How to read the model number

The catalog page “Detailed explanation of the model” reads a code left to right as series, cutter type, length mark, flutes, helix angle, cutting diameter, corner radius, cutting length, overall length and shank diameter. The original diagram is reproduced here:

Koves model-number key: how a carbide end mill code is read — series (HP/HM/HY/HS/HR/ALU/DIA/CO-MAX), cutter type (B/E/R/RE), length mark (L), flutes, helix angle, cutting diameter, corner radius, cutting length, overall length and shank diameter
