Abstract
Overview
ISO 10898:2016 is an international standard published by the International Organization for Standardization (ISO) that specifies the dimensions and technical requirements for spot drills. This standard covers spot drills made from high-speed steel and hardmetal materials featuring point angles of 90° or 120°. Spot drills are precision tools used primarily for creating accurate starter holes in metalworking before further drilling operations, ensuring proper drill guidance and reducing deflection.
