Diamond Grinding Bit Set 20Pcs 120 Grit 1/8″ Shank by Nakonic Burrs

Description

Product Overview

The Nakonic 20‑piece diamond grinding bit set is engineered for professionals and hobbyists who demand precision and durability in their rotary tooling. Each bit features a fine 120 grit diamond coating that provides a smooth, consistent finish on a wide range of hard materials, including glass, stone, resin, and porcelain. The 1/8 inch shank is a universal size that fits directly into Dremel, Hardell, Milwaukee, DeWALT, and other compatible rotary tools without the need for adapters. Constructed from high‑grade industrial steel, the bits maintain structural integrity even under prolonged use, while the diamond particles are bonded using a proprietary process that resists shedding and impact damage. The set includes six distinct head shapes—cone, ball, cylinder, dome, flat, and tapered—allowing users to tackle carving, engraving, polishing, deburring, cutting, drilling, and milling tasks with a single kit. Package dimensions of 4.76 x 4.13 x 0.79 inches and a lightweight 3.2‑ounce total weight make storage and transport effortless, while the included detailed specifications ensure you have all the information needed for optimal performance.

Usage

This diamond grinding bit set excels in both workshop and field environments. Whether you are restoring antique glassware, sculpting intricate stone designs, or performing precision polishing on resin components, the bits deliver reliable results. The fine 120 grit is ideal for achieving a high‑gloss finish on delicate surfaces, while the robust shank ensures stable rotation at high speeds. For best outcomes, operate the bits at moderate RPMs, apply light, even pressure, and employ water cooling or a misting system to reduce heat buildup and prolong the life of the diamond coating. The set is also suitable for educational settings, where students can explore material science and fine‑detail craftsmanship under supervised conditions. Its compatibility with multiple leading rotary tool brands means you can integrate the set into existing tool collections without additional investment.
