DRILLING METAL
Use clamps to hold the workpiece. DO NOT try to hold the workpiece with your hand. The drill bit may seize the work at
any time and spin, causing damage to the machine and/or injury to you. The drill bit will break if the workpiece strikes
the column.
Clamp the workpiece firmly. Tilting, twisting, or shifting will result in a rough hole and drill bit breakage. For flat work,
lay the workpiece on a wooden base and clamp it firmly against the table. If the workpiece is of irregular shape and
cannot lie flat on the table, make sure that you clamp it securely.
