➤ RELATIONSHIP BETWEEN HELIX ANGLE AND PITCH

➤ CLASSIFICATION SYSTEM OF PITCH

In order to ensure the pitch tolerance of the helix rod, the classification of pitch is based on the helix angle tolerance. In order to achieve the accuracy of pitch classification, the pitch of each helix rod is tested and then classified. Conventional helix rods use the Level 3 classification system for pitch categorization, while deep hole drilling (for helix rods with a diameter‑to‑length ratio greater than 15) uses a Level 6 classification system for pitch categorization;
