Case Study: Real Business, Real Results
Located in Dayton, Ohio, Precision Metalworks upgraded their rotary burr tools to improve finish quality and cut efficiency.
"Switching to the SD-3L6 with the double cut option has given us much smoother finishes and far better control on our grinders. It’s noticeably reduced rework time and helped us meet tight deadlines with confidence."

Why the Double Cut Provides Exceptional Smoothness and Control
The double cut on this burr combines right and left-hand spiral flutes, creating a cross-cutting pattern. Imagine rubbing sandpaper in two directions rather than one – it smooths rough spots more efficiently and reduces vibration. This effect not only leaves a cleaner finish but also helps you steer the tool with precision, so you can shape your workpiece exactly as planned without unexpected skips or chatter.
