DESIGN & QUALITY: No More Splitting Woods! The Ultimate 2-in-1 countersink drill bit design Made of Steel so the bits have sharp tips and are able to sustain through heat and pressure without breaking/shattering and damaging the panel or beam you are building - Bit sizes are carved onto the drill bits for identification.
NICE APPEARANCE: The drill bits drills pilot holes nicely and accurately with precision time and time again getting a precise cone shaped hole on each burr, as a result you will get a nice smooth surface on any type of hard, soft wood or aluminum.
USES: 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, , 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.
But why pre-drill with 1 bit & countersink with another 1 when you can have it in 1 easy tool?!
OUR SOLUTION:
The 3-in-1 Counter-sinking Drill Bits lets you Pre-drill & cone-shape the hole where the screw heads will countersunk & sit comfortably below the surface of the surroundings.
Kit also includes stop collars for controlling drill bit depth to a precise setting.
It's recommended to use drill collars with a lubricant to prevent burning of the material surface.
ADJUSTABLE:
Both the Countersink bits & the collars have hex nuts for easy adjusting tightening & accurate positioning.
Kit comes with the Correct Hex Wrench for tightening the nuts.
Countersink may also be used to remove burr left from a drilling/tapping operation thereby improving the finish of the project & removing any hazardous sharp edges.
(Countersink unlike counterbore makes a cone shaped hole while bore produces a Flat-bottom rounded hole.)
