Production speed increased by 35% while maintaining top-notch quality.
Why Double Cut Makes a Smoother Finish
Understanding the difference between single and double cut can really boost your project's finish. Think of single cut as a right-handed scraper—it removes material quickly but leaves a bit of texture. Double cut burrs blend right- and left-handed flutes to gently ‘sand’ the surface, resulting in a much smoother finish. Imagine sanding wood first rough, then fine—the double cut burr does the same helping you control the grind without aggressive chipping.
Installation and Maintenance Guide
Setting It Up
- Ensure the shank diameter matches your grinder chuck (1/4" for SJ-1).
- Clean the tool holder before inserting the burr to avoid wobble.
- Insert the burr firmly but do not overtighten to prevent shank damage.
- Check that your rotary tool is set to the recommended speed for carbide burrs (usually 20,000 RPM or less).
- Wear proper safety gear including gloves and eye protection before starting.
Keeping It Going
- Clean burrs after each use to remove debris and extend life.
- Use a wire brush for removing stubborn material build-up.
- Avoid overheating the burr by applying light pressure during use.
- Store in a dry place to prevent rust on tool parts.
- Inspect regularly for wear and replace when cutting edges dull.
