Choose the working shape first
The shape determines which area of the working surface can make contact. Compare the application stated for the model rather than relying on its resemblance to another bit. A ball, flame-like or differently shaped head should be selected for the task described for that particular product.
Read the dimensions accurately
In the confirmed DIVNA series, a code such as 856.001.035.035 includes a working height of 3.5 mm and a working diameter of 3.5 mm. Those figures describe the head, not the shank. Check all groups of the code when comparing sizes.
Stripe and grade
The 856, 866 and 836 series correspond to red, blue and yellow stripes respectively. Use the grade explicitly stated in the product description; color alone should not be used to assign an abrasive grade. These coding rules apply to the specified DIVNA series and should not be generalized to other manufacturers.
