Whether you are producing cabinet door profiles, decorative molding, or edge treatments, these insert shaper knives bring accuracy and repeatability to every pass.
Key Features
- Alloyed Steel Construction - made of alloyed steel for durability and long-lasting performance, meaning fewer replacements and consistent results over extended use cycles.
- 40x4mm Knife Size (1-37/64 in. x 5/32 in.) - precise dimensional sizing ensures a secure, accurate fit in compatible universal cutter heads, producing repeatable profile geometry on every workpiece.
- Universal Cutter Head Compatibility - designed for use with CMT universal insert shaper cutter heads, giving you the flexibility to run a wide variety of molding profiles without investing in multiple dedicated heads.
- Sold as a Pair (2 Knives) - each purchase includes 2 matched profile knives, providing a balanced cutting configuration required for safe and smooth shaper operation.
- Variety of Profile Options Available - part of a broad range of CMT insert shaper profile knives, so you can build a complete set of profiles around a single cutter head system, reducing overall tooling costs.
Why This Product
- For woodworkers who need versatility without bulk, these knives integrate into the CMT universal cutter head system - meaning one set of heads can accept a wide range of profile knives rather than requiring dedicated tooling for every shape.
- The alloyed steel material provides long-lasting performance, making these knives a practical choice for production environments or frequent-use shops where tool life directly affects output quality and cost.
- At 40x4mm (1-37/64 in. x 5/32 in.), the knife dimensions are precisely sized for a secure fit, reducing the risk of chatter or profile inconsistency during molding and profiling operations.
- Purchasing a matched pair ensures balanced cutting forces at the shaper spindle - an important safety and quality factor when running insert-style cutter heads on a spindle moulder or profile machine.
