OPERATION

this document before set up or use of this
product.
1. Select the desired size Hole Saw and either the
Large or Small Mandrel (not included with 68111

2. NOTE: The 2-1/2" and 2-1/8" Hole Saws will
need to be unthreaded from one another.
CAUTION! Wear heavy-duty work gloves when
unthreading.
3. The correct size Mandrel will t exactly into the
Hole Saw.
4. NOTE: The Adapter will be needed to attach the
Small Mandrel to medium size Hole Saws (such
as 1-3/8” and 1-1/2” sizes.) Carefully thread
the Adapter through the top of the Hole Saw
and then thread the Small Mandrel through the
bottom so that it screws into the Adapter.
5. To attach larger Hole Saws to the Large Mandrel,
thread Hole Saw to top of Mandrel until mounting
holes at base of the Saw align with the mounting
tabs on Mandrel. Twist the bottom base of Large
Mandrel until the tabs extend into the Saw’s
mounting Holes and the two pieces are securely
fastened together.
6. Open jaws of drill chuck (not supplied).
7. Place the Mandrel shaft completely into the
chuck and securely tighten the chuck.
8. Holding the drill at 90 degrees to the stock, set
the Hole Saw on the stock.
9. Press the drill’s trigger switch to turn it on.
10. If the drill is a variable speed type, start cutting
the stock slowly until the circle groove is made in
the stock. Then cut faster.
11. When the hole is cut, release the trigger switch
and wait for Hole Saw to come to a complete
stop before removing it from the stock.
12. Remove Hole Saw from drilling tool chuck.
13. Remove Hole Saw from Mandrel and clean off
Hole Saw with a cloth. Place Hole Saw and
Mandrel back in carrying case. If a different
sized Hole Saw is needed, attach it to Mandrel.
14. CAUTION! Verify all Hole Saws are returned to
case when work is complete.

or broken. Always make sure the bit is securely
held in place after being reinstalled.
