Description

Woodpeckers 851 square packs the features of their best-selling 1281 into more compact size. Unlike most squares on the market, the 851 has a one-piece central core which is precisely machined to be within ±.0085° of 90°. On both sides of that central core, Woodpeckers pin precision-machined cheeks flush with the base and 1/4" (6.35mm) back from the inside edge. This forms a shoulder that keeps the square registered to your material without you holding it in place. Whether you're setting up machines, laying out joinery or checking parts as they go together, the 851 square is the one you want for every step of your project.

The metric scales on the 851 are laser engraved to a tolerance of 0.1mm (0.004") total accumulated error over the length of the blade. The outside scale is ideal for setting tooling heights. The inside scale gives you a perfect zero reference from the edge of your stock.

Each square comes with a wall-mountable MDF case to keep your Precision Woodworking Square right in plain sight and always ready to go to work.

Very Square

Conducted all the well known squareness tests and this proved the claim. I liked the fact that it came in a holder to avoid shop damage. Feels and looks like quality. I am pleased with the purchase.

Pricey, but excellent

I've had my eye on one of these for ages, and was getting fed up with supposedly 'true' squares from other brands. Finally took the plunge and I have to say it's superb. Dead accurate, well made and a joy to use. Only problem is I now want more of their tools!

Don't do reviews, but...........

Staggeringly good service, the shipment arrived from Canada at the Wood Workers Workshop warehouse on the Tuesday, went out by post on Wednesday and arrived with my brother in West Wales on Friday morning ! He's really pleased with it, excellent quality at a reasonable price, flip-out stabilizing tab very useful.

Fantastic all round service!

I've never used Wood Workers Workshop before but have been aware of them for a few years. After spending a long time researching router tables I took the plunge and ordered an Incra top, LS Positioner and router lift, complete with the larger AUKTools router motor. Everything arrived the next day and was packaged superbly. The products are really well made and the router is very powerful and quiet compared to my old one. I had one minor issue with the LS Positioner (an Incra issue, not WWW) and it was resolved very quickly at no cost to me. I would highly recommend this company and the quality products that they stock. There is nowhere else selling woodworking equipment of this quality in the UK. I will be back for more! :-)

Woodpeckers Precision Triangle Set
fantastic.

The shipping was very fast from the UK to Italy. all import taxes and duties were included in the price so no problems there. The quality of the products are very impresive, everything fits perfectly together stright out of the box.

Best customer service

This company has the best customer service I can remember receiving. I emailed a query tangentially related to the product and got a comprehensive reply by return. I ordered the product on.a Friday and it was delivered on Saturday. The Incra products are of course excellent quality. Only a shame they use imperial fasteners, but I did find I could run am M6 tap through the 1/4 X 20 hole in the sliding washer with no obvious I'll effect so I could fit a Bristol knob to the sliding extension adjustment.

Great product and great service.

The product is very good, very accurate. The service from Wood Workers was excellent, I was afraid to buy from UK due to custom fees but all went good in this respect. Thank you.
