Drill Nomenclature and Geometry - NEMES
neme-s.orgDrill Nomenclature-Points• Elements of Drill Points • Lip Relief Angle – Varies with the diameter of the drill and hardness of the material – On larger diameters and drills for harder materials, lip relief is decreased to as low as 8° – Drills for soft materials and small diameters have high relief angles up to 24° – Lip relief angles are measured across the margin
