The number that decides whether a blade fits your saw is not the diameter, it is the hole in the middle. Our 110 mm wood blades have a 20 mm hole, the 115 mm have 22.2 mm, and every 185 mm and 235 mm blade we list has a 30 mm hole, so a blade that is the right diameter can still be the wrong blade.
This page is about matching a blade to a saw and picking the right saw for a material. If you are deciding between a circular saw and a jigsaw in the first place, our guide to choosing power tools compares those two directly and this page does not repeat it.
Which blade fits which saw?
Read the hole size off your old blade, or off the spindle on the saw, before you buy. The figures below are read from the variant names and specification fields of the blades themselves.
| Blade | Teeth | Centre hole | Price |
|---|---|---|---|
| 110 mm (4-3/8 in) wood | 40 | 20 mm | 1.500 KD |
| 115 mm (4-1/2 in) wood | 40 | 22.2 mm | 1.500 KD |
| 115 mm (4-1/2 in) wood, with a 16 mm reduction ring | 40 | 22.2 mm | 0.950 KD |
| 185 mm (7-1/4 in) wood, coarse | 24 | 30 mm | 0.850 KD |
| 185 mm (7-1/4 in) wood, fine | 40 | 30 mm | 1.750 KD |
| 235 mm (9-1/4 in) wood, with 16 mm and 25.4 mm reduction rings | 60 | 30 mm | 2.500 KD |
| 235 mm (9 in), specification says suitable for aluminium | 60 | 30 mm | 4.000 KD |
Two things fall out of that table. First, the hole grows with the diameter: 20 mm at 110 mm, 22.2 mm at 115 mm, 30 mm from 185 mm upward. Second, price follows the tooth count, not the size: the 185 mm 24-tooth blade is 0.850 KD and the 110 mm 40-tooth blade is 1.500 KD, so the bigger blade is the cheaper one. Fewer teeth cut faster and rougher; more teeth cut slower and cleaner.
What a reduction ring does, and what it cannot do
A reduction ring is a collar that sits in the blade's hole and makes that hole smaller. The 115 mm blade at 0.950 KD ships with a 16 mm ring, and the 235 mm blade at 2.500 KD ships with a 16 mm and a 25.4 mm ring. So a blade can be fitted down to a smaller spindle, and it can never be fitted up to a larger one. If your spindle is bigger than the blade's hole, you need a different blade, not a ring.
One mismatch worth knowing about before you order
The 1400 W circular saw's own specification field states its blade as 185 x 20 mm. Both of the 185 mm wood blades listed above state a 30 mm hole. Those two numbers do not agree, and we are not going to guess which is right for the saw in front of you. Measure the spindle on your own machine, or bring the old blade to the counter at Shuwaikh Plaza, Khalifa Al-Jassim Street, Shuwaikh Industrial, and we will match it against what is on the shelf.
Which saw for which job?
Every figure here is read from the product's own specification field. Prices are the lowest listed option for each product.
| Saw | What it is for | Blade or bar | Stated capacity | From |
|---|---|---|---|---|
| Wallboard saw | Cutting openings in plasterboard by hand | 165 mm | Not stated | 0.750 KD |
| Hand saw | General hand cutting in wood | 500 mm, 7 TPI | Not stated | 1.550 KD |
| Back saw | Record says wood and plastic; a stiffened blade for straight joinery cuts | 300 mm | Not stated | 1.650 KD |
| Jigsaw, 800 W | Curves, cut-outs and openings | 800 to 3100 strokes a minute | Wood 85 mm, aluminium 10 mm, steel 8 mm | 9.000 KD |
| Electric chain saw, 12 in | Branches and firewood | 12 in bar | Not stated | 11.000 KD |
| Circular saw, 1400 W | Long straight cuts in sheets and boards | 185 mm, 4800 rpm | 65 mm at 90 degrees, 45 mm at 45 degrees | 13.750 KD |
| Cordless reciprocating saw, 20 V | Demolition and cutting in awkward places | 28 mm stroke, 0 to 3300 a minute | Wood 50 mm, hard metal 10 mm, pipe 50 mm | 15.500 KD |
| Circular saw, 1750 W, laser guide | The same work with a line to follow | 185 mm, 5300 rpm | 65 mm at 90 degrees, 45 mm at 45 degrees | 18.500 KD |
| Electric chain saw, 16 in, 1800 W | Record says tree trimming, firewood and garden work; states automatic chain lubrication | 16 in bar | Not stated | 21.500 KD |
| Circular saw, 2300 W | Deeper cuts than a 185 mm machine will reach | 235 mm | Not stated | 22.400 KD |
| Mitre saw, 2000 W | Repeated angled cross-cuts on a bench | 254 mm, 5000 r/min | Not stated | 37.000 KD |
Four of these eleven publish a cutting capacity: the two 185 mm circular saws, at 65 mm and 45 mm, the jigsaw and the reciprocating saw. The other seven state no maximum material thickness at all, including both chain saws, the 2300 W machine and the mitre saw. If the thickness you need to cut is the deciding factor, ask before you buy rather than inferring it from the blade size.
