What are the precautions for operating a bench drill?

Precautions for using a bench drill: 1. Check whether the main power switch of the bench drill is turned on, and whether the work, fixture, and cross arm on the drill press are tightly clamped. 2. After inspection, operate according to the safety operation procedures. 3. When using the bench drill, wear labor protection equipment properly, fasten the cuffs, and gloves are strictly prohibited. Female workers or employees with long hair should wear work caps. 4. Check whether the bench drill is well grounded. 5. When drilling brittle metal materials, wear protective goggles to prevent chips from injuring people. 6. Before operation, the power switch of the bench drill must be in the off state. Carefully inspect the bench drill body, especially the parts with large stroke force, to ensure that the bench drill has no defects and does not operate with problems. 7. Wear protective equipment and goggles.
When operating a bench drill, pay attention to several key points. Safety protection must be in place, and safety goggles must be worn as metal shavings can fly off dangerously. Never wear gloves while operating, as they can get caught in the drill bit. Before starting, check if the drill bit is securely installed by testing for any wobble; if loose, tighten the screws again. Clamp the workpiece firmly using a vise or fixture to prevent slipping or deviation during drilling. Select the appropriate drilling speed based on material hardness—softer materials like aluminum require higher speeds, while steel needs slower speeds. Operate by steadily advancing the drill with the handle, applying even pressure without sudden pushes to avoid breaking the bit. Additionally, keep the workbench clear of debris, and always turn off the power before cleaning up waste shavings. For prolonged drilling, monitor heat dissipation and use coolant. For older machines, inspect the wiring for wear after each use—safety comes first, as neglecting these details can easily lead to accidents.
