A Perfectly Engineered Complement To The Parf Guide System

To create the most accurate 20mm worktop, you need the best fitting 20mm dog. That was our design intent when we set out to create the CF-Dogs or "Close Fitting" Dogs. Most 20mm dogs on the market feature a 19.90mm body, which fits well in the Festool MFT/3 but can result in needless play when used with the Parf Guide System or a 20mm worktop made with precision by a CNC router. Instead, our CF-Dogs feature a 19.98mm body providing a near-zero clearance fit when inserted into a 20mm bench dog hole.

A Smart Add-On To The Parf Guide System

The introduction of Peter Parfitt's Parf Guide System (PGS) now provides the everyday woodworker a means to create highly accurate 20mm patterned worktops to near-CNC accuracy. This system relies on a drilling jig that is indexed to the table via two 20mm bench dogs. Because our CF-Dogs fit into this drill guide and indexing holes with near-zero clearance, you will achieve more accurate hole positions compared to using a traditional 20mm bench dog. This is why our DoubleGroove™ CF-Dogs are the perfect add-on for those using the Parf Guide System.

The usefulness of our DoubleGroove™ CF-Dogs is not limited to those using the Parf Guide System. Many woodworkers are creating custom 20mm tops with CNC routers capable of machining holes accurate down to ±0.002” (0.050mm). With this kind of accuracy, many discover that their traditional 20mm bench dogs now fit with too much play; a problem that can be solved with DoubleGroove™ CF-Dogs.

• Easier to Use: Twin grooves running along the collar make DoubleGroove Dogs easier to remove than other dogs on the market; no more stuck dogs!
• A Special Fit: Precision machined to exacting tolerances, with a diameter of 19.98mm to fit snugly in precision-machined 20mm holes.
• Ideal for High Precision Custom Worktops: If you've made your own perforated worktop based on the 20x96mm standard and aren't quite sure if your tolerances are perfect, you'll likely find our general-purpose DoubleGroove Dogs to be a better choice. But if you've made your work surface using a CNC router or a high precision method such as the Parf Guide System, these CF-Dogs should provide a better fit.
• Clampable: Each dog includes an M8x1.25 threaded hole, perfect for use with our SpeedKnobs to secure the dogs inside your 20mm perforated worktop. (If you already have the knobs from Festool's 488030 Clamping Elements, those will work too, but you'll find our SpeedKnobs to be much faster and easier to thread.)
• Material: 6000 series aluminum alloy, T5 tempered and anodized clear
