## Description

Kutzall burrs are the perfect companions for your rotary carving tools, designed to work easily and efficiently where other conventional tools fail. Proudly crafted in the USA, they perform with remarkable wear-life and provide a truly unique combination of superior material removal and surface quality. With effortless operation (with or against the grain) and resistance to loading, you'll use them project after project. Their outstanding performance on a wide variety of materials will keep them locked in your favorite grinder. Wood, plastic, drywall, rubber, fiberglass, and soft stone, they will be your go-to workhorse for any task. NOTE: Should only be used on non-metallic materials. Sphere - The Sphere Burr is the perfect option for when you need to hollow out a concave surface, or produce a radius. Need to produce an undercut or overhung edges? This burr is the easy choice. Extreme Coating – When heavy material removal is desired. Exceptionally resistant to loading; great for working with wet or gummy woods. Diameter and head length dimensions on Kutzall burrs are base dimensions. The coatings add approximately .060" - .102" Compatible with popular grinders with 1/8” collets or adjustable chucks including: Dremel, Foredom, Dewalt, Milwaukee and more. Recommended operating speed range is 10,000 - 25,000 RPM. They will remove material at lower speeds (hand drills, drill presses) but both material-removal rate and control improve as speed increases. Cleaning: They can be easily cleaned using a torch and/or a quick few passes with a soft wire brush, the heat will not harm the teeth!

Review: I now have a good set of Kutzall bits for my wood carving. They all work great and I would buy them again.
Review: These are great carving burrs. I have the next size up in course and fine, they worked so well I got this smaller size for more detailed work. Happy with them so far, the course round burr really does a good job of quickly removing material, just know you will very likely be left with lines in your work. So recommend having the fine grit as well.
