Suitable for drilling materials:

Instructions for use:

• Before drilling a deep hole, you must pre-drill a shorter intermediate length hole of the same specification to reduce the pressure on the drill bit.
• When drilling, it is necessary to maintain a stable pressure and remove the drill bit from the hole frequently to remove debris. Use a slow speed to drill harder materials to extend the life of the drill bit.
• Different drilling speeds are used depending on the model of the electric drill. Generally speaking, regardless of the drill bit specifications, the recommended drill speed is 300-400 revolutions per minute.
• Do not use too much force on the hammer drill when using it. Just use normal force to avoid hand fatigue.
