About this item
- 📝【6PCS Countersink Drill Bit Set】This complete set includes 4 HSS tapered countersink bits (2.8mm, 3.2mm, 3.5mm, 4.0mm centre drills), each paired with an 82° 4-flute counterbore (8mm for 2.8/3.2mm bits; 10mm for 3.5/4.0mm bits). Also includes a 1/4" hex shank extension handle and a hex wrench for quick bit changes. Ideal for precise woodworking, cabinetry, and multi-diameter drilling applications.
- 📮【Premium Carbon Steel & Aluminium】The countersink bits are crafted from durable carbon steel, offering excellent wear resistance and heat tolerance – ensuring they stay sharp even during repetitive use. The adjustable depth stop collar is made from rust-proof aluminium alloy with a green scratch-resistant rubber pad, protecting your workpiece surface from damage.
- 📝【Adjustable Depth Stop with Bearing】Featuring an upgraded aluminium stop collar with a built-in bearing, this set allows smooth and accurate depth adjustment up to 1.3 inches. The scale‑marked collar lets you set consistent drilling depths every time, preventing over‑drilling and ensuring clean, professional results in softwood, hardwood, or MDF.
- 📮【Fast Chip Removal & Drilling】The spiral flute design rapidly expels chips from the hole, reducing friction and heat build‑up. This ensures faster, cleaner drilling and extends bit life. Whether you’re a DIY enthusiast or a professional, you’ll appreciate the efficiency and precision this set delivers.
- 📝【Versatile Use – Wood, MDF & DIY】Perfect for furniture assembly, cabinet installation, decking, and general woodworking. The compact storage case keeps all 6 pieces organised and portable. Suitable for natural wood, particleboard, plywood, and fibreboard – a must‑have addition to any toolkit.
- ⚠️ Note: For best results on hardwood, we recommend using a slower speed (approx. 200 RPM) to maintain a clean edge. Not suitable for drilling into metal or steel.

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.
