60 HSS Titanium High-Speed Steel Twist Drill Bits – Metric Micro Milling Bit Set 1 1.5 2 2.5 3 3.5 mm for Electric Drills and Mini Drills

Material: High-speed steel with titanium coating.

The drill bits are smooth and coated, resulting in a uniformly sharp and durable HSS high-speed steel.

6 different diameters to choose from: 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 10 pieces of each size.

Titanium coating improves the surface hardness of the drill bit, enhances machining accuracy, improves the surface quality, reduces the coefficient of friction with the workpiece, and improves wear resistance.

Suitable for drilling holes in a variety of surfaces, including aluminum, wood, and plastic. Ideal for DIY projects, crafts, and general building/engineering applications.
