The DeWalt D23700 is a big mains circular saw built around a 235 mm blade. That blade size is the whole point: it gives an 86 mm depth of cut, enough to go through railway sleepers, thick fence posts and heavy joists in a single pass. It suits landscapers, framers and anyone building decks and garden structures from chunky timber, rather than people trimming sheet material.

In its favour
- The listing gives an 86 mm depth of cut, the deepest of any saw here.
- A 1,750 W input motor and 4,700 rpm no load speed are stated.
- Bevel capacity of 45 degrees is listed for angled cuts.
Good to know
- At 8.2 kg it is much heavier than the 190 mm saws and tiring for overhead work.
- Only a blade and spanner are listed, with no case or parallel guide.
Our take
What the listing tells you
DeWalt gives a power input of 1,750 watts and an output of 960 watts, with a no load speed of 4,700 rpm. The base tilts to 45 degrees for bevel cuts. The saw ships with a 24 tooth precision blade and a blade spanner, and the model number on the listing is the UK D23700-GB.
There is no mention of a case, a parallel guide or a dust bag, so plan on buying a guide or using a clamped straight edge if you rip long boards.
Why depth of cut matters here
A 190 mm saw stops somewhere around 65 to 70 mm, which leaves a sleeper or a 100 mm post needing a second cut from the other side. That means flipping the piece, lining up the kerf and accepting a small step in the middle. With 86 mm on tap, the D23700 handles most of those jobs in one pass, which is quicker and gives a cleaner end.
The 24 tooth blade is a sensible general purpose choice for construction timber. For neat cross cuts in finished boards a higher tooth count blade would be worth adding.
Weight and handling
The listing puts the saw at 8.2 kg. That is roughly double the Makita HS7611K and noticeably more than the Bosch GKS 190 at 4.76 kg. On a pair of trestles that weight helps the saw track steadily, but it becomes tiring if you are cutting rafters in place or working above waist height. Think about where most of your cuts will happen before choosing it.
How it sits against the 190 mm saws
The Bosch GKS 190 is the better all rounder for sheet goods and stud work, with a parallel guide and dust adaptor in the box. The Makita HS7101J adds an electric brake and LED light in a Makpac. Neither can match the D23700 for depth, so the question is simply how often you cut material thicker than 70 mm.
Verdict
Choose the D23700 if you regularly cut sleepers, posts or deep joists and want to finish them in one pass. If most of your work is plywood, OSB and studwork, the lighter Bosch GKS 190 or Makita HS7101J will be easier to live with and come with more accessories.
