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.

Prepares your 20mm holes to accept new flush dogs
This made my MFT the way it should be made, great product!!
My 20mm bench top was a pain to use after excess finish found its way in the dog holes. This tool quickly and easily solved that problem.
I hesitated to buy this. I just got my MFT and I was afraid it would "ream" out my holes and that my dogs would not fit as snug. I have TDS-13 Low Profile Dog Stops and as well as the MTR-X triangle. The dogs that come with those fit perfectly. The chamfer this adds is great. I do recommend getting this.
I thought this would be a good tool to have. I wanted the reamer to be able to use the revision dogs I ordered for the Parf Guide System, as well as other dogs with the beveled ring. I thought the reamer would be a good idea in case glue ever got into the holes. I thought it would just clean out the hole and return it to normal. I just finished making my first mft style table top and used the bevel feature. The reamer enlarged the holes so that my close fit bench dogs are much looser than before. The description should warn potential buyers the reaming action will enlarge the holes beyond 20 mm. I guess I will put the tool in my metal lathe and turn the reamer down so it doesn’t ruin the holes in future tops I’m planning to make.
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.
very specific..must have MFT table or 20mm holes. revived my 15 year old table so I can use my bench dogs again.
A tool you cannot live without if you have a 20mm bench top. Cleans out glue and debris to get a good dog grip
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.
