1.Top Quality material components highly durable:Tapered drill bit HSS M2, by far the most popular High Speed Steel, for its high toughness, wear resistance, and good cutting edge retention;Drill, countersink and counterbore in 1 step; the countersink cutter doesn't clog up providing superior speed and clean finish
2.Adjustable 4-cutter counter bore cuts and clears chips quicker for fast, smooth countersinking; the countersink works effortlessly even after many uses; it makes clean and consistent tapered holes for screws without the need of a stop collar; counterbore size 5/16", plug size 5/16"

3.Tapered drill pointed tip with widened flutes for drilling fast, clean pilot holes and ensures tight fit for screws; tapered drill bit can be replaced with a replacement bit of the same type and size FTG 2329 for extended life;Quality built counter bore attaches to flats on shank with 2 hex screws for a secure fit and can be adjusted for controlled pilot hole depth
4.Universal 1/4 inch hex shank prevents slipping in standard chucks and is compatible with all 1/4 inch quick-change chucks, including impact drills;

5.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, 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.

6.Flute length and drill bit diameter are both adjustable upon request.

7.Round Shank Countersink Bit also avalable.
