Spot weld drill price UK: dated shelves, £7 to £17

Twelve amazon.co.uk spot weld drills, priced on 15 October 2026, run from £7.48 to £16.99. A maker list price is a different figure from that Amazon shelf.
On this page

You are costing a bit, or a small set, before you open a full comparison, and the figures already disagree. A lone cutter sits near £8, a set sits near £17, and Sealey's own page still prints £11.94. The spot weld drill price UK shoppers meet on amazon.co.uk, in this set, is the shelf captured on 15 October 2026: twelve listings from £7.48 to £16.99, in three bands.
A £7 bit and a £17 set are different tools, and a maker list is a different figure from the Amazon shelf. Trade kits at £36.45 and £41.99 sit outside the twelve.
The Products Compared editorial team used those amazon.co.uk listings, plus public prices from Sealey, Frost, and Basic Welding. We did not run a lab test. Twelve shelves are one comparison, not a measure of the UK market. If you buy through a link on the comparison, a qualifying purchase can earn us a commission at no extra cost to you.
In short
On 15 October 2026 those twelve amazon.co.uk listings ran from £7.48 to £16.99. The recorded Sealey AK4734 was £7.99 on that extract, against a maker list of £11.94. Frost at £41.99, Basic Welding at £36.45, and Sealey's carbide boron bit at £47.94 sit outside the twelve.
Spot weld drill price UK on three shelves
You can cost an entry bit, a middle listing, or the top of this set without treating twelve rows as every seller in Britain. A live amazon.co.uk page can leave its band. If it has, rewrite the budget before you order.
The entry cluster, about £7.48 to £7.99, is where cheap spot weld bits sit in this snapshot. The named row is the Sealey AK4734, ASIN B001SG1USG, at £7.99 with 4.6 from 192 reviews. A later snippet showed £8.61, so the basket moved after the raw extract. Measured against its own £11.94 list, and against a set near £17 you may not need, that named 8 mm bit is the best value in this snapshot. The £7.48 floor is cheaper, and this article does not name that listing.
The middle cluster is about £10.99 to £13.50. A few pounds clear of the entry band matters when you are buying one cutter for one panel and you still do not know whether a second size is required. The upper end is £16.92 to £16.99. Dearer, in this table, means a higher shelf on that date. It does not record a longer edge or a safer choice on high-strength steel. The rows sit together on the spot weld drill comparison.
Maker list prices beside the Amazon shelf
Sealey's page for the AK4734 lists an 8 mm HSS cobalt spot weld drill bit at £11.94. On this check the page was out of stock, and it does not place that list next to an Amazon shelf. The amazon.co.uk price is £7.99 in the raw extract, and a later snippet showed £8.61. The gap is on the page. A printed reason is not. A promotion, a different stock position, or two shops updating on different days would look the same from here, so this article leaves the cause unset.
Put £11.94 against £7.99, and keep £8.61 in the same note. A list price with no basket is a reference. It was not a checkout you could finish on the maker site that day.
Two trade kits sit above the Amazon set, and neither is one of these twelve listings. Frost's two-piece spot weld removal set is £41.99, including an automatic centre punch. The punch is why that spot weld cutter set price is a different offer from a lone £7.99 bit. Basic Welding's Laser 7048 is £36.45 for a 9.5 mm crown kit plus an 8 mm cobalt bit.
Leave the subtraction alone. Taking £7.99 from £41.99 and calling the result a saving compares one recorded bit with a set that includes a punch. Match the cutter to the weld on the spot weld drill buying guide once you know which shelf you are on.
What an 8 mm spot weld drill price buys
An 8 mm spot weld drill price, in these sources, is three purchases that share a diameter: the Sealey AK4734 as one HSS cobalt bit, Basic Welding's Laser 7048 at £36.45 with an 8 mm cobalt bit beside a 9.5 mm crown, and the AK4740 at a £47.94 list.
Inside the Amazon set the money pays for one bit, for crowns, or for hole saws. A set at £16.92 to £16.99 can be either. Piece count totals the items in the title. Cutter count totals the edges that cut the weld. A case, a pilot, a mandrel, or a spare can each add one to the number on the box. This snapshot does not itemise a 13-piece listing, so read the contents before you pay the upper band for the number alone.
These prices carry no counted number of welds per bit. A score of 4.6 from 192 reviews is a listing fact, not a cutting test. A cheap spot weld bit at £7.48 to £7.99 can be the right spend for a first panel, and a poor one when you already know you will open several sizes. How the cutter should meet the metal is on how to use a spot weld drill.
Where a boron bit sits on price
A boron-capable bit sits outside the £7.48 to £16.99 set. Sealey lists the AK4740, a solid carbide 8 mm spot weld drill bit, at £47.94, and that page is the carbide boron bit. Set that £47.94 list beside the recorded AK4734 at £7.99 and the dearest Amazon row at £16.99. Only the AK4740 is the carbide boron tool.
Budget the AK4740 when the repair method calls for that bit. Reaching £16.99 does not put a carbide boron cutter in the chuck. If the panel is a sill, a pillar, or steel the method treats as high-strength, the price of a hobby bit is the wrong figure to settle. Spot welds on car panels separates that joint from a wing you are willing to practise on.
£47.94 is Sealey's list price. It is not a row among the twelve, and this page has no recorded Amazon shelf for the AK4740. If you need a basket price, read the live listing on the day you buy, and keep £47.94 in the budget as a named list figure until you do.
Why the shelf price needs a date
A price without a date is a number you cannot audit. These bands belong to 15 October 2026, and the maker and trade pages were checked with them. Next month's basket is a fresh look.
If you write "about £8" on a job sheet, say whether you mean the £7.99 extract or the £8.61 snippet. If you write "about £12", you may be quoting the £11.94 list for a bit that was out of stock on the maker page, or a middle-band listing that was never that Sealey.
Run a short check before you pay.
- Write the date and the band: entry about £7.48 to £7.99, middle about £10.99 to £13.50, or the top of this set at £16.92 to £16.99.
- Name the box: one 8 mm bit, a set whose contents you have read, Frost at £41.99, Basic Welding at £36.45, or the AK4740 at a £47.94 list.
- Open the live amazon.co.uk shelf before you pay. A snippet has already moved the recorded Sealey from £7.99 to £8.61.
- Stop when the panel is structural or the method names high-strength steel. A fresh bit near £8 does not put that panel back.
The gap between the £7.99 extract and a £16.99 set is only a few pounds, so a moved shelf can close or widen it on the day. This page is the snapshot. Your basket is the live price.
