What people don’t love
Tips may break quickly when used on tougher metals like 16-gauge steel.
Smaller bits can be fragile and require careful use.
Better suited for wood and lighter-duty applications rather than thick metal.
Reliable countersink drill bits ideal for woodworking and light metal tasks but may lack durability on heavy steel.
If you want cleaner, more professional-looking screw holes, the WORKPRO 5-Pack Countersink Drill Bit Set combines drilling and countersinking in one convenient setup. Made from M2 high speed steel (HSS) and built with a 4-flute chamfer cutter, these bits are designed to help reduce burrs and leave a smooth, finished edge.

This set includes five common sizes—#4 (7/64 in), #6 (9/64 in), #8 (11/64 in), #10 (3/16 in), and #12 (7/32 in)—making it a practical pick for everything from cabinetry and carpentry to general home repairs. The countersink depth is adjustable: set your desired drill length and tighten using the included hex key for repeatable results across multiple holes.
Recommended for wood, plywood, PVC, and plastic, these uncoated, hex-shank countersink drill bits are a solid choice for DIYers and pros who want consistent countersinks without switching between separate tools.
M2 high speed steel (HSS) construction for hardness and wear resistance