The mitre saw takes 254 mm, and we stock 250 mm and 255 mm
This is the kind of near-miss that wastes a trip. The 2000 W mitre saw states a 254 mm blade. A plain circular blade is 1.000 KD at 110 mm, 3.350 KD at 255 mm and 5.300 KD at 305 mm, with a separate 230 mm listing at 1.750 KD, and the large-diameter range runs from 230 mm with 48 teeth at 13.000 KD up to 400 mm with 120 teeth at 37.000 KD, in centre holes of 30, 32, 35 and 50 mm. Neither range lists a 254 mm blade. Bring the machine's figure with you and we will tell you what is actually on the shelf.
Cutting a round hole: hole saws
A hole saw goes in a drill, not in a saw, and it is how you make a round opening for a pipe, a downlight or a socket. Two ranges, both with prices that rise in order with the diameter.
The bi-metal range states a 38 mm cutting depth, HSS M3 construction and 4 to 6 teeth per inch: 20 mm and 25 mm at 0.750 KD, 32 mm and 35 mm at 0.850 KD, 38 mm at 1.000 KD, 54 mm and 57 mm at 1.250 KD, 60 mm and 64 mm at 1.500 KD, 70 mm and 76 mm at 1.750 KD, 83 mm and 86 mm at 2.000 KD, 95 mm at 2.250 KD, 102 mm and 114 mm at 2.500 KD, and 140 mm at 3.000 KD. The TCT range is shorter and dearer per size: 22 mm at 1.500 KD, 25 mm at 1.750 KD, 28 mm at 2.000 KD, 32 mm at 2.250 KD and 35 mm at 2.500 KD.

Cutting in a Kuwait flat
A 2300 W circular saw on a 220 V supply and a mitre saw on a balcony are two different conversations with your neighbours. For a one-off job in an apartment, the hand saw at 1.550 KD and the wallboard saw at 0.750 KD do more than people expect and make no noise worth complaining about. Timber cut to length at the counter is often the better answer than buying a machine for one shelf. Where the cut is into a wall, a ceiling or anything structural, that is a job for the contractor doing the work, not for a first saw.
FAQs
Which blade fits my circular saw?
Match the centre hole first, then the diameter. Our 110 mm blades have a 20 mm hole, the 115 mm have 22.2 mm, and the 185 mm and 235 mm blades have 30 mm. Two of the blades listed here ship with reduction rings, which make the hole smaller but never larger.
What is an electric saw for wood, and which one should I start with?
For straight cuts in boards and sheets, a circular saw: 1400 W at 13.750 KD or 1750 W with a laser guide at 18.500 KD. For curves and cut-outs, the 800 W jigsaw at 9.000 KD, which states 85 mm in wood.
How deep will a circular saw cut?
Both 185 mm machines here state 65 mm at 90 degrees and 45 mm at 45 degrees. The 235 mm and 2300 W machine states no depth figure, so do not assume a number for it.
Which saw cuts metal?
Of the machines listed, the 800 W jigsaw states 8 mm in steel and 10 mm in aluminium, and the 20 V reciprocating saw states 10 mm in hard metal and 50 mm pipe. One 235 mm blade's specification says it is suitable for aluminium.
How little can a saw blade cost?
A 12 in, 300 mm, 24-tooth hand-saw blade is 0.050 KD, sold two to a set. Circular blades start at 1.000 KD for 110 mm.
How many teeth do I need?
The blades here run from 24 to 120 teeth. Fewer teeth cut faster and leave a rougher edge; more teeth cut slower and leave a cleaner one. The 185 mm pair makes the trade visible: 24 teeth at 0.850 KD or 40 teeth at 1.750 KD, same diameter, same hole.
Bring your old blade or your machine's figures to the counter, or contact us with the diameter and the centre hole and we will tell you what matches.
