I used it to grind out the hollow part of a spoon and it worked wonderfully. I did 2 spoons from the same maple board. One board I used the Saburr Tooth sphere coarse and the other I used this Kutzall coarse. I thought based on looks that the Saburr Tooth would do the better job, but actually the Kutzall performed better, both in the speed of material removal and ease of handling. I thought the Kutzall would clog with wood and require cleaning every few minutes, but the opposite was true, it never clogged. The Kutzall actually ground out the wood and it came out in a fine dust, while the Saburr Tooth cut out much larger pieces, but at a slower removal rate. The wood heats up with the Kutzall, but it doesn't burn, at least if you keep the tool moving. I also got the fin Kutzall for clean up and it works well too, just not as profoundly as the coarse Kutzall, which is to be expected. I'm glad I got these tools and wish now that I hadn't got the Saburr Tooth tools. I have a dedusting system and work with the project piece with the Foredom rotary tool right at a point of dedusting suction. I generate a lot of the dust and most of it is captured by the dedusting system, but not all, so be sure to wear a dust mask as well. Review: Works great! - This bit handled maple and red oak easily. The barbs got full of sawdust after an hour of use, but it was easily cleaned out with a quick wire brushing. ## Features - Rapid Material Removal: Their hybrid performance removes material at an exceptional rate while maintaining surface quality ready for final finishing. - Easy to Control: The Rotary Burrs can easily cut with or against the grain with incredibly smooth cutting action. The 1/4" diameter shaft burrs are great for larger detail jobs with your die grinder. **Must use with 1/4" collet or adjustable chuck** - Versatile: Easily shape, contour, relieve, notch, flatten, trim, hollow or adjust a wide variety of non-metallic materials including wood, fiberglass, foam, rubber, plastic, drywall, composites and soft-stone. - Incredibly Durable: Featuring Tungsten-Carbide abrasive, 'structured tooth' technology. Outlasts 100X conventional abrasives. Very resistant to loading, they can easily be cleaned with a soft-wire brush or burned with a torch, the heat won't harm the teeth! - Made in the USA: Kutzall Tools have been handcrafted for over 60 years. Their dedication to quality has made them the tools of choice amongst woodworkers and artisans worldwide. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0037MM92K | | Best Sellers Rank | #22,272 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #40 in Cutting Burrs | | Brand Name | Kutzall | | Customer Reviews | 4.5 4.5 out of 5 stars (393) | | Cut Type | Ball End | | Cutting Diameter | 1 Inches | | Cutting Length | 1 Inches | | End Cut Type | Ball End | | Finish Types | Unfinished | | Item Dimensions L x W | 1"L x 1"W | | Item Weight | 1 Ounces | | Manufacturer | Kutzall | | Material Type | Original - Coarse | | Number of Cutting Edges | 6 | | Number of Flutes | 6 | | Shape | Round | | Size Name | Head Diameter: 1", Head Length: 1" | | Tolerance Held | Precision | | UPC | 818050020455 | | Unit Count | 1.0 Count | ## Product Details - **Cutting Diameter:** 1 Inches - **Cutting Length:** 1 Inches - **Finish Type:** Unfinished - **Material:** Original - Coarse - **Number of Flutes:** 6 ## Images ![Kutzall Original Sphere Rotary Burr, 1⁄4" Shaft, Coarse - Wood Carving Bit for Bosch, DeWalt, Milwaukee Tools.

The barbs got full of sawdust after an hour of use, but it was easily cleaned out with a quick wire brushing. ### ⭐⭐⭐⭐ Heavy-duty, but poor finish *by R***D on June 27, 2024* This is described as "coarse", which I think is mildly accurate. I used this kutzall ball to test cut some grooves into walnut drawer face frames - creating a "scalloped" appearance. The cut is very rough - lots of fluff from the tearing action of the cutter. This required me to sand each cut by hand. Instead I used a large, dish-carving bit which gave me a much cleaner finish. I think my intended purpose is somewhat different than what most people buy this for - however, I do think the majority of people should be away of the cut finish being very coarse. I'd equate it to 60 or 80g. The ball is also a heavy rotating mass. I used it in my trim router, but it was really heating up. ## Frequently Bought Together - Kutzall Original Sphere Rotary Burr, 1⁄4" Shaft, Coarse - Woodworking Attachment for Bosch, DeWalt, Milwaukee Tools.
