About this item
  • Complete 18 pcs Countersink Drill Bit Set:Includes 5 flat head countersink drill bits (#4, ##6, #8, #10, #12), 2 replaceable flat head countersink bits (#4, #6), 2 wood plug cutters (3/8", 1/2"), 5 S2 Phillips screwdriver bits, 1 magnetic extension bit holder, 1 hex wrench – all neatly organized in a durable storage case.
  • Four-Flute Flat Head Design:The four-flute cutting edge delivers smoother cutting, less vibration, and faster drilling than single-flute designs. Achieve a precise, clean finish on wood with every use.
  • Durable & Long-Lasting:Made from HSS 4341, these tapered countersink bits provide stable cutting and efficient chip removal. Use them alone or with metal drill bits for multi-material drilling. Each bit includes an adjustable depth stop collar that locks securely to prevent slipping, ensuring consistent, controlled drilling – perfect for cabinet doors, furniture frames, and detailed trim work.
  • Hidden Finish for Professional Results:Includes two plug cutters to create custom wood plugs that conceal screw holes – ideal for cabinetry, furniture building, decorative woodworking. Sharp chamfered edges produce smooth pilot holes and clean countersink seating, while the high-carbon plug cutters deliver a concealed, professional finish for any woodworking repair when paired with a countersink drill bit.
  • Adjustable Control & Universal Compatibility:The 1/4" hex shank fits impact drivers, electric drills, hand drills, and drill presses. Adjustable collars ensure consistent, repeatable countersink depth whether you’re using a single bit or the full set. Designed with durable construction and compact storage, this versatile set delivers reliable performance for workshop, home DIY, and job site drilling tasks.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
