Precision CNC engraving bits designed for accurate, clean cuts and long service life. Key benefits Cleaner cuts and less clogging: Optimized flutes channel wood chips away from the cutting edge to keep the bit cutting efficiently and prevent chips from affecting your work. Fast, smooth cutting: High cutting speed produces flat, smooth surfaces that reduce finishing time. Durable, high-hardness material: Made of wear-resistant tungsten steel with high hardness — sharper and less fragile than ordinary carbide CNC drills for extended tool life and consistent performance. Ready-to-use set: Four individually wrapped bits in one pack so you have the right tip for multiple tasks and easy storage. What’s included (single package) 4 pieces per pack, each individually wrapped 1 x 15° detail drill 1 x 20° profile drill bit 1 x 60° V-groove drill 1 x 90° V-groove drill Function and compatibility Purpose-built for CNC engraving and routing tasks that require precision profiles, V-grooves, and fine detail work. Suitable for use where chip evacuation, surface finish, and tool life matter. Performance and materials Tungsten steel construction provides high hardness and wear resistance while remaining less prone to breakage than ordinary carbide bits. Scientifically designed flute geometry improves chip removal and helps maintain cutting speed and surface quality. Practical applications Fine detail carving: 15° detail bit for delicate lines, inlays, and intricate relief work on hardwoods and softwoods. Edge profiling and shaping: 20° profile bit for clean profile cuts, small chamfers, and decorative edges. Lettering, V-grooves, and signmaking: 60° and 90° V-groove bits for crisp lettering, chamfers, and groove details in signs, panels, and moldings. Why choose this set A compact, versatile selection of bits for common engraving and routing needs. Individually wrapped pieces protect each bit and make it easy to rotate or replace tools during a job. Designed to reduce chip-related interruptions and deliver consistent, smooth cuts across a range of projects.
