Holemaking - Deep Hole Drilling Tools

Deep hole drilling tools are important when it comes to hole making. After all, a drilling machine cannot complete its job without having the tools. Depending on what process you want to use, you will have to select the right drilling tool. There are many different types of tools. As a result, it can make it difficult to choose. So, let’s go over some tool types!

Hole Making – Solid Drilling

Solid drilling is a common tool that is used within the industry. While it is not the oldest, it is popular because of the variety of sizes that this drilling tool comes in. Solid drilling tools provide great solutions when it comes to the drilling process. Some of these benefits include lower cost per hole, consistent performance, and excellent chip control. This allows solid drilling to be useful in industries such as:

  • Oil and Gas
  • Aerospace
  • Heat Exchangers
  • Tube Producers
  • Automobile
  • Armament
  • Cylinder Manufactures
  • Ship Building
  • Drill Job Shops

Gun Drilling

Gun drilling is considered one of the oldest and widely used methods for deep hole drilling. In fact, this type of tool is used by industries today. This drill is typically a one-piece assembly with a hollow cylindrical drill driver. It’s brazened with a V-shaped crimped tool and assembled with a brazed-on solid carbide drill head. Both of these are connected to a kidney-shaped cross-section.

The gun drill tool is typically found on single-use drill machines as well as on a variety of machining. This makes the gun drilling tool incredibly accessible to different drilling machines.

Counter Boring

Counter boring drilling tools can bore depths 7+ times diameter. As a result, the tool is used to open up existing holes with increases in precision, productivity, and versatility. Counter boring produces holes closer tolerances and finer surfaces finishes. Due to this, it eliminates the need for honing. Counter boring drilling tools come in different versions; push and pull. Though push style should be the first choice when it comes to opening up a hole.


Trepanning is useful when meeting special and specific needs. This tool makes a specific core size. The basic principle of trepanning is to make a core that can be used in other parts, unlike drilling. Also, this is a great alternative if you don’t have sufficient horsepower to push solid drilling tools.
