Lytool Hex Countersink Drill Bit Set 6.35mm 🛠
Product description
This set of adjustable hex countersink drill bits from Lytool is aimed at woodworking tasks where neat, recessed screw heads and precise pilot holes are important. It includes five quick-change hex countersink tools with five replaceable drill bits, allowing you to match pilot hole sizes to different screw gauges for cabinetry, joinery and general DIY work.
Key Points
The kit offers five drill diameters: 2.8mm, 3mm, 3.2mm, 3.5mm and 4mm, together with a 10mm counter-bore diameter to create consistent recesses for screw heads. According to the manufacturer, the high-speed steel cutting edges are sharp and wear-resistant, which helps produce smooth holes and a closer screw fit. The base of the countersink is made from 45# steel to improve durability and reduce the risk of breakage during repetitive drilling. 🔧

Practical Tips
To adjust the countersink depth use the supplied hex wrench to loosen or tighten the retaining screws and slide the cutter to the required position. For accurate positioning mark the centre with a punch before drilling and keep the drill perpendicular to the workpiece to avoid bending or uneven holes. For best results work at moderate speed and avoid excessive pressure which can blunt the cutting edge more quickly. 🪚
Usage Recommendations
These countersink bits are suited to timber and wood-based materials such as compressed board, MDF, pine and some plastics. They should not be used on glass, metal, concrete or plasterboard as these materials can damage the cutting edges. The set is compatible with common chucks found on cordless drills, hand drills and bench drills, thanks to the quick-change 6.35mm hex shank format. Note that if you use long screws or very hard timbers you may need to pre-drill deeper pilot holes and check screw fit frequently to avoid splitting the material. 🔩
