🚀 DYNAMIC PROPERTIES AND PERFORMANCE:

  • Resistance to Abrasive Materials: the carbide (Vidia) cutting edge, with a hardness of up to 92 HRC, is designed to withstand the abrasive binder and adhesives in MDF, chipboard, HDF, or OSB panels.
  • Z6 High Productivity Configuration: the 6 carbide cutting edges evenly distribute the mechanical load during cutting, ensuring precise groove geometry and constant feed, without shaft vibrations.
  • Silver-Based Brazing: the silver alloy (Ag) used for brazing absorbs micro-shocks from hard laminated materials, preventing cracking or detachment of the inserts.
  • Sustainability and Reuse: the robust special steel body allows, after complete wear of the carbide, professional re-brazing (replacement of worn inserts with new ones) at a specialized center.
  • Flexible Configuration: choose the exact desired groove thickness (4–60 mm) and shaft diameter directly from the variants available on the product page.

⚠️ CRITICAL OPERATING RULES (T.C.T. CARBIDE VERSION):

  • Optimal Application: specifically designed for MDF, chipboard, HDF, laminated wood, hardwoods, and composite materials.
  • Softwood Caution: ❌ on very soft wood (fir, spruce), the tool requires a fast and constant feed!
  • Avoid Overheating: idling with the cutter in direct rotation on resinous woods can cause local burns due to specific friction and the density of the metal carbide.

📊 COMPATIBILITY RATING BY MATERIAL TYPE (T.C.T. CARBIDE)

MDF / Chipboard / HDF / Laminated 100%
Optimal: resistant to abrasive wear of the synthetic binder in these panels.
Hardwood (Beech, Oak, Ash) 100%
Excellent: cutting edge lasts for thousands of linear meters without resharpening.
Composite & Exotic Materials 100%
Maximum: the recommended choice for demanding applications.
Softwood (Fir, Spruce, Pine) Fast Feed Required
Functional, but with risk of burning by friction if the feed is not constant and fast.

💡 For predominant work on softwoods (fir, spruce, pine), where a finish without any risk of burning is desired, the equivalent version with HSS M2 inserts is also available.

🦺 SAFETY MEASURES IN USE:

  • Mandatory protective equipment: safety glasses (against flying chips), mask or respirator filter (fine wood and MDF/chipboard dust), and ear protection for prolonged work.
  • Beware of hands and fingers: maintain a safe distance from the cutting area and use feed/push devices where possible; do not manually intervene near the moving cutter.
  • Maintain a constant feed, especially on soft wood, to avoid the cutter rotating in place on the same spot and the risk of fiber burning.
  • Check the cutter's mounting on the shaft before starting the machine.
  • Observe the recommended speed (6,000 – 9,000 RPM) to avoid vibrations or the risk of damage to the inserts.
