Increased productivity by 30% while cutting down material waste.
Why Double Cut Design Makes a Big Difference
Double cut burrs are like having a twin team working together. With flutes spiraling both right and left, these burrs reduce vibration and chatter, leading to a smoother surface. Think of it like sanding with two sandpapers at once, one taking off the rough stuff, the other polishing it down. This results in better control for you and a much nicer finish on your metalwork.
Installation and Maintenance Guide
Setting It Up
- Make sure the burr fits snugly into your rotary tool chuck or collet.
- Use the correct shank size (1/8") to prevent wobble during use.
- Inspect the burr for any damage before use to ensure safe operation.
- Start at a low speed to get a feel for the burr's action on your material.
- Gradually increase speed as needed while maintaining steady control.
Keeping It Going
- Regularly clean the burr with a wire brush to remove metal buildup.
- Avoid excessive pressure to prevent premature wear or breakage.
- Store in a protective case to keep the cutting edges sharp.
- Replace burrs once cutting efficiency noticeably decreases.
- Wear appropriate safety gear—gloves, eye protection, and mask—during use.
