Case Study: Real Business, Real Results
Located in Milwaukee, Wisconsin, Precision Metalworks upgraded to the SF-13 for smoother finishes and quicker turnaround times.
"Switching to the SF-13 carbide burr dramatically improved our workflow. The double cut option gives us unbeatable finish quality, and it’s tough on all the different metals we use."
David L. Morrison – Lead Machinist
Resulted in a 35% increase in daily output and reduced rework on finished parts.
How Double Cut Turns Rough Work Into Smooth Masterpieces
The double cut burr in the SF-13 combines right and left hand flutes, which is like having two tools working in harmony. Imagine sanding a wooden chair with two different grits at once — it both removes material efficiently and leaves a sleek finish. This combo reduces vibration and gives you better control, so you’re less likely to gouge or overcut your workpiece. The slight left-hand cutting action keeps the burr from pulling away too fast, keeping your hand steady for precise shaping.
