What you get 10-piece set of carbide end mill engraving bits Each bit has a 7 mm cutting diameter and a 0.12 inch shank Why this set solves problems for you Precision cutting: 7 mm diameter delivers consistent, accurate grooves and profiles so finished parts meet your tolerances. Durable material: carbide construction resists wear and holds an edge longer than high-speed steel, reducing downtime and replacement costs. Cleaner results: geometry optimized for minimal burrs and smoother edges, lowering post-processing time and improving part quality. Broad compatibility: the 0.12 inch shank fits tools and collets that accept that common size, making the bits easy to integrate into existing setups. Key benefits at a glance Reliable performance across multiple materials Reduced tool wear and longer service life Improved finish quality with fewer touch-ups Convenient 10-piece pack for repeat jobs or multiple machines Typical applications (practical use cases) 1. Electronics prototyping: engraving circuit boards and trimming pads for quick PCB revisions and small runs. 2. Metal and jewelry work: precise milling and detail cuts on softer metals for custom components and small decorative pieces. 3. Wood, plastics and modelmaking: routing fine details, lettering, and inlays with consistent edge quality. Suitability and performance Material: carbide for high stiffness, heat resistance, and long-lasting edges Size: 7 mm cutting diameter for medium-detail work; 0.12 inch shank for standard small-tool collets Performance: designed for efficient, precise material removal with reduced burr formation and minimized tool wear This 10-piece carbide set is practical for hobbyists, prototypers, and light production environments where repeatable, clean cutting on a variety of materials is required.
