Cedar Rapids, Iowa – Upgrading to SM-61 to improve metal finishing speed and quality.
"Since switching to the SM-61 double cut burr, our metal finishing has become noticeably smoother and faster. The control it offers makes complex jobs easier."

Production efficiency increased by 35%, with less rework required on metal surfaces.
How the Double Cut Flute Design Enhances Your Metalworking
The Double Cut version of the SM-61 combines right and left hand spiral flutes to create a smoother, more controlled cutting action. Think of it like holding a finely tuned paintbrush instead of a rough-edged roller—it allows you to gently shape metal surfaces while avoiding roughness or unwanted scratches. This design offers a slight left hand cutting motion that helps in preventing the burr or grinder from slipping, giving you better control and a polished finish every time.
Installation and Maintenance Guide
Setting It Up
- Ensure your rotary tool is off before inserting the burr for safety.
- Check that the 1/8" shank fits securely in your tool's collet or chuck.
- Tighten the chuck firmly to avoid vibration during use.
- Choose Single or Double Cut based on your material and finish requirements.
- Wear appropriate personal protective equipment like goggles and gloves.
Keeping It Going
- Clean the burr regularly with a wire brush to remove debris and resin buildup.
- Avoid excessive pressure while cutting to preserve the sharpness of the flutes.
- Store your burrs in a protective case to prevent damage when not in use.
- Inspect for any signs of wear or chipping before each use.
- Use proper cutting speeds recommended for your material to extend burr life.
