Drilling Holes In Car Bodywork

How To Drill Holes In Car Bodywork at Home?

Drilling two or more openings in the automobile body is required to install accessories such as an antenna, side mirror, or tow strap.

However, it is not challenging, and blunders are costly. For example, a power drill slip may do significant harm to paintwork in a couple of moments. Before buying a power drill, don’t forget to take a look at this Milwaykee 2767 vs 2763 model comparison.

Once you take up a tool, think about what you’re going to accomplish and how you intend to do it.

Avoid drilling a hole without thinking about underneath it to prevent issues such as penetrating the radiator when installing a grill plate, the gas tank when installing a reverse light, or producing a short circuit when installing an additional gauge.

Most holes can be drilled using a power drill and an appropriate bit. To begin, generally use a little bit to create a pilot hole. Power-drill accessories such as cone-shaped grinds and blades are available for bigger holes.

Metal blades and hammers are generally available for hire from specialized companies. Keep in mind you have a supply of extra blades when blades are installed.

Drilling Holes

A car’s bodywork is curvy and sleek, and it scratches readily. So put broad sticky tape over the area to be drilled to keep the marking instrument or drill from moving off track.

Thoroughly select, examine and gently mark the exact location using a pencil. Next, make a minor depression in the metal with a hammer and a sharp center punch.

Mark the metal with a center punch to prepare it for drilling holes. Create only a slight depression.

Adjust your power drill’s speed control to a high setting if it has one. Next, drill a small hole through the drawn mark with a tiny bit no more significant than in. (3mm). The pilot hole will serve as a hub for a more significant bit.

Drill the hole to the appropriate dimensions using a sequence of bigger bits. In general, every bit size should not be any larger than double the size of the one preceding it.

Large openings are nibbled.

A nibbler, also known as a sheet-metal grinder, is used to remove vast amounts of metal, such as when drilling holes in the walls of a van.

Outline the aperture. Drilling holes in a tin. (6 mm) hole at any position immediately on the inside of the opening outline using the procedure specified.

In the hole, slide the nibbler blade. When you press the nibbler levers, the razor creates a 3/32 in. (2 mm) broad groove. Each push moves the slot closer to lin (6 mm).

The blades are really hard. However, it can quickly shatter while maneuvering around an edge. So make absolutely sure you have extra blades on hand.

Making use of a tank cutter

To drill an antenna or wing light hole, attach a tiny tank cutting tool with a movable blade to a carpenter’s hand brace.

It is not the most convenient approach to create a hole in a car body, and it may be less precise for bigger hole sizes.

A tank cutter’s blade may be changed to fit the size of the hole. Then, it rotates around the power drill to cut a metal circle, making it easy for you to rotate the tire.

To begin, drill a test hole in the middle of the cutting circle.

Making use of a round-hole punch

Each external diameter necessitates a separate punch. If the punch blade is exceptionally sharp, the hole borders will curl.

Cover the metal and note the location of the desired hole. Next, drill a hole wide enough to accept the punch bolts using the technique outlined.

Insert one punch half on either side of the subject. To connect these, slide the screw through. To punch the hole, lock the bolt. If its broken, then remove the broken bolt!

Unbolt the bolt and separate the parts from disassembling.

Making use of a tapered grinder

A power drill can be equipped with a cone-shaped pointed grinder or blade. It will produce holes of varying diameters up to their largest size. When used at an inclination, it creates oval holes.

Using the cutter or grinder, enlarge it until it meets the outline mark. Be cautious not to overdo it.

Do not try to force the tool to cut faster. The very thin metal commonly used for automotive wings distorts quickly.

Using a file to enlarge a drilled hole

A hole around 3/4in (19mm) wide is required for most aerials. Drilling a large hole is impractical, but a smaller gap may be widened with a file.

Mask the area and outline the hole. Drill a 10mm hole in the specified format.

Attach five or six strips of masking tape all around the top of a 6mm rat-tail blade. Overlap this at the finish.

If the file unexpectedly slides out of the hole while you’re functioning, the tape will keep it from hurting the paintwork.


Is it necessary to drill holes before painting?

Any chipping or accidental tearout may be simply bonded before actually painting. Corrections are a little more complicated after painting. You won’t see any issues with the holes if you spray.

Is it okay if I simply paint over nail holes?

Repainting a wall would Not conceal nail holes; you must fix nail holes first. This process is simple with the correct equipment, and your completed paint job will seem much more sophisticated.

Is it possible to drill into a towbar?

Drilling the second hole in the base of any tow bar or hook attachment is not permitted. The metal will be weakened if a second hole is drilled. In addition, the shank may break during towing, causing the towed car to split.

Bottom Line

There are several solutions on the marketplace for fixing minor holes, smoothing out a dent and wrinkles in your car’s exterior.

Most packages include at least two components: the filler and a bonding agent that must be mixed before being used.

Thoroughly check at the auto body repair store for the equipment with the most straightforward instructions to accomplish the work as quickly as possible.
