9PCS Countersink Drill Bit Set with Adjustable Depth Stop Collar
6 sold in last 24 hours
- 【TUNGSTEN CARBIDE CUTTERS + M2 HSS PILOT BITS】 Five 82° two-flute TCT (tungsten carbide-tipped) cutters stay sharp longer and deliver up to 5× the service life of standard HSS countersink cutters, reducing the need for frequent replacements. M2 HSS pilot bits provide toughness and drilling stability for clean, accurate countersinks that fit flat-head screws.
- 【PRECISE DEPTH CONTROL WITH LESS SURFACE WEAR】 Set drilling and countersinking depths independently. The ball-bearing depth stop reduces friction when contacting the workpiece, helping prevent over-drilling, scratches and burn marks while reducing surface wear by up to 90% versus traditional stop collars.
- 【COMPLETE 9-PIECE SET】 Includes five 2-flute TCT countersink bits with M2 HSS pilot drills in sizes 1/8" × 3/8", 9/64" × 3/8", 5/32" × 3/8", 11/64" × 1/2" and 3/16" × 1/2", plus an adjustable ball-bearing depth stop, L-wrench, S2 PH2 driver bit and storage case.
- 【TCT 2-FLUTE UPGRADE OVER CARBON STEEL】 Compared with common four-flute carbon-steel cutters, the harder TCT cutting edges provide greater wear resistance, while the wider two-flute channels improve chip removal and help reduce clogging, heat buildup and discoloration.
- 【WIDE MATERIAL COMPATIBILITY】 Suitable for natural and engineered wood, plywood, MDF, particleboard, plastic, aluminum and non-ferrous metals. Ideal for furniture assembly, cabinetry, renovation and professional or DIY countersinking projects.
- 【PRO TIP: USE APPROXIMATELY 200 RPM】 For cleaner, smoother countersink edges, operate the drill at approximately 200 RPM with steady, controlled pressure. Proper low-speed operation helps reduce heat and extends cutter life.
