Description

INCRA's Precision Marking Rule offers unparalleled accuracy, having patented marking holes to mark in rather than just etched graduations, these Rules allow you to mark out precisely with no risk of error.

Just select the slot or hole, insert a 0.5mm mechanical pencil, and mark the measurement with complete accuracy - unmatched in the industry of Marking Rules!

One of the fundamental errors woodworkers make when measuring out is marking a line then marking the next measurement line from the first; compound errors soon build up - these Rules leave those kind of mistakes as a thing of the past.

Features

INCRA'S Micro-fine patented marking holes at every 1mm whilst the four centre rows of holes are at 0.25mm increments along its entire length
Draw a short line at any mm spacing using the outside slots or by selecting the centre rows and twisting your mechanical pencil you can spot mark any measurement to 0.25mm, 0.5mm, 0.75mm or 1.0mm; this gives these rules the best accuracy you can achieve when marking out.

Also available in 300mm, 6" and 12" versions plus 10"/250mm Dual Scale.

Precision Marking Rules are also available in INCRA Rule Sets - 300mm.

Expert Advice on All Our Products

Selected by Woodworkers, for Woodworkers

Best ruler I've used for woodworking

This is a well thought out ruler. Not only do the cut-outs make marking accurately a breeze, the thin metal seems to stick to the wood so no slipping about while measuring and marking. Not sure if this is due to the extra width, the cut-outs adding friction or the floppyness of the thin metal, but who cares because this really is the easiest ruler to mark and measure awkward wood bits. Its also a great price for the features. Will be adding more Incra rules to my collection shortly!

Clever little gadget

Physically surprisingly flimsy but should serve well if protected from damage. A very simple yet clever way to make accurate measurements right down to the millimetre

A superb measuring tool!

For truly precise measurements, those that you need to do when marking out using a magnifying glass to see that it's right, this tool is the bees knees!

Accurate measuring

Excellent product. If you need to measure accurately, and who doesn’t this is the kit to use.
Excellent service from Wood Workers.

One of the best rules for joinery & fine furniture

I wanted another Incra rule, because I bought the 150mm version quite some time ago and loved it. So, as that was such a good purchase, I decided to get the 300mm version to compliment it (including buying the fantastic Narex Richter 25mm chisel).

Incra rules are very flexible though, so if you need something more rigid, this may not be for you, but if you want an accurate rule with an ability to make marks on your components at any point with the provided 0.25, 0.5, 07.5 and 1.0 holes, then this is the one to go for. I’d highly recommend getting a good mechanical pencil too.

The previous purchase of the Incra 150mm rule came as a package from Wood Workers Workshop, which included a 90 degree edge rule, a T-shaped rule (which is really very good) and a mechanical pencil. All but the pencil are fantastic. Unfortunately, the pencil fell apart the first time I used it, so I’d recommend a brand like Faber-Castell instead. You can use a normal pencil - well, sort of, but a mechanical pencil works best - and you’ll get the most out of the Incra rule if you do. All in all, I’d highly recommend the Incra rules; they are well made, super accurate and far more helpful than you may think. If you can afford the 150mm kit too, I’d get that, because it’ll cover a lot of eventualities.

With regard to Wood Workers Workshop , and as my review of the Narex Richter 25mm chisel mentioned too, they have always been great, with speedy delivery and they always keep you up to date. Buy with confidence.

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! :-)

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.
