Flat Nose 3 Flute Spiral Roughing Bit for MDF and Compression Materials

A heavy-duty CNC roughing bit designed for fast and efficient machining of MDF, plywood, and wood-based composite materials. Featuring a 3-flute spiral roughing design with wave-shaped chip breaker grooves, it delivers aggressive material removal, efficient chip evacuation, and extended tool life for demanding woodworking applications.

Key Features

• 3 Flute Roughing Spiral Design
  Optimized for deep and fast material removal with improved machining efficiency.
• Wave-Shaped Chip Breaker Grooves
  Serrated waveform teeth improve chip evacuation and reduce tool clogging during heavy cutting.
• Up-Cut Spiral Geometry
  Enhances chip flow and improves surface finish on the bottom side of the workpiece.
• High-Quality Solid Carbide Construction
  Made from premium micro-grain tungsten steel solid carbide for excellent hardness, wear resistance, and long service life.
• Sharp Precision Cutting Edge
  Precision-ground cutting edges provide smooth cutting performance with minimal burr formation.
• Multi-Purpose Machining Capability
  Suitable for cutting, engraving, bottom cleaning, slotting, trimming, and rough machining operations.
