Questions about this product
- Will this carbide burr fit a standard 1/4-inch die grinder collet?
- Yes, this burr features a standard 1/4-inch shank that fits most die grinders and rotary tools. It locks securely into standard collets to prevent slipping during heavy-duty deburring. Just ensure your specific tool can reach the high rotational speeds required for carbide.
- What is the maximum speed I can run this rotary file at?
- You can safely run this carbide burr at speeds between 25,000 and 35,000 RPM. Running it faster than this limit can quickly damage the double-cut teeth or snap the shank. Always run the tool in a right-hand rotation to ensure clean chip evacuation.
- Can I use this double-cut burr on hard metals like stainless steel?
- Absolutely, the solid tungsten carbide build features a high hardness rating of 89 to 92 HRA. It easily cuts through tough metals like stainless steel, cast iron, and carbon steel. The double-cut pattern also works well on softer materials like aluminum and wood without clogging.
