Rockler 18-Pc. Self-Centering & Countersink Set
18-piece Rockler/Insty-Drive self-centering and countersink set lets you convert from drilling and countersinking to installing perfectly centered hinge screws in a matter of seconds - without re-chucking any bits! The 18-Piece set includes #6, #8 and #10 HSS 2-flute tapered hex shank bits with 4-flute countersinks; #6, #8 and #10 hex shank HSS self-centering bits; Rockler's Insty-Driver; 10 of the most popular drive bits; and a nylon pouch with belt loop. Switch from drilling to driving instantly! Just drill the pilot hole, slip on the Insty-Driver and drive home the screws. Components are engineered to meet the highest standards for use in industrial applications. All Rockler/Insty-Drive bits are precision-ground high speed steel that resist wear and overheating, thus keeping a sharp edge longer. Bits can be resharpened easily on a bench grinder. Inluded self-centering bits ensure accurate hinge and hardware installation every time. Countersink has a 4 flute design for smooth, clean holes that do not require sanding. Taper drill bit is adjustable to match length of screw and is held with 1 or 2 hex set screws. How the Rockler/Insty-Drive System Works: Step 1: Drill the pilot hole with the countersink bits or the self-centering bits, which both have a hex shank to prevent slipping. Step 2: Slip on the Rockler Insty-Driver which fits over Rockler countersink and self-centering bits. Magnetic tip holds all 1/4'' style insert bits and screws. Step 3: Drive home the screws. Then slip off the Insty-Driver and do it again. You'll get fast and accurate hardware installation every time!
