Tips For Using & Maintaining Forstner Bits
bits should ALWAYS be used in a Drill Press
accurate positioning (when using Forstners with little or
no center spur), you should always draw or scribe your circle
on your workpiece before boring
follow the manufacturer's speed recommendations. Forstners
usually work best at slow speeds...especially when boring
large diameter holes or working with hard woods. Excess
speed will burn the bit and destroy the temper of the steel.
Reducer may be required for certain operations .
drill metal with a Forstner Bit
drilling deeper than the Bit rim, always retract the bit
frequently to clear the chips and avoid burning.
sharpen the outside of the rim on a Forstner Bit, as this
will reduce the size of the hole it will drill. In fact,
it's best to have Forstners PROFESSIONALLY sharpened.
possible, clamp your workpiece in position when using Forstners
