Best Circular Saw Under £100

The Bosch PKS 55A is the standout corded circular saw under £100. Its 1200W motor delivers consistent power for cutting softwood, hardwood, and sheet materials up to 55mm deep. The aluminium base plate is sturdy and resists warping, ensuring accurate cuts over time. Owner reviews on Amazon and DIY forums consistently praise its reliability and the effective dust extraction port, which connects to a vacuum for cleaner work.

This saw is ideal for DIYers who need a dependable tool for shelving, decking, and framing projects. The included parallel guide helps with rip cuts, and the spindle lock makes blade changes quick. While it lacks a laser guide, the cutting line indicator is clear enough for most users. For the price, the build quality and performance are hard to beat.

The Ryobi R18CS7-0 is the best cordless circular saw under £100, especially if you already own Ryobi ONE+ batteries. It uses an 18V system and cuts up to 48mm deep, suitable for most timber and sheet materials. The saw is lightweight at just 3.2kg, reducing fatigue during longer sessions. Owner reviews highlight its decent runtime with a 4Ah battery and the ease of using it in tight spaces without a cord.

This saw is perfect for DIYers who value portability and already have Ryobi tools. The single bevel adjustment and dust blower help with accuracy, though the dust port is less effective than the Bosch. For occasional use, the performance is solid, but heavy users may prefer a corded option. The lack of a battery in the box keeps the price low, but factor in the cost of a battery if you are new to the ecosystem.

The Einhell TC-CS 860 is the most affordable circular saw in this roundup, often available for under £60. Despite the low price, it offers a 184mm blade and a 55mm cutting depth, matching more expensive models. The 860W motor is adequate for softwood, plywood, and MDF, but it bogs down on thick oak or hardwood. Owner reviews on Amazon note that it is a good starter saw for occasional DIY jobs.

This saw is best for beginners or those on a tight budget who need a saw for basic projects like cutting shelves or fence panels. The plastic base plate is a compromise, as it can flex under pressure, but for light use it performs adequately. The included parallel guide and dust port add value. If you plan to cut hardwood regularly, consider spending more on the Bosch.

The Stanley STSC1825 is a lightweight cordless circular saw that comes as a kit with a battery and charger. Weighing only 2.8kg, it is the lightest saw in this roundup, making it ideal for overhead cutting or tight spaces. The 18V motor cuts up to 45mm deep, which is enough for 2x4 timber and plywood. Owner reviews appreciate the portability and the included battery, which saves extra cost.

This saw is designed for light DIY tasks where weight is a priority. The cut depth limits its use for thicker materials, and the battery life is modest with the included 1.5Ah pack. The plastic base plate is acceptable at this price, but it may affect accuracy over time. For quick cuts around the home, it is a convenient option, but serious users should look at the Ryobi or Bosch.

The Draper 44316 is a corded circular saw with a 1200W motor, matching the Bosch in power. It is designed for rip cutting, with a sturdy aluminium base and a parallel guide that locks securely. The 55mm cut depth handles most timber, and the motor maintains speed under load. Owner reviews on Draper tools note that this saw offers good value for heavy DIY use, especially for cutting long boards.

This saw is heavier than the Bosch at 4.5kg, which can be tiring for overhead work. The dust port is basic and does not connect to a vacuum as effectively. However, for the price, the build quality is solid, and the motor delivers consistent performance. It is a good choice for users who need a powerful saw for ripping and cross-cutting without spending more.
