50-Piece HSS Titanium-Coated Twist Drill Bit Set

Versatile 50-piece drill bit set for accurate, clean drilling

This 50-piece twist drill bit set is designed for consistent performance across a wide range of light-duty drilling tasks. Manufactured from high-speed steel (HSS) with a titanium-coated surface, these bits offer improved wear resistance and smoother drilling compared to uncoated steel, making them suitable for wood, plastics, and soft metals such as aluminum.

The set includes five frequently used diameters, each supplied in multiples for convenience and replacement: 10 x 1.0 mm, 10 x 1.5 mm, 10 x 2.0 mm, 10 x 2.5 mm, and 10 x 3.0 mm. The spiral (twist) flute design helps clear chips efficiently, supports accurate hole positioning, and provides a clean finish when used with appropriate drilling speeds. Compact and lightweight, this set is easy to store in a toolbox or carry to job sites, making it a practical choice for hobbyists, DIY users, and professionals who need a reliable selection of small-diameter bits.

A: Yes. The bits have standard cylindrical shanks and can be used with most corded and cordless drills that accept small-diameter bits.

Q: Can these bits be resharpened?
A: Yes, HSS bits can be resharpened with the correct tools and technique. Take care not to overheat the cutting edge during sharpening.

Q: Are they suitable for heavy industrial use?
A: This set is best suited for light to medium-duty tasks, general workshop work, and DIY projects rather than continuous heavy industrial production.
