Combination Spiral Bit (Up/Down Cut Type)

Clean Finish on Both Sides – One Bit Does It All

The Combination Spiral Bit integrates up-cut and down-cut flutes into a single tool, delivering clean and burr-free cutting on both the top and bottom surfaces. Its unique spiral design pulls chips toward the center, reducing edge tear-out and producing high-quality finishes on laminated and veneered materials. Ideal for precision applications where aesthetic quality and dimensional accuracy are critical. Key Features ■High-Quality Finish on Both Sides: Minimizes burrs on both the top and bottom surfaces for a clean, smooth cut ■Efficient Chip Evacuation: Combination up-cut and down-cut flutes direct chips inward for optimal removal ■Precision Cutting: Reduces warping and edge tear-out, delivering improved dimensional accuracy ■Enhanced Productivity: Clean finish eliminates or reduces the need for post-processing ■Ideal for Laminated & Composite Materials: Delivers excellent results on laminated boards, plywood, MDF, and more Specifications ■Applications: • Precision CNC routing 　• Panel machining requiring clean finish on both surfaces 　• Cutouts, drilling, and chamfering on decorative laminated boards 　• Burr and crack prevention in laminated and composite materials ■Work Materials: 　• Wood (plywood, MDF, laminated wood, solid wood, etc.) 　• Plastics (PVC, ABS, acrylic, FRP, resin-formed panels, etc.) 　• HPL (High Pressure Laminate) and multi-layered panel materials ■Compatible Machines: 　• CNC routers 　• Automatic machining centers 　• Dedicated processing machines 　• Handheld trimmers (for small-diameter bits) ■Example Dimensions: 12mm x 12mm x 45mm x 100mm x 2+2P For more details, please refer to the PDF brochure or feel free to contact us.
