Understanding Metal Drilling

Metal drilling refers to creating holes in metal for multiple purposes, including product assembly, ventilation, etc. Metal drilling is not as straightforward as drilling wood or plastic, as metal is very hard and requires the right skill set to achieve excellence. In addition, understanding the tools at your disposal and the metal you are drilling is crucial for effective drilling.

Metal Drilling Essentials

You need the right tools to achieve the greatest results and excellence in your work. Here is a list of all the metal drilling essentials.


Of course, you need a drilling machine if you are drilling. There are two types of power drills that you can use: hand drills and power drills. Hand drills are manual, and you must rotate them bit by bit to carve a hole. On the other hand, power drills are the most common type of drill, and they are widely used in metal fabrication. They are powered by electricity and are quite easy to carve holes with.

Drill Bits

A drill cannot work without its drill bits. Drill bits are small, pointed tools that are an indispensable part of the drilling machine. When rotated, they scoop off the metal from the sheet. There are different types of drill bits, such as cobalt, stainless steel, HSS, etc.


As the metal is drilled, it generates heat, which can damage the drill bits and the metal itself. Thus, lubricants are used to reduce friction and improve drill quality.


For every metal project, you need a stable, clean, and clutter-free workstation. This will contribute to the stability of the metal piece under operation and allow effective metal drilling. Ensure that your metal workstation is at the right height and can bear the brunt of machines. If you are not investing in multiple tools, you can use a table as your workstation.


Clamps or vises are essential for every metal fabrication technique. They secure the metal workpiece in place and prevent movement during drilling.

Center Punch

A center punch is a tool for creating an indentation in the metal before using the drilling machine.

Deburring Tool

A deburring tool is used to remove any sharp edges or burrs from the drilled hole for a clean finish.

These essential tools must be in your garage before you commence any drilling project. If you need help, call us at New Mexico Metals LLC for expert metal drilling services in Albuquerque.

Selecting the Right Metal Drill Bits

Many DIY enthusiasts claim to have all the right tools but still end up with a messed-up drilling job. The reason might be choosing the wrong drill bit, which makes all the difference in metal drilling operations.

Here are some factors you should consider when choosing a metal drill bit.

Material Compatibility

Is your drill bit compatible with the metal that you are drilling? Understanding metal properties is crucial here. Cobalt or carbide drill bits must be preferred when drilling stainless steel or titanium. You can also use HSS drill bits for multiple metals.

Size and Diameter

You must choose the drill bit based on the desired size and diameter of the hole. Using an oversized or undersized drill will pose challenges.

Point Angle

Drill bits come in different point angles, such as 118 degrees or 135 degrees. Choose one based on metal type and thickness.

Specialized Bits

These drill bit types are used for specific operations such as enlarging existing holes or creating countersinks.
