Case Study: Real Business, Real Results
Located in Houston, TX, Precision Metalworks needed to upgrade their burr tools to improve finish quality on mixed metal parts.
"Switching to the SL-7 burr gave us smoother finishes and better control, drastically reducing rework time across several projects."

Boosted quality output by 30% while cutting finishing time nearly in half.
How the Double Cut Design Gives You Superior Finish and Control
Double cut carbide burrs feature both right and left hand spiral flutes, working together like a dance duo to finely shave away material. Imagine sanding wood not with rough sandpaper but with a perfect blend of grains—this balanced cutting action smooths surfaces better while giving you excellent handling and control over the tool. In contrast, a single cut is faster but can leave rougher textures. So when your job needs that salon-smooth finish, the double cut option is your go-to.
