Weldon Steel

A ball end mill is a CNC cutting tool with a hemispherical (ball-shaped) cutting end. This allows it to machine complex 3D contours and surfaces, as well as perform profiling, slotting with a radius, pocketing with radiused corners, engraving, and creating fillets. Key advantages include its ability to create intricate shapes and a smooth surface finish. They come in various materials, coatings, flute counts, and sizes to suit different machining needs.

Counterbores, sometimes called spotfacers, create a flat-bottomed cavity at the top of an existing hole so that a bolt, nut, or other part is hidden beneath or sits flush with the top of the hole when installed into it.

Countersinks expand the top of an existing hole in a workpiece to allow countersinking screws to install flush with the surface of the workpiece. This helps prevent the workpiece material from swelling when a screw is inserted and tightened down.

Reid Supply has a range of ball end mills, square end mills, corner radius end mills, roughing end mills and more.
