Using Drill Bit Speed Chart
The chart shown in Figure 31 is intended as a
generic guide only. Always follow the manufac-
turer's speed recommendations if provided with
your drill bits, cutters, or hole saws. Exceeding
the recommended speeds may be dangerous to
the operator.
The speeds shown here are intended to get you
started. The optimum speed will always depend
on various factors, including tool diameter, drilling
pressure, material hardness, material quality, and
desired finish.
Often, when drilling materials other than wood,
some type of lubrication is necessary.
Lubrication Suggestions
Wood ...........................................................None
Plastics
............................................Soapy Water
Brass
...............................Water-Based Lubricant
Aluminum
..................... Paraffin-Based Lubricant
Mild Steel
............................. Oil-Based Lubricant
Figure 31. Drill bit speed chart (RPMs).
Larger bits turning at slower speeds tend
to grab workpiece aggressively. This can
result in operator's hand being pulled into
bit or workpiece being thrown with great
force. Always clamp workpiece to table to
prevent reduce risk of injury.
