In parallel with material improvements, design optimization played a critical role in enhancing drill rod performancemine extension drill rod. The introduction of tapered threads reduced stress concentrations at thread connections, minimizing the risk of fractures. Additionally, the implementation of advanced coatings such as titanium carbonitride (TiCN) provided an extra layer of protection against abrasion and wear, extending the service life of the rods significantly.

Taper bits, also known as dovetail bits, are named after their unique shape that tapers from a wider diameter at the shank end to a narrower one at the cutting edge. This design enables them to create a gradual slope or angle, which is particularly useful for creating dovetail joints, staircase spindles, and furniture legs. The percentage indicated as taper% refers to the rate at which the bit narrows down, determining the steepness of the angle created.
