There are many reasons you may need to drill through carpet, from getting power to a desk in the middle of the room, to running network cables for television or internet. Follow this guide to avoid unsightly snags created by drilling into carpet.

  1. Choose a method below and assemble the appropriate supplies and materials. This includes a cordless or corded handheld drill and an appropriate bit. If the carpet is installed over concrete, you will need a masonry bit. For wooden floors, a regular steel twist bit is sufficient. 
  2. Eye protection is always recommended when using a tool that rotates at high speeds. While drilling is unlikely to produce dangerous projectiles, you only get one set of eyes. The use of extra protection is justified. If drilling into materials that release silica dust, you absolutely must protect your lungs with a respirator. 
  3. Using the method of your choice, prepare your drilling surface. This could include melting the carpet fibers, compressing them, cutting the carpet, or even beginning the hole by hand. 
  4. Attach the drill bit to the drill and tighten the chuck. If you prepared the carpet for drilling by melting the fibers with reverse drilling, make sure you flip the toggle switch to ‘forward’ before starting to drill. 
  5. Holding the drill at a right angle to the floor, squeeze the drill to start the rotation of the bit. A variable speed drill can be operated at low speeds, allowing you to monitor for signs of snagging. Should a thread become caught or wrap around the bit, stop drilling immediately and disentangle it. Use one of the methods below to enlarge the prepared surface. 
  6. When you’ve created a hole of the desired depth and diameter, back the bit out of the hole and clean it using a vacuum or a can of compressed air. Don’t blow into the hole, as you may displace dust or debris into your eyes, face, and lungs. If necessary, clean the edge of the hole with an abrasive material such as sandpaper. 

Methods for Drilling Through Carpet

Many different techniques can be used to prevent carpet fibers from unraveling and wrapping around the point of your drill bit. Any of the methods below will make it easier to drill through carpet, and decrease the likelihood of snags. 

Use Heat

Carpet fiber melts when introduced to high heat, forming a plastic-y barrier that is easier to drill through. You can use a heat gun or soldering iron to melt a small portion of the carpet.

Alternatively, heat the tip of your drill bit with a candle or torch and touch it to the carpet surface. The melted area should be slightly larger than the hole you intend to drill. 

Insert the Screw By Hand

Snagging is more likely to happen when drilling through the carpet at high speeds. Avoid this by starting the hole using just a screw and the rotational force you can generate by hand.

Turn the screw slowly while applying pressure to slowly work it through the carpet and pattern. Once you’ve passed through the carpet backing, enlarge the hole by rotating the screw in a wide circle.

Drill in Reverse

Another way to melt the carpet fibers is to use the friction of your drill to create heat. Instead of drilling into the carpet, flip your drill into reverse mode. Hold the spinning bit against the carpet until the fibers melt. 

Make a Flap In the Carpet

Perhaps the easiest way to avoid snagging is not to drill through carpet at all. Use a utility knife to score the carpet in a U, V, or X shape. Fold the resulting tab back, exposing the material underneath.

After you’ve made the hole or inserted the screw, you can unfold the tab so that it covers your work. You could also use a small piece of copper tubing to hold the flaps out of the way while you drill. 

Compress the Carpet Fibers

A small cylinder of PVC can be pressed firmly into the drill site. While this won’t prevent snags entirely, it should prevent large, cross-carpet thread pulls. 

Use a Carpet Cutter Drill Bit

If you frequently need to drill through carpet, it may be worth it to purchase specialty accessories. Carpet cutter drill bits and guides bore a clean hole through carpet without snagging.

They usually include a drill guide that performs double duty, compressing the carpet and ensuring production of a straight and even hole. Carpet cutters produce a recoverable plug of discarded carpet, which can be replaced if desired.

Use an Awl and Mallet

Specialty tools aren’t always necessary – sometimes it’s better to go back to basics. Tapping gently with a mallet on the handle of an awl should generate sufficient penetrative force to break through your carpet backing and underlayment. You can then drill into the subfloor below

Carpet-Specific Drilling Recommendations

Most carpets are made by attaching long fibers to a plastic backing. This creates loops of fiber on the surface of the carpet. When these loops are cut, the result is called cut pile carpet.

When the loops are not cut, the carpet is more durable and resistant to compression. This kind of carpeting is called Berber or looped carpet. Unfortunately, it’s prone to snags, which can affect large areas of carpet due to the connected loop design. 

Choosing the right method for your carpet will increase your odds of successful, no-snag drilling. 

Drilling Into Berber/Looped Carpet

Scoring the carpet with a utility knife is the best way to prevent snags when drilling into looped carpet. Alternatively, you can melt the carpet fibers, but you may need to make a larger melted area to avoid snags. 

Drilling Into Pile Carpet

Methods that rely on melting or compression of carpet fibers work best for pile carpets. Each tuft of carpet fiber is attached only to the carpet backing, so the potential for large snags is considerably lower. Non-powered methods such as using a screw or an awl will also work well. 


Snagless drilling through carpet is possible with a little foresight and planning. There are multiple methods to choose from. You may need tools like a utility knife, drill guide, or carpet cutting drill bit. Work slowly and carefully to break through the carpet before drilling through the surface underneath.
