The AIYI 13-Piece Twist Drill Bit Set is designed for precision, durability and professional performance. Manufactured from hardened and tempered M2 High-Speed Steel (HSS), these drill bits provide reliable strength for drilling into metal, wood and plastic.
Each bit features an advanced 135° split point tip, which helps prevent “walking” on the surface and allows for faster, more accurate penetration. The titanium coating reduces friction and heat buildup during drilling, resulting in smoother operation and extended tool life — lasting significantly longer than standard drill bits.
Precision ground for accuracy and consistent performance, these drill bits can also be resharpened for extended usability. Supplied in a convenient storage case, this set is ideal for workshops, construction sites, DIY projects and general maintenance applications.
Includes sizes:
1.5 mm, 2.0 mm, 2.5 mm, 3.0 mm, 3.2 mm, 3.5 mm, 4.0 mm, 4.5 mm, 4.8 mm, 5.0 mm, 5.5 mm, 6.0 mm, 6.5 mm
