Best 315mm table saw blade 30mm: which job it suits

Updated: 22 October 2026

You want one blade for a named job, and the seven amazon.co.uk listings in this set do not share a job. A coarse rip, a 48-tooth combination, a fine crosscut, and a £19.03 disc whose details field says Metal are different purchases. The best 315mm table saw blade 30mm here is the listing whose printed spec and UK reviews match the cut, not the roundest star. Scores use the amazon.co.uk figures saved on 21 October 2026. There was no laboratory cut. A qualifying purchase can earn us a commission at no extra cost to you. The full table is on the [315mm x 30mm circular saw blade comparison](/hub/saw-accessories/315mm-x-30mm-circular-saw-blade).

Top pick for mixed ripping and crosscutting

The top pick is the Trend CSB/31548 at £37.00, with 4.6 from 95 reviews: 48 teeth, a 3.2 mm kerf, a +15° hook, and a 2.2 mm plate field. A UK review describes seven 4 m lengths of 50 mm oak ripped into 25 mm and still withholds a fifth star. One UK review ran it for a day, put the old blade back, and called the cut terrible. Maximum rpm is not on the amazon listing. On 21 October 2026 Trend's shop listed this code at £113.69. Skip it if the manual limits body thickness to 2 mm or less. The tooth trade-off is on the tooth count page.

Coarse rip, and the £19 blade

For rough ripping, the Trend CSB/31524 is £32.70, 4.5 from 70 reviews, 24 teeth, a 3.2 mm kerf, and a +15° hook. UK texts describe reclaimed rafters and about two years on logs and kindling. Best value is the BGS 3957 at £19.03, 4.5 from 279 reviews: 30 teeth, a 2.2 mm plate, a 3.0 mm cutting width, and 4,200 rpm. The details field says Metal and the bullets do not name wood. One UK firewood note is about four months at two hours a week. No UK text in the sample reports a lost tooth. The plate limit is on the saw fit page.

Fine tooth counts with little UK evidence

The Trend CSB/31572 is £76.95 and 5.0 from five reviews: 72 teeth, a 3.2 mm kerf, and a +10° hook. The only UK text says the cut was nice and clean and names neither timber nor saw. Some UK shops print 15° for the same code. Read the plate. Draper 24969, 25782, and 25873 are £27.07, £28.59, and £36.49, with four, nine, and six reviews, and no UK text that describes a cut. None of those amazon rows prints a kerf. Draper's page for 24969 states a 3.2 mm kerf, a 15° rake, and 4,200 rpm. That is the manufacturer page, not the amazon row.

Who should skip a listing

Skip the 48-tooth Trend if the one-day UK rejection matters more than the oak rip, or if the manual will not accept a 2.2 mm body. Skip the 24-tooth Trend when you want a fine crosscut. Skip the BGS blade if you came for a metal cut, if you need a stated hook, or if four months of weekly firewood is too short. Skip the £76.95 Trend if you are paying for the 5.0 rather than a fine label you already need. Skip a Draper row when the kerf must be on the amazon page. Skip the set if the saw is 305 mm or the bore is not 30 mm. The checks before any of these picks are on the buying guide.

Common questions

Which of these seven is the top pick, and for what job?
For mixed ripping and crosscutting, the top pick is the Trend CSB/31548 at £37.00: 48 teeth, a 3.2 mm kerf, a +15° hook, and 4.6 from 95 reviews, including a UK rip of 50 mm oak. It is not the pick for a coarse-only rip, or if the manual limits body thickness to 2 mm or less.
Is the £19 BGS blade the best value, or a metal blade?
It is best value on price and review count: £19.03 and 4.5 from 279 reviews, with 30 teeth, a 3.0 mm kerf, and 4,200 rpm. The details field says Metal and the bullets do not name wood, so it is not a confirmed metal blade. One UK firewood review reports about four months at two hours a week.
Is the 5.0 from five ratings the best blade?
No. The Trend CSB/31572 is 5.0 from five reviews, and the only UK sentence says the cut was nice and clean. That is a thinner sample than 4.6 from 95 on the 48-tooth Trend. The £76.95 price buys a 72-tooth fine label and a +10° hook on the amazon title. It does not buy a large UK record of how the edge lasts.
When is the 24-tooth Trend a better buy than the 48-tooth?
When the work is coarse ripping. UK texts on the CSB/31524 describe reclaimed rafters, pallets, logs, and kindling. It is £32.70 against £37.00, with 4.5 from 70 reviews and the same 3.2 mm kerf class. Choose the 48-tooth blade when one disc has to rip and crosscut.
Should you skip a Draper blade because amazon does not print the kerf?
Skip it if you need the kerf before you order. Draper 24969, 25782, and 25873 name wood and a tooth count, and the amazon rows leave kerf, hook, plate, and rpm blank. Draper's own site fills some of those fields. Using the site figure is fair only if you say it came from Draper, not from the amazon comparison. A star line of 4.6 from four reviews does not replace the missing number.
