TO DRILL DIFFERENT MATERIALS
FEEDING THE DRILL BIT
• Pull down on the feed handles with only enough force to allow the
drill bit to cut.
• FEEDING TOO RAPIDLY could stall the motor, cause the belt to slip,
damage the workpiece, or break the drill bit.
• FEEDING TOO SLOWLY could cause the drill bit to heat up and burn
the workpiece.
DRILLING METAL
• Use metal-piercing twist drill bits.
• It is always necessary to lubricate the tip of the drill with oil to
prevent overheating the drill bit.
• All metal workpieces should be clamped down securely. Any tilting,
twisting, or shifting causes a rough drill hole, and increases the
potential of drill bit breakage.
• Never hold a metal workpiece with your bare hands. The cutting
edge of the drill bit may seize the workpiece and throw it, causing
injury. The drill bit will break if the metal piece hits the column.
• If the metal is flat, clamp a piece of wood under it to prevent
turning. If it cannot be laid flat on the table, then it should be
blocked and clamped.
DRILLING WOOD
• Brad point bits are preferred. Metal piercing twist bits may be used
on wood.
• Do not use auger bits which turn so rapidly that they can lift the
workpiece off the table and whirl it around.
• Always protect the drill bit by positioning the table so that the drill bit
will enter the centre hole when drilling through the workpiece.
• To prevent splintering, feed drill bit slowly when the bit is about to
cut through to the reverse side of the workpiece.
• To reduce splintering and protect the point of the bit, use scrap
wood as a backing or a base block under the workpiece.
