PFERD 27521 Carbide Bur - Ball Shape, MICRO Cut 1/4" x 3/16" x 1/4" Shank - SD-1
PFERD produces an extensive range of top quality carbide burs and bi-metal hole saws. PFERD burs deliver very high stock removal performance over their entire service life, providing outstanding results in minimal time.
Carbide burs with MICRO cut are specifically designed for finishing and are used in areas in which abrasive mounted points are usually used. They offer a higher stock removal rate and produce a high surface quality, particularly compared with conventionally milled surfaces.
They also operate with low vibration and little noise. They maintain their geometry over their entire service life, and are well suited to manual and machine applications. Almost all materials up to a hardness of 940 HV (68 HRC) can be machined.
