Tungsten Carbide Burr 1/8 Inch SHARPRO Cutting Tool Ultra‑High Speed

Description

Product Overview

The SHARPRO Tungsten Carbide Burr 1/8 Inch is a precision‑engineered cutting accessory designed for demanding industrial and hobbyist applications. Constructed from premium AG10F bar stock, the burr incorporates a high cobalt content (10%) that significantly boosts wear resistance compared with standard YG‑6 grades. Its 170° angle tip is optimized for aggressive material penetration while maintaining a smooth surface finish, reducing the need for secondary deburring operations.

Measuring just 1/8 inch in diameter, the burr delivers a compact footprint that fits a wide range of rotary tools, including Dremel, Proxxon, and other high‑speed hand‑held devices. The design tolerances keep surface roughness below Ra 0.8 µm, ensuring clean cuts and minimizing heat buildup during prolonged use. The burr is non‑welded, meaning the grinding particles are integrally formed for added durability and reduced chip breakage.

Key specifications include a recommended operating speed of 18,000–25,000 RPM, making it suitable for both plunge milling and surface grinding. The package dimensions (7.01 × 4.8 × 0.51 in) and lightweight construction (0.35 oz) provide easy handling and storage. The product carries the model number SPWSST3.22 and is tracked with a unique serial code for full traceability throughout the manufacturing process.

Designed for versatility, this burr excels on a variety of substrates such as cast iron, hardwoods, plywood, MDF, and plexiglass. It is not recommended for aluminum due to its specific material composition. The combination of high cobalt content, precise geometry, and robust construction makes it a reliable choice for professionals seeking consistent performance across multiple material types.

Usage

When employed in woodworking projects, the SHARPRO burr quickly removes excess material, allowing craftsmen to shape intricate details, create decorative inlays, and perform fine carving work. Its high‑speed capability ensures that even dense hardwoods are cut with minimal effort, reducing operator fatigue during extended sessions.

In metalworking environments, the burr’s carbide composition enables efficient grinding of steel components with hardness ratings between HB125‑400. The 170° tip penetrates surface layers cleanly, making it ideal for preparing weld joints, removing rust, and smoothing rough edges on cast iron or steel parts.

For plastics such as plexiglass and acrylic, the burr provides a clean, burr‑free finish, essential for optical applications where surface clarity is paramount. The low heat generation at recommended RPMs prevents melting or warping of thermoplastic materials.

Installation is straightforward: simply insert the burr into the collet of a compatible rotary tool, tighten according to the tool’s specifications, and set the appropriate speed. Safety precautions include wearing eye protection, securing workpieces, and ensuring the tool is powered off before changing accessories.
