5‑Piece Wood Drill Bit Set with Titanium Coating

Reliable drilling performance for wood, plastics and metals

This 5‑piece Wood Drill Bits Drilling Tool Set is designed for accurate, clean cuts across a wide range of materials. Each bit features a heat‑treated, tempered high‑carbon steel body with a titanium‑coated HSS 4241 cutting head, providing efficient drilling and extended tool life. The intermediate chamfering drill body is made from robust 45# steel for added strength and stability during use.

Ideal for both home users and professionals, this set is particularly suitable for installing door locks, hardware, and fittings where precise, round holes are essential. The assorted diameters - 16 mm, 18.5 mm, 20 mm, 25 mm, and 30 mm - cover common sizing needs for carpentry, cabinetry, furniture assembly, and light metalwork. Use them on wood, plastic, steel, aluminum and similar metals when paired with a compatible power drill.

Why It's a Smart Choice

• Durable construction - Heat‑treated high‑carbon steel with titanium‑coated HSS cutting heads resists wear and maintains sharpness over repeated use.
• Versatile sizing - Five commonly used diameters (16/18.5/20/25/30 mm) support lock installation, hardware mounting, and general drilling tasks.
• Clean, accurate holes - Engineered geometry and a rigid 45# steel body help reduce wobble and chipping for smoother hole finishes.
