Compatible with major grinders like Bosch and DeWalt, it offers exceptional durability—outlasting conventional abrasives by 100x—and smooth cutting action for detailed shaping, trimming, and carving. Made in the USA with over 60 years of craftsmanship, it’s the go-to tool for professionals demanding speed, control, and longevity.

## 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. Flame - The unique shape of the Kutzall Flame Burr is designed to shine in a variety of detail- cutting scenarios. The Flame Burr is used to produce soft concave cuts, or notch V's with a gentle radius. The "pencil" tip on the Flame Burr is also great for handling any of your detailed carving tasks. 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 .090" - .164" Compatible with popular grinders with 1/4” collets or adjustable chucks including: Bosch, Dewalt, Foredom, 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: Come mi aspettavo ,fa quello che deve. Anche sforzando un po' non ha punti deboli, il gambo da 6 mm regge bene. Lascia il lavoro un po'grezzo. Contento.
Review: Vu la réputation de la marque, je m'attendais à plus impressionnant... Ça reste une très bonne fraise qui enlève pas mal de matière mais montre ses limites sur du bois dur. J'ai des doutes sur l'encrassement, je verrai a plus long terme.

## Questions & Answers

**Q: What type of tool to you put this into a router, a drill, seems too much for a dremel, even if you could find a collette?**
A: The 1/4" shaft Rotary Burrs, are meant for Die Grinders, or Flex-Shaft hand pieces with a 1/4" collet or adjustable chuck.

**Q: What tools accept this shaft**
A: drill press, hand drill, router, air grinder with 1/4 inch collet.

**Q: Is there an adapter that will allow this to be used in the Dremel 4250?**
A: Sorry Tommy, this is a 1/4" shaft and the biggest burr that the Dremel will take is 1/8".  If you have already bought this burr send it back to Amazon and replace it with an 1/8" shaft. Kutzall make the flame in extra coarse 1/8" but be extra careful. This thing will rip through your fingers very quickly. Make sure you have no clothing to get caught up or around your carving area. It will grab the material and snap your shaft. Don't drop it in your lap because you will find it quite painful. Good luck.

**Q: Can it be used with a drill instead of a  die grinder?**
A: For DIY applications, Kutzall Burrs will remove material at lower speeds (hand drills, drill presses, etc.) but both material-removal rate and control improve as speed increases. Recommended operating speed range is 10,000 - 25,000 RPM.
