Common specifications

Key specifications

Dimensions in mm: d1 head diameter, l2 cut length, d2 shank diameter, l1 overall length. Each item number is one head size.

Selecting the right option

Choose the head size and shank to suit the job and your tool; the table lists each item number with its dimensions. The catalogue gives a cutting speed of 450 to 750 m/min for steels up to 1,200 N/mm2, and the rotational speed follows from the burr diameter (manufacturer-stated). Do not exceed the maximum permitted rotational speed, observe the recommended rotational speed (especially with long shanks), wear eye and hearing protection and a dust mask, and do not use a damaged burr or use the burr for cutting (manufacturer-stated).
