Product Description
CMT Solid Carbide Replaceable Knife - 4/35 deg. - 36x12x1.5mm HW-SMG - 10-Piece Pack delivers precision insert knife performance for CNC router heads and spindle moulders handling hardwood, softwood, plywood, and MDF. Engineered from N2550 solid carbide and ground to a 35 deg. bevel angle with a 4-tooth configuration, these reversible insert knives are built for high-volume production environments where consistent edge quality and long tool life are essential. Each pack includes 10 replacement knives, making it easy to maintain uptime on machining centers, point-to-point machines, and CNC routing equipment without extended downtime waiting for individual replacements.
Key Features
- N2550 Solid Carbide Material - provides maximum wear resistance during long production runs, maintaining cutting edge integrity far longer than standard high-speed steel alternatives in demanding routing applications.
- 4/35 deg. Grind Angle - the 35 deg. bevel geometry is optimized for clean, precise cuts across a range of engineered and natural wood products, reducing tear-out and producing smoother finished surfaces.
- 36x12x1.5mm Knife Dimensions - the exact profile ensures a drop-in fit for compatible CNC router heads and spindle moulder bodies that accept this insert knife standard, eliminating adjustment time during changeovers.
- 4-Cutting-Edge Configuration - with 4 usable cutting edges per knife, each insert delivers multiple service intervals before replacement, lowering the per-edge tooling cost over a production run.
- HW-SMG Replaceable Insert Design - knives are individually replaceable without removing the entire cutter head, reducing machine downtime and simplifying routine maintenance for production shops.
- 10-Piece Pack Quantity - stocking 10 knives per pack keeps a ready supply on hand for continuous production, minimizing interruptions when a knife edge reaches the end of its service life.
- 1.5mm Knife Thickness - the precise 1.5mm thickness (0.059 in.) maintains tight tolerances within the cutter body seat, supporting stable, chatter-free cutting performance at production feed rates.
Why This Product
- The N2550 solid carbide construction is specifically suited for production-volume CNC routing and spindle moulding, where insert knives face repeated impact and abrasion from hardwood, plywood, and MDF - materials that rapidly dull less wear-resistant tooling.
- The 4-edge design means each individual knife stretches your tooling investment across multiple cutting sessions - when one edge dulls, simply index to the next rather than swapping the insert immediately, keeping your machine running longer between changeovers.
- At 36mm total length and 12mm cutting depth, this insert knife fits CNC router and machining center cutter bodies that require this specific HW-SMG standard profile, making it a reliable like-for-like replacement with no modification needed.
- Buying in a 10-piece pack ensures you always have replacement knives on hand for multi-shift production environments, reducing the risk of unplanned downtime caused by running out of insert tooling mid-run.

Frequently Asked Questions
How many cutting edges does each knife in this pack provide?
Each knife features 4 cutting edges, as indicated by the 4-tooth specification. This means each insert can be indexed to a fresh edge multiple times before the knife needs to be replaced, extending the usable life of every piece in the pack.
What material are these replacement insert knives made from?
These knives are manufactured from N2550 solid carbide, a material selected for its high wear resistance and durability in continuous wood machining operations including routing of hardwood, softwood, plywood, and MDF.
What does the 4/35 deg. designation mean for these knives?
The designation refers to the knife's 4-tooth configuration combined with a 35 deg. bevel grind angle. The 35 deg. angle defines the cutting geometry and influences how cleanly the knife shears through wood fibers during CNC routing or spindle moulding operations.
What is the knife thickness and why does it matter for installation?
Each knife has a thickness of 0.059 in. (1.5mm). This precise dimension is critical for proper seating within the cutter body - the correct thickness ensures the knife sits flush and stable in the insert pocket, which directly affects cutting accuracy and reduces vibration during operation.
