DRILLING SPEEDS
There are a few important factors to keep in mind when determining the best drilling speed:
• Material type
• Hole size
• Drill bit or cutter type
• Quality desired
Smaller drill bits require greater speed than larger drill bits. Softer materials require greater speed than harder
materials.
DRILLING WOOD
• Brad point bits are preferred. Metal piercing twist bits may be used on wood.
• Do not use auger bits. Auger bits turn so rapidly that they can lift the workpiece off of the table and whirl it
around.
• Always protect the drill bit by positioning the table so that the drill bit will enter the center hole when drilling
through the workpiece.
• To prevent splintering, feed the drill bit slowly right as the bit is about to cut through to the backside 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.
FEEDING THE DRILL BIT
• Pull down on the feed handles with only enough force to allow the drill bit to cut.
• Feeding too rapidly might stall the motor, cause the belt to slip, damage the workpiece, or break the drill bit.
• Feeding too slowly will cause the drill bit to heat up and burn the workpiece.
