When to Use Tungsten Carbide Drill Bits

Tungsten carbide drill bits undergo a lot of stress when drilling a hole. The high-speed rotation of drill bits generates friction that, in turn, generates heat. The friction between drill bit and material leaves drill bits slightly duller after each use. The heating and cooling of the drill bit material can weaken the internal structure of the bit over time.

The Common Drill BitTungsten carbide drill bits
Common home repair drill bits are made of steel or High Speed Steel (HSS). Although inexpensive, common steel drill bits tend to wear out or break very quickly. HSS drill bits last longer than steel, but are more expensive. These types of drill bits are most effective when used on wood, drywall or plastics.

A Bit Stronger
Coated drill bits use another, harder material to coat steel or HSS drill bits. Titanium carbide or titanium nitride coatings can increase the lifespan of a drill bit by two to three times. These types of drill bits are useful when drilling hardwoods or thin metals.

Gets Tough
Tungsten carbide drill bits are among the strongest drill bits available for home use. Carbide drill bits are more expensive than steel or titanium coated drill bits, but will last longer and stay sharper.

Tungsten carbide drill bits are absolutely necessary when drilling stainless steel or other high-density materials. No other drill bit can handle the job.

Regardless of the material that you usually drill, a carbide drill bit will last up to 25 times longer than a common steel bit. This can make carbide drill bits an economical choice for woodworking, furniture building or other large-scale projects.

When cutting dense material, use a cutting lubricant to avoid generating excessive heat. Overheating a carbide drill bit will shorten its lifespan. Always let the drill bit do the work. Applying too much pressure will quickly dull your drill bit.
