MDF-Grade solid carbide insert knives included. Optional general purpose knives available.
Insert spoilboard surfacing & rabbeting with scorers features unique 2+2 knife design that contains two cutting flutes and two up-shear scorers, which provide a smoother finish at the bottom of the cut than traditional two-knife style router bits. Engineered with an Amana-exclusive carbide grade for the highest quality of cut, maximum cutting efficiency, and faster material removal process. Also known as a Surface Planing, Rabbeting, Flycutter, Fly Cutter, Leveler and Bed Skimming Router Bit. Read a woodworker's review of these bits and Read "Natural Art", a blog on slabbing camphor laurel wood.
Perfect for:
- Resurfacing spoilboards using CNC
- 2 + 2 spoilboards contain 2 bottom scorers for better performance, finer surface finish and better clearance for 90° corners
- Planing large glued up panels using CNC
- Surfacing and finishing wood using timber slab machines
- Rabbeting or slotting
These industrial router bits comes complete with four (4) MDF-Grade solid carbide insert knives, each with four (4) cutting edges that allow users to rotate the knife when one side becomes dull. Designed for spoilboarding, planing & rabbeting large surface areas in the following materials:
- MDF
- Fiberboard
- HDF/LDF
- High Density Urethane (HDU Board)
- Balsa Core*
- Plastic/Acrylic**
- Solidwood/Softwood*
- Plywood/Chipboard*
- Ultra-High-Molecular-Weight Polyethylene (UHMWPE)
*For optimal results and maximum insert life, replace inserts with optional general purpose knives #AMA-12 and #RCK-70 (sold separately).
**Use lower CNC spindle RPM and adjusted feed-rate to prevent Melting and adhesion of the acrylic material to the tool.
Max RPM #RC-2251 = 19,000
Max RPM #RC-2252 = 18,000
Max RPM #RC-2351 = 19,000
RC-2251 and RC-2253: Also suitable for router sled machines, Make sure that your router sled is fully stable and squared.
The RC-2252 industrial router bit used in conjunction with the Amana Tool® Straight Plunge 45200 to square out the corners make production of MDF Shaker-style doors economical and less labor-intensive, while producing superior results.
Recommendations: For surfacing solid woods it is recommended to remove both bottom scorers.
