Presenting the PTR-18
An 18" (457mm) precision triangle designed to take advantage of your 20mm perforated worktop
Expanding your woodworking capabilities with the TSO Products PTR-18, the first precision triangle designed to take full advantage of worktops featuring the 20mm hole pattern popularized by the FestoolⓇ MFT/3 MultiFunction Table. Out of the box, the PTR-18 will be the most accurate triangle in your arsenal—but it’s no simple triangle. Careful engineering and smart design features set the PRT-18 apart, making it a great solution for squaring your workpiece on a Festool MFT/3, verifying the accuracy of a custom-made perforated 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 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 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 ball-tip Allen 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 perforated 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: Index the PTR-18 to your Festool MFT/3 table with our DoubleGroove™ Dogs and SpeedKnobs™.
- Warranty: Backed by our lifetime guarantee.

Quickly square your guide rail to the MFT/3 worktop or fence.
Confirm interior squareness of even large cabinet builds.
Remove the foot to calibrate your miter gauge to the table saw blade, or ensure a perfect 45 or 90 degree cut on the miter saw.

This triangle a mft table a 20mm dog and clamp you can cut any angle you want perfectly every time. It's a great addition to my MFT table and shop
excellent tool for squaring up my MFT3 table. great for squaring up cabinet boxes.
The quality of workmanship is outstanding works great setting
fence on Mft3 table.Very easy to read build robust to last forever.Even has imperial or metric scales.I installed the bar to raise it so I could
set my fence parallel.Very satisfied.
This precision tool is perfect for a variety of things. Obviously squaring boxes, but also squaring my MFT guide, squaring my mitre saw, using the long side for a straight edge when coupling track saw guide rails. I also really like the dual scales as I am trying to convert to doing all work with the metric system (easy to use but hard for me to visualize lengths so far). The removable edge is another plus that adds to its versatility. And this tool is solid, probably weighs 4 lbs. Bottom line, it is an expensive PRECISION tool that will last you a lifetime. It's worth the one time wallet pain.
The trangle is manfactured very precise and offers rhe ability to be positioned by 20mm parf dogs to my MFT3 desk. I am now practising for some days only but I like it very much.
There is one major draw back: no distributer in Europe and you have to be aware that import tax has to be paid on top. I hope TSOproducts will come up with some more tools for the engaded woodworker.
