Set of 10 V-Engraving Cutters, 60° Mirror Edge, 3.175mm Shank

【Tungsten Steel Core】This drill bit is machined from a single piece of tungsten steel, allowing it to resist bending and breakage under lateral loads, protecting your workpiece during aggressive engraving on metal or hardwood.
【Mirror Polished Cutting Edge】The precision-polished, 60-degree V-edge with a 0.3mm tip provides a burr-free surface finish right out of the machine, eliminating the need for secondary sanding on fine details.
【Oversized Spiral Geometry】Designed with a wide chip gullet, this geometry quickly removes micro-debris from the cutting area, preventing heat buildup and clogging for cleaner, uninterrupted engraving passes.
【0.3mm Precision Tip】The sharp 0.3mm tip delivers crisp lines and Fine in the fabrication of complex signs, PCB trace insulation, and detailed 3D relief mapping, maintaining tight tolerances with every pass.
【Uniform Set of 10 Pieces】Supplied in a pack of ten identical 3.175 mm shank drill bits, this set ensures consistent performance on multiple CNC milling machines, ideal for production runs and testing various materials.
