1. Made from quality bearing steel: These metal files are crafted from durable bearing steel, known for its extreme hardness. The finegrained texture undergoes a deep quenching process and is coated for maximum longevity, ensuring longlasting cutting performance on a variety of materials. 2. Durable tooth patterns: The gear teeth of each metal file are sharp and clean, delivering enhanced cutting efficiency. Thanks to their clear surface grain, these precision files are incredibly durable, allowing for repeated use without loss of performance. 3. Specialized multipack design: Our file set includes six uniquely shaped tools—flat, round, and halfround (also known as a barrette file). This diversity expands the set's versatility, ensuring you always have the right tool for the job. 4. Versatile applications: This needle file set is for precision work on small surfaces and in tight spaces, ideal for removing, refining, and shaping projects.
