Description
The best drill bits for metal are made from robust materials such as High-Speed Steel (HSS), Cobalt, and Carbide. HSS bits are versatile and suitable for various metals, whereas Cobalt bits excel in hardness and heat resistance, making them ideal for tougher metals. Carbide bits are the hardest and most durable, but also the most brittle.
The design features that enhance drill bit performance include a split point tip, which minimizes “walking” and allows for a cleaner start, and an appropriate tip angle, typically between 118 and 135 degrees, tailored to the hardness of the metal being drilled.
Flutes are essential for chip removal and heat dissipation, with coatings such as black oxide, titanium, and diamond powder available to reduce friction and extend the bit’s life.
Additionally, the shank design—often round or hex-shaped—determines how well the bit fits into the drill, affecting grip and precision. Specialized bits like twist bits, step bits, and hole saws may be selected based on the specific job requirements.
Durability is also key, with the best metal drill bits featuring design enhancements that resist wear and tear, thereby maintaining their cutting ability over time. Selecting the right drill bit for metal depends on finding the optimum balance of material, design, and durability for the task at hand.
