The Tri Cone – #1 Over 2 Centuries…for 3 Reasons

tri-cone-drilling-heads-rocks-bitsThey say there’s strength in numbers, and the tri cone is a perfect example. Its strong performance in project after project can be attributed to a number of factors. But since “good things come in threes”, here are three key reasons for its popularity and success.

3 Heads

They say that two heads are better than one, but why stop there? In 1933, engineers from the Sharp-Hughes Tool Company developed the first tri cone. They wanted to improve the company’s current two-cone design and, in spite of working during the Great Depression, they did so in bold fashion. By adding a third cone, they produced the ultimate drill bit. Sporting three cone shaped heads, each equipped with several rows of teeth, this design became extremely versatile, offering quality and consistency that was unmatched in the industry.

Over time, the tri cone has been enhanced with sharper teeth and better bearings. It can now drill deeper, longer and better than ever before. But the key qualities that separated it from the competition remain the same. Not only is it easier to control and maintain, but it can tackle the most challenging rock formations without missing a beat. Perhaps most importantly, it is cost effective, proving to be more affordable than other bits of lesser quality.

So tri cone buyers don’t get what they pay for. They get more.

3 Rocks

A big factor in the success of the tri cone is its ability to perform at a high level regardless of the rock formation involved. A tri cone is the perfect choice for soft formations such as sand, clay or soft limestone, and works equally well in medium formations including calcites, dolomites, limestone and hard shale.

For hard rock such as granite and mudstone, a sealed bearing tri cone is the drill bit of choice, as it’s extremely durable and less likely to disrupt your drilling process.

3 Bits

Because drilling projects come in all shapes and sizes, there are three types of tri cone bits available to accommodate a variety of jobs.

1. Roller bearing bits utilize three cones spinning independently. They are most often used to drill oil, gas or shallow water wells.

2. Sealer roller bits have a seal that protects each drill bit from damage during the drilling process. Although the seal will eventually be worn away from constant use, this model can still be employed as a roller bearing bit in future projects.

3. Sealed journal bits are the strongest and most durable of the three types. With the proper drilling lubrication, they can thrive in the toughest drilling climates and access even the most difficult to reach resources.

Naturally, as the quality and durability of the bits increase, so does the price. That’s why used tri cone bits are often a great alternative. Also known as “rebuilt” or “rerun”, they are ideal for undertakings that are smaller in scale and budget. If your next project falls into this category, contact a drill bit service and explore your options. As long as you deal with a reputable supplier, you can rest assured that a used tri cone will meet the same high standards as its newer counterpart.

Good things come in threes: 3 heads; 3 rocks; 3 bits. Of course, these are only a few of the many advantages that you’ll enjoy with the tri cone. A complete list would have too many items to count.

Maybe that’s why, in the mining and well drilling business, the tri cone has been #1 over 2 centuries, and why it will continue to post impressive numbers in the years ahead.

Count on it.
