TST Rotary Essentials Bit Kit

The Ultimate Rotary Bit Kit for Metalsmiths

Cut, grind, shape, sand, finish, and polish with confidence—this definitive 80-piece kit has everything you need for your flexible shaft or other rotary tool to bring your small-scale metalwork to life. Experienced metalsmith and educator Kristin Mitsu Shiga sourced this curated collection from a variety of manufacturers so you don’t have to! Included bits were selected to handle both nonferrous metals and steel with ease.

Inside, you’ll find a comprehensive range of Kristin’s most highly recommended bits, covering every step of your process—from cutting & rough shaping to mirror polishing. The collection comes neatly organized in a labeled, partitioned storage box, along with a full reference list detailing each bit and its recommended uses. For added value, the kit also includes a specialty dressing stone to keep your rubberized abrasives performing at their best.

Unlike anything else on the market, this kit saves you from investing over $1000 in full boxes of individual bits. Instead, you’ll get a broad, affordable sample set carefully selected by an expert—perfect for testing, learning, and building your metalsmithing toolkit without breaking the bank.

Whether you’re a beginner exploring rotary tools for the first time or a seasoned metalsmith looking to expand your options, this kit is the most complete and cost-effective collection available.
