A drill bit lasts long due to a combination of superior materials, smart design, protective coatings, and proper usage.
- Material:Better bits use harder, heat-resistant materials like Cobalt Steel (HSS-Co)or Carbide, which stay sharp much longer than standard steel.
- Design:Precision-engineered geometry—the angle of the tip and the spiral of the flutes—ensures efficient cutting and easy waste removal, reducing stress and heat.
- Coating:Hard, lubricious coatings like Titanium Nitride (TiN)or Diamond provide a protective “armor” that drastically reduces wear and friction.
- Proper Use:You maximize lifespan by:
- Using the correct speed (slow for metal, fast for wood).
- Applying firm, steady pressure (don’t force it).
- Using cutting fluid for metal to manage heat.
- Ensuring the bit is sharp and not allowed to overheat.
