How to undercut door lining frame with a multi-tool

Posted 28 Feb 2022

When it comes to installing wood and laminate flooring around door frames, the method you use can either make or break your flooring installation. If you want to achieve a seamless look, undercutting is by far the best method. Undercutting allows the flooring to slip underneath which makes for a clean and professional, look.

A lot of the time people will try to scribe out the wood to try to get it to fit around the door frame. This causes an unpleasant gap between the door frame and flooring. By cutting corners like this, you’ll instantly turn a beautiful flooring into an awful one.

For this reason, SMART have designed the perfect multi-tool accessory that’ll help you achieve the perfect finish around door frames. Look no further than the 63mm Japanese Tooth SMART blade.

What is the SMART Japanese Tooth blade?

The Japanese Tooth blade is designed to cut a range of materials, including wood, timber overlay flooring and plastic. This blade features a 63mm blade that allows for universal cutting up to 42mm deep.

If you don’t own a multi-tool and are looking for a cheaper alternative, a hand saw is another option. Although this is still effective, you’ll achieve far less neater cuts and it’ll be much more time consuming. Particularly when you have several door frames to undercut.

In comparison, the Japanese Tooth blade is the ideal, easiest solution for neat under cuts. Thanks to its large tooth style, this blade offers faster and cleaner cuts than any other standard hand tool.

How to undercut door lining

1. Line the flooring against the door frame

Line your flooring upside down and flat against the door fame. Ideally you want to use off cut flooring to prevent any scratches and damage when making the undercut. If you don’t have an off cut, simply place your flooring upside down.

2. Attach the blade to your multi-tool

When you’re ready to make your cut, attach the Japanese Tooth blade to your multi-tool.

3. Make your cut

With your flooring positioned against the door frame, set the blade flat on the flooring and slide it directly into the door frame. Be sure not to tilt the blade back and forth as is can create an uneven cut. Your off cut is going to wobble around whilst the multi-tool is on. Use your fingers to stabilise the off cut while pressing gently against the saw.
