Common specifications

Key specifications

Each item number is a separate combination of head size. Optimum and maximum speeds depend on the head size and shank, so each item lists its own.

Selecting the right option

Match the shank to your collet (6 mm shank). A higher grit number is a finer abrasive. Check the head size and speeds against the table before ordering. The catalogue states that all PFERD TOOLS mounted points are approved for a maximum operating speed of 50 m/s, that the maximum permitted rotational speeds for each shank length and shank diameter are defined in DIN 69170 based on EN 12413 to avoid buckling of the shank, and that at least 10 mm of the shank must be clamped. Wear eye protection, hearing protection, a dust mask and gloves (manufacturer-stated).
