M2 HSS pilot bits provide toughness and drilling stability for clean, accurate countersinks that fit flat-head screws.\u003c\/li\u003e\n\u003cli\u003ePRECISE 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.\u003c\/li\u003e\n\u003cli\u003eCOMPLETE 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.\u003c\/li\u003e\n\u003cli\u003eTCT 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.\u003c\/li\u003e\n\u003cli\u003eWIDE MATERIAL COMPATIBILITY Suitable for natural and engineered wood, plywood, MDF, particleboard, plastic, aluminum and non-ferrous metals.
