Twist Drill Bits – Precision Drilling for Every Application

Our Twist Drill Bits are engineered for precision, durability, and versatility, making them the most widely used cutting tools for drilling holes in metal, wood, plastic, and composite materials. Manufactured from high-speed steel (HSS), cobalt alloys, and carbide, these drill bits offer sharp cutting edges, excellent wear resistance, and long service life.

We provide a wide range of sizes, lengths, and point angles (118° & 135°) to meet different application requirements, from general-purpose drilling to heavy-duty industrial machining. Options such as black oxide, titanium-coated, and fully ground finishes are available to enhance cutting performance and reduce friction.

Our twist drills include (but are not limited to) the following. If you are interested in learning more about our twist drills or needing a custom solution for your project, contact us at info@bostechfastener.com.
