  • Quickly affix the PTR-18 to your 20mm hole patterned worktop to perform a variety of tasks. Here, the PTR-18 is being used as a 45 degree fence for cutting this large workpiece on a Festool MFT/3.
  • Quickly square your MFT/3 guide rail using the PTR-18's large perpendicular faces.
  • Using the long squaring pins that attach to the face of the PTR-18 and using either bench dogs (as shown) or the MFT/3 fence, you can quickly square a guide rail for perfectly straight 90 degree cuts.
  • Here, the PTR-18 is using its long squaring pins to quickly establish a perfect 90 degree angle between the MFT/3 fence and elevated guide rail. Thanks to the long pins, the MFT/3 guide rail can be quickly squared even in its elevated position.

    Keeps All of the Original PTR-18 Innovations

    Expand your woodworking capabilities with the PTR-18 PLUS, part of the first precision woodworking triangle family designed to take full advantage of work surfaces featuring the 20mm hole pattern popularized by the Festool® MFT/3 MultiFunction Table.

    Out of the box, the PTR-18 PLUS will be the most accurate triangle in your arsenal—but it’s no simple triangle. Careful engineering and smart design features set the PTR-18 PLUS apart, making it a great solution for squaring your workpiece on a Festool MFT/3, verifying the accuracy of a custom-made 20x96mm worktop, or traditional triangle duties such as angle setting on your miter saw, marking angles, or ensuring dead-square cuts on sheetgoods. With its removable foot, this precision woodworking triangle literally stands on its own—to verify squareness of a cabinet interior—or to register a quick 45 degree angle against a reference edge. The PTR-18 PLUS is made in the USA from cast aluminum tooling plate on high-precision CNC machining centers and anodized for maximum durability.

    • Guaranteed Accurate: Machined on high-precision CNC machining centers and made from thick precision aluminum tooling plate guaranteed square to within .001” over its 18” length as verified using an automated CMM (Coordinate Measuring Machine).
    • Removable Foot: Enables freestanding use or quick angle measurement off the edge of your table or workpiece. Includes hex wrench and stainless steel socket screws which can be conveniently stowed in tapped holes along the foot when not in use.
    • Accepts 20mm Bench Dogs: Eight 20mm holes are perfectly positioned on 96mm centers to align with the hole pattern on your Festool MFT/3 table or similar 20mm worktop, and accept our DoubleGroove™ Medium Dogs—providing an accurate, repeatable, and adjustable means of rapidly aligning workpieces or ensuring the squareness of your Festool fence and guide rail. (Note that you can also use widely available alternative bench dog brands, but those alternatives may not provide enough depth to accommodate clamping knobs—like our well-regarded M8 SpeedKnobs™—once inserted through the triangle and table.)
    • Dual Dimensioned: Both Imperial or Metric measurement included (one on each side).
    • Easy to Read: Extremely legible, large, laser-engraved marking.

    Expandable with Accessories:

      Use it for a lot of stuff

      Posted by david houchin on 27th Sep 2022

      Didn't know I needed a triangle until I got it. Can be used for squaring up machines, checking if mft table holes are square, cut 45's, check guide rails, square cabinets for glue up, and much more. Would have liked the MTR but not cutting crazy angles all the time.

      Excellent quality. Precision is there with the machining, finish, packing, and all fasteners + edge lip.

      PTR-18 Triangle

      Posted by Steve LaFara on 13th Feb 2021

      This thing is a beast! I was a little hesitant spending this much for what most would say in a fancy speed square, but I can tell you that it’s worth every penny. Much heavier than I expected but the weight makes it super easy to use and builds confidence in its accuracy. I haven’t had a chance to use all of the features yet but will surely appreciate everything that it can do once I build my new MFT table.

      I bought this to use with my track saw and to calibrate my Incra table saw sled. It has been great for both uses.

      New plus ptr

      Posted by JimmyFord on 3rd Sep 2019

      The ptr triangle makes setting up my mft3 very fast and dead square, every time. The new tapped holes and pins make this a MUST HAVE for the mft in my opinion, its the fastest setup tool I’ve come across for it thanks to the pins and attachable foot. Being able to set the mft fence and the rail square to the table in one go quickly is a huge time saver. And the added bonus of being able to use the ptr as a fence for 45° cuts makes this one of the most valuable tools I use. The pins and 20mm holes really set the ptr apart from all other similar products on the market, like the big red squares and triangles I used to use. Its a great product, I’ve been very happy with it, and is now an indispensable part of my workflow.

      Must-have Tool

      Posted by Marty Gabel on 26th Feb 2019

      Extremely useful and accurate for squaring up large items. Imperial and Metric on same triangle is a great feature. My only reservation is the marking method does not appear to be laser etched, so I will reserve judgement on durability of the markings. Comment from TSO: The markings on the Triangle are indeed laser engraved for a lifetime (or more) of use. :)
