How the Double Cut Design Improves Finish and Control
The Double Cut feature is like having two cutting actions working together. Think of it as a right- and left-hand spiral flute combo. This setup gives you not only quick material removal but also a super smooth finish because the flutes overlap slightly, creating finer cuts. Plus, the slight left-hand cutting action helps keep the burr steady in your hand and grinder, preventing chattering—a bit like the stability you get when walking with two poles instead of none.
Installation and Maintenance Guide
Setting It Up
- Ensure the grinder or rotary tool is powered off before starting.
- Insert the 1/4 inch shank securely into the collet or chuck.
- Tighten the collet evenly to avoid wobbling during use.

- Use proper protective eyewear and gloves when operating.
Keeping It Going
- Clean the burr after use to remove metal or wood debris.
- Store in a dry place to prevent any corrosion or damage.
