Ball Shape burrs are great for interior contour work, hole/bore deburring, and milling. These ball shape premium tungsten carbide burrs are designed for use with high-speed die grinders. The double-cut burrs will leave a slightly smoother finish than a single cut due to producing smaller chips as they cut away the material.
>Introduction to Machining: Milling Machine
•Work on a milling machine is most often held in a vise clamped onto the bed. To make features aligned with the edges of the stock, it's necessary to align the vise with the feed axes of the mill. To do this, mount the vise on the bed and secure it with T-bolts, but only lightly so as to permit adjustment of the orientation of the vise.
