Product Details
✓【LONG-LASTING TCT + TOUGH M2 HSS】 Five 82° two-flute tungsten carbide-tipped cutters combine wear-resistant cutting edges with tough M2 HSS pilot bits. This material pairing helps maintain sharpness, drill stable pilot holes, and cut clean countersinks for flush-fitting flat-head screws.
✓【PRECISE DEPTH, LESS SURFACE WEAR】 Adjust the pilot-hole depth and countersink depth independently for different screws and materials. The ball-bearing depth stop reduces drag when it contacts the workpiece, helping prevent over-drilling while reducing circular marks, scratches, and heat discoloration.
✓【9-PIECE SET, READY TO WORK】 Includes five two-flute TCT countersink bits with M2 HSS pilot drills in 1/8" × 3/8", 9/64" × 3/8", 5/32" × 3/8", 11/64" × 1/2", and 3/16" × 1/2", plus 1 adjustable ball-bearing depth stop, 1 L-wrench, 1 S2 PH2 driver bit, and 1 storage case.
✓【SMOOTHER CUTS, LESS CLOGGING】 Wide two-flute channels give chips more room to escape, helping reduce clogging, friction, and heat buildup. Sharp 82° cutting edges create smoother countersink openings with less sanding and cleanup afterward.
✓【ONE SET FOR MORE MATERIALS】 Suitable for natural wood, plywood, MDF, particleboard, engineered boards, plastic, aluminum, and other non-ferrous metals. Ideal for furniture assembly, cabinetry, renovation, and professional or DIY countersinking projects.
✓【200 RPM FOR CLEANER RESULTS】 For smoother countersink edges, operate the drill at approximately 200 RPM with steady, controlled pressure. Avoid excessive speed or force; proper low-speed operation helps reduce heat and preserve cutter sharpness.
