Single-Fluff Twist Router Bit, Pack of 5

【Optimized Chip Removal】The single-flute spiral geometry quickly evacuates chips during deep milling, preventing tool clogging and resin buildup on the cutting edge.
【Mirror-Polished Flute】The polished flute surface reduces friction during cutting, helping to maintain a lower operating temperature and resisting sticking in soft metals and plastics.
【Clean and Precise Cutting Edge】The precision-ground, acute-angle cutting edge initiates clean, burr-free cuts, providing smooth walls in acrylic, wood, and PCB engraving.
【Tungsten Steel】The solid carbide (tungsten steel) construction offers high rigidity with a 3.175 mm shank diameter, minimizing deflection during high-speed CNC engraving.
【Specification 3.175x2x8mm】Shank diameter 3.175 mm, cutting diameter 2 mm, cutting length 8 mm; set of 5 pieces compatible with common hobbyist and industrial CNC spindles and collets.
