The best cutting in paint brush to get those clean lines

This Dulux Perfect Edges 1-inch Triangle Brush is a great one for cutting in. Its uniquely shaped brush head is designed for precision edging and ensures you get straight, clean lines.

Customers report this brush is great for getting neat, straight edges when painting but some customers found that while it's easy to clean, they had issues with a few of the bristles coming loose after the first use and clean.

Another great cutting-in sash brush is Purdy's Elite Dale 1.5-inch product. With thousands of reviews, it has been designed for a greater paint lift and smoother application. The hand is chiselled for precision cutting in and you're guaranteed no loss of filaments. Ideal for water and solvent-based coatings, it allows for the perfect painting of edges.

Customers appreciate the smooth finish that this brush gives and they also think it's good quality and worth the money. However, opinions are mixed on how much paint the brush holds. Some think it doesn't hold enough paint and others think it holds too much.

The best cutting in paintbrush for precision is Hamilton's Performance 2-inch product. Suitable for all types of paint, the synthetic filament allows for a high-quality application, finish, and durability. Especially for water-based paints. The medium series size also seems to hold more paint than thinner models.

With an average star rating of 4.7 stars out of five, this is a top-rated product on Amazon, with it rating highly for its ergonomic design, and how easy it is to clean and hold. It does struggle to keep its shape after it has been used/cleaned though.

Wooster Brush has created the shortcut angle sash paintbrush, which is extremely popular. With over 9,000 five-star reviews, it has a flexible purple Shergrip handle, giving it great manoeuvrability in tight spaces.

Its wooden handle is shorter compared to others on our list, which some reviewers found it made the brush difficult to work with, but most reviewers have found the shorter handle gave them greater precision and that it was easy to hold, with one even mentioning that it was good for their arthritic hands.

Another Purdy favourite is this Clearcut Series Glide Angular Trim 2.5-inches Paint Brush. Additionally, it also comes with an option for a smaller or bigger-sized brush. With long bristles and a beautiful wooden handle, it's certainly worth the investment and is suitable for all paints.

With hundreds of high ratings, reviewers recommend it for its smooth finish and great quality. It's also recommended by many professional painters. This cutting-in brush ensures you get a neat joint at the ceiling, around doors and skirting boards. Some reviewers think it is a little thin, so doesn't hold a lot of paint.

Harris's Seriously Good Walls and Ceilings Angled Paint Brush is one of the best for cutting in – and it says it all in the name! The two-inch brush has been designed to give you a controlled paint application along edges and into corners. Especially with emulsion paint, you will see some excellent results.

Customers appreciate the quality and overall value of this paintbrush, and many reviews also mention that it has a comfortable handle, so you shouldn't get aching hands during long painting sessions. Opinions are mixed on the bristle loss, some reviewers had issues with shedding, but others say it rarely loses any bristles.

One of the best cutting-in brush sets is the Hamilton Prestige Sash Three Pack. Being Amazon's choice for sash brushes, it's made from synthetic hair, wood, and metal. Not only is the waxed wooden handle a dream to use, but the pointed head shape is also even more impressive for cutting in. It also has a rust-resistant stainless-steel ferrule.

As there are three brushes included in the pack, customers think this brush set is great value for money. Opinions are mixed on the overall quality, as some reviewers had issues with the heads falling off but they’re easily pushed back on.

Axus Décor's Grey Series Pointed Paint Brush Sets also rank highly on our list. The set of four includes a 1.5-inch brush, two 2-inch brushes and two 3-inch brushes. It's ideal for sash windows, architraves, and mouldings. The super-fine tapered and synthetic filaments are designed to achieve a smooth finish with minimal brush marks.

Customers online say these brushes are good for gloss or emulsion paint, and they like that multiple-sized brushes are included in the pack. There’s only a handful of critical reviews as they’re much liked by Amazon customers but one reviewer thought the bristles could be thicker.
