Durability and Performance You Can Rely On
The SL-3 L6 Extended Shank Double Cut Carbide Burr isn’t just about precision; it’s built to last throughout your toughest jobs. Crafted from premium tungsten carbide, this burr tolerates high heat and abrasive wear better than many competitive tools. This means less downtime replacing dull tools and more productivity—keeping your operation running smoothly day after day. Its extended shank not only opens up access to hard-to-reach areas but also maintains rigidity so you experience minimal vibration and greater control.

Case Study: Real Business, Real Results
Located in Cleveland, Ohio, Precision Metalworks switched to the SL-3 L6 Extended Shank Double Cut Burr to improve their finishing process on custom automotive parts.
“The extended reach and smooth cutting action gave us better control and much finer finishes, shaving hours off our post-production time.”
Jenna Marshall – Lead Fabricator
Production efficiency increased by 35% while maintaining consistent surface quality.
How Double Cut Design Enhances Your Finish
Double cut burrs use two sets of cutting flutes: one spirals to the right, the other to the left. Imagine walking a tightrope with both arms balancing—you get much better control and smoother movement. Likewise, this double action results in finer chips and less vibration, giving you a cleaner, smoother surface. It’s like smoothing rough wood with two brushes instead of one, leaving behind a professional-grade finish every time.
Installation and Maintenance Guide
Setting It Up
- Ensure the grinder or rotary tool is switched off before installing the burr.
- Clean the collet or chuck to remove debris for secure fitting.
- Insert the 1/4" shank fully into the collet and tighten firmly but not over-tightened.
- Wear safety goggles and gloves before operation for protection.
- Start with a low speed to test the fit and stability.
Keeping It Going
- Regularly check the burr for wear or damage; replace if cutting edges dull.
- Clean burrs after use with a brass wire brush to remove built-up material.
- Avoid excessive pressure to prolong burr life and maintain finish quality.
- Store burrs in a dry, safe place to prevent corrosion or damage.
- Use the appropriate cut type for your material for best performance and longevity.
