This adjustable countersink features a Tungsten Carbide Tipped (TCT) design suitable for plywood, particle boards, and plastics. It is supplied with a High-Speed Steel (HSS) slow spiral drill bit for durability and reliable performance. The countersink is fully adjustable using the included hex key. Please note: this countersink is not suitable for ferrous or non-ferrous metals. For optimal results, use at drilling speeds only and ensure drill flutes are aligned with countersink flutes. Replacement twist drills should be of the slow spiral type.
