CMT Solid Carbide Insert Knives (4/35 deg.) 12x12x1.5mm - 10-Pack by CMT are precision-ground, reversible carbide cutting inserts engineered for spindle moulders, profile machines, edging machines, and router tables equipped with compatible insert cutter heads. Built from K1920 solid carbide with a 35 deg. bevel angle and four usable cutting edges per knife, these square insert knives deliver consistent, repeatable performance across hardwood, softwood, MDF, chipboard, and plywood - keeping your machine running longer between tool changes and reducing per-edge tooling cost.

Key Features

• K1920 Solid Carbide Material - tungsten carbide grade construction provides exceptional wear resistance, meaning more cuts between edge rotations compared to standard high-speed steel inserts, especially in abrasive materials like MDF and chipboard.
• Four Reversible Cutting Edges per Knife - with four usable edges on each square insert, you quadruple the service life of every knife before replacement is needed, lowering tooling cost per linear foot of profile.
• 35 deg. Bevel Angle Geometry - the 4/35 deg. grind produces a controlled, efficient shear cut that reduces tear-out on hardwood and softwood edges, yielding cleaner profiles with less sanding required.
• 12x12x1.5mm Precision Dimensions - each knife is ground to exact 12mm length, 12mm cutting depth, and 1.5mm thickness tolerances, ensuring consistent seating in compatible insert cutter heads and uniform profile results across the full pack.
• 0.75mm Corner Radius - the built-in radius on each cutting corner softens transitions in profiles and helps prevent chipping at the knife tip during aggressive cutting passes.
• 10 Knives per Pack - stocking a full 10-piece pack means you have replacement edges on hand to maintain production continuity without waiting for a reorder.
• Compatible with CMT 692 Series Cutter Heads and Insert Shaper Systems - direct-fit design for CMT's established 692 series platform and compatible insert shaper systems means no modification or shimming required for installation.

Why This Product

• With four indexed cutting edges per knife and a 10-piece pack, you get 40 total cutting edges - providing extended production capability without frequent tool changes on spindle moulders and profile machines.
• The K1920 solid carbide grade is well-suited for abrasive engineered wood products like MDF and chipboard, where softer tool materials wear rapidly - making these inserts a practical choice for shops working across multiple material types.
• The 35 deg. bevel geometry supports profiling, rabbeting, grooving, and jointing operations in a single reversible knife platform, reducing the number of different insert types needed in inventory.
• Precision-ground 12x12x1.5mm dimensions ensure each edge seats consistently in the cutter head, so profiles remain accurate from the first edge through the last - critical for matched joinery and molding work.
