Threaded Drill Bits
Threaded Aircraft Drill Bits
Our threaded drill bits are the industry standard 1/4” x 28 threaded male.
Quality
Our bits are quality-approved at every major aircraft manufacturer. All of the threaded aircraft drill bits at the Yardstore are USA-made. The 135° split point is designed to penetrate on contact and reduce “walking”, which can break bits and damage materials.
The cobalt bits are produced from industrial-grade NAS 965 cobalt steel. They have superior hardness for high-temperature applications and long life. They are designed for use with tough, high-strength materials.
The Yardstore’s threaded drill bits are made of the best high-speed heat-resistant steel. Their oxide finish creates a porous layer that holds cutting oil , providing abrasion resistance and improving chip flow.
