3/8 Inch Shank 1-1/8" Cutting Length Compression CNC Router Bit Spiral End Mill

Designed for clean and efficient machining of wood and wood-based panels, this 3/8" Compression Router Bit combines up-cut and down-cut flute geometry to help minimize chipping and tear-out on both faces of the workpiece. Constructed from K30-grade solid tungsten carbide and finished with a nACo blue coating, the bit provides high hardness, wear resistance, and heat resistance for consistent cutting performance. With a 3/8" cutting diameter, 1-1/8" cutting length, and 3" overall length, it is suitable for deep grooving, slotting, mortising, through-cutting, trimming, and other routing operations on CNC machines, engraving machines, and compatible router tables. Features ✅Up-Cut & Down-Cut Compression Geometry Combines up-cut flutes near the tip with down-cut flutes above them. When the appropriate cutting depth engages both flute sections, this geometry directs cutting forces toward the interior of the workpiece, helping minimize chipping and tear-out on both the top and bottom faces. ✅K30-Grade Solid Tungsten Carbide Manufactured from K30-grade solid tungsten carbide for high hardness, rigidity, and wear resistance, providing stable cutting performance in demanding woodworking and CNC machining applications. ✅nACo Blue Coating Features a nano blue coating designed to enhance surface hardness, heat resistance, and lubricity, helping reduce cutting-edge wear and maintain sharpness during extended machining. ✅Designed for Clean Panel Cutting Compression flute geometry makes the bit particularly suitable for materials where clean edges on both faces are important, including plywood, laminated panels, MDF, and other wood-based sheet materials. ✅Multiple Cutting Applications Suitable for deep grooving, slotting, mortising, through-cutting, trimming, and other routing operations in compatible materials.
