1/2" Reduced Shank HSS Twist Drill Bits (12–39 mm, for Steel & Metal)

 

Introduction

 
These 1/2" reduced-shank twist drill bits are heavy-duty cutting tools designed for drilling in a wide range of metals and materials. Available in two high-speed steel grades—cobalt alloyed HSS-6542 and standard HSS-4341—they offer durability, precision, and reliable performance for both light and demanding drilling tasks. The reduced shank design allows larger-diameter bits to fit standard 1/2" chucks, making them versatile for use in hand drills, drill presses, and other power tools.
