Product Description
Two tools in one, for crafting 20mm worktops
The Parf System relies on the fine tolerance fit between the dog holes and the dogs—neither too tight or too loose. Changes in humidity can make it difficult to insert or remove 20mm dogs. Machined from stainless steel, this UJK Combined Chamfer & Reamer Tool does two jobs at once.
This 2-in-1 tool featuring a 10mm hexagonal shank can be used in your favorite cordless drill chuck (use slow speed). The reamer portion has a gentle lead in and four cutting flutes to ream the holes to a precise size. With this woodworking multi-tool, your 20mm dogs will fit snugly without wobble yet can still be removed without difficulty.
After the reamer, the woodworking chamfer tool comes into action. It cuts a neat, shallow chamfer around the top of the dog hole. This chamfer allows full use of our Power-Loc or Smart Connect Bench Connecting Dogs, as well as UJK Parf Super Dogs or any other 20mm dog that utilizes a lip. In addition, by removing the sharp edge around the hole, it prevents damage from repeated insertion of dogs, clamps and other accessories. The chamfer features a solid tungsten carbide cutter with four adjustable cutting sides.
NOTE: This cutter works best in MDF, HDF or plywood with a melamine facing. NOT recommended for hardwood veneer plywood, where the high cutting speed of a traditional woodworking router and chamfer bit with pilot bearing will provide a superior result.

Solid, well built
it is pricey, but it is really well built. And it works as expected. It works better in my opinion if the hole is already a little bit over 20mm. I machined the holes 20.2mm and it works perfectly well. But I also tried it on 20 and it works. VERY handy when after applying the finish to my MDF table, the holes were not exact anymore, I opened them back with this tool and now it works. Really great.

Chamfer reamer
A tool you cannot live without if you have a 20mm bench top. Cleans out glue and debris to get a good dog grip

Essential for maintaining 20mm grids
This combined chamfer and reamer tool is, IMHO, an essential tools for maintaining 20mm grids in worksurfaces, especially when glue, finish and other fluids come into play. Properly sized holes allow for the expected precision when using 20mm dog accessories including snug, but easy insertion and removal. The chamfer that this tool also maintains, helps prevent damage to the top edge of the holes and makes for consistent use of dog products that have the chamfered flange to support them in the holes. It's well made and should last a lifetime, too.

Mixed thoughts
I love the heft of this tool. However, it does slightly enlarge the 20mm hole before reaching the chamfer. This will be useful if glue or finish gets into the holes, otherwise, the hand chamfer tool is better suited for the job.

Documentation missing
Just ordered and received this expensive item. No instructions and no receipt. Even a five dollar purchase on Amazon comes with documentation.

Chamfer & Reamer
Used this for the Bora Centipede 20mm top. Did a very good job correcting the hole size and clean chamfer. Did get hot to touch during use towards the end, but not overly so.
