How to Use Woodworking Countersink Drill Bit?
●Attach to any Power Bench or Hand drill driver.
●When Woodworking or Building Molding, enlarge and bevel the rim of a drilled hole
so that a screw, nail, or bolt can be inserted flush with the surface you are working on.
●Example: Hinges - the bits also wipe away any burr left from any application,
thereby improving the finish and removing hazardous edges.

▲ Special Note：
●The best use of this product is to use a bench drill, because the hand electric drill is not fixed in
the operation process, the drill bit (especially the 3mm and 4mm) is prone to bend and break!!!
●Try to keep the drill vertical while drilling, so as not to be uneven.
