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.
