1. Carbon Steel Drill Bit. – Low carbon steel: this is the cheapest option for making a drill bit, due to their poor tempers, low carbon steel drill bits are usually used for drilling softwood and some plastics, and require to be sharpened often to extend the lifespan. – High carbon steel: a better material than low carbon steel, high ...
Hardened steel, known for its high durability and resistance to wear and tear, poses a unique challenge. Unlike softer materials, it requires specific drill bits that can penetrate without losing their edge or causing damage to the material or the tool.
Titanium-coated HSS drill bits produce less friction. They're tougher than basic HSS bits and stay sharp longer. They work for drilling wood, metal, fiberglass and PVC. Carbide-tipped drill bits stay sharp much longer than steel, HSS or titanium bits. They're effective for drilling tile and masonry.
