Introduction

★ What Is a Hex Shank Drill Bit Set?
This blister-packed set combines several metric twist drill sizes with a quick-change hex shank. The six-sided shank engages positively with a compatible chuck or bit holder, helping reduce shank slippage and making changes between drill bits and screwdriver bits faster. It is a practical choice for installation, repair, maintenance and everyday workshop drilling.

★ HSS-M2 with Titanium Nitride (TiN) Coating
The drill bits are made from HSS-M2 high-speed steel and finished with a gold-colored titanium nitride coating. The coating increases surface hardness and reduces friction at the cutting surface, supporting smoother chip flow and consistent general-purpose drilling performance. The gold finish also makes the set easy to identify in a toolbox or retail display.
