reducing per-edge tooling cost and cutting downtime on production runs.
• Reversible Throwaway Design - when one edge dulls, simply rotate the insert to expose a fresh cutting edge, keeping your cutter head in service longer without sharpening equipment or skilled re-grinding.
• Precision Ground to Exact Dimensions (48.3 x 12 x 1.5mm) - tight dimensional tolerances ensure consistent seating in the cutter head pocket, which translates directly to uniform profile depth and surface finish across every workpiece.
• 10 Knives Per Pack - purchasing in a 10-piece set provides immediate on-hand inventory for index rotations and edge replacements, reducing production interruptions during a job.
• Standard Indexable Knife Format - the HW-K1920 classification is a recognized industry standard format, making these knives compatible with a broad range of insert cutter heads and spindle moulder tooling systems that accept the 48.3x12x1.5mm insert size.

Why This Product

• Four cutting edges per insert means one 10-pack gives you the equivalent cutting capacity of 40 freshly ground knife edges, making this a highly economical choice for shops running high volumes of profiling or molding work.
• The 35 deg. bevel angle and 48.3 x 12 x 1.5mm dimensions match the standard insert specification used by a wide range of cutter heads, so these knives integrate into existing tooling setups without modifications or adapters.
• K1920 carbide grade is optimized for cutting wood-based materials including MDF and chipboard, where abrasive silica content wears softer tooling rapidly - making these inserts a practical upgrade over non-carbide alternatives in composite panel applications.
• The reversible, no-sharpen format removes the need for a tool grinder or grinding service between uses, meaning a small woodworking shop or production floor can maintain cutting performance simply by indexing the insert.
