Total HSS Twist Drill Bit Set – 4 Pcs

Total HSS Twist Drill Bit Set – Titanium Coated, 1/4″ Hex Shank for Precision Multi-Material Drilling

The Total HSS Twist Drill Bit Set (Part No. TACSD4041) is a professional-quality accessory designed for fast and accurate drilling. The 4-piece set covers essential small-to-medium diameters (1.5mm, 2.5mm, 3.5mm, 4.0mm), perfect for drilling pilot holes and general fastening prep. Each bit is constructed from high-quality High-Speed Steel (HSS), and features an  Titanium or Gold Oxide coating for enhanced durability, reduced friction, and superior wear resistance, particularly when drilling metal.

The 1/4″ Hex Shank on each bit is a key feature, allowing for rapid, secure, and non-slip insertion into quick-change chucks, drill/drivers, and even impact drivers, maximizing efficiency on the job site.
