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 chamfer 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.

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.
I was a little skeptical about this tool as I had heard people say that it gets very hot. Nonetheless, I have one now and didn't experience the heating up. I ran the drill on a slow speed setting as per the instructions, kept the drill plumb and away I went, hole after hole. Very useful if you live in a humid climate and fibres in your dog holes swell. I did a quick video to show it in use if you want to have a look. https://youtu.be/A2VFE0_UH98
I chose this tool to go along with my Guide System Mark II, instead of buying the separate the chamfer-only hand tool. I figured I'd need the reamer someday. The quality is outstanding. The reamer does make the holes slightly bigger than the 20mm bit that came with the Mark II. However, both Axminster and TSO dogs still have zero play, and the TSO CF dogs are now much easier to remove. The chamfer the tool makes is also perfect. Overall, I highly recommended this tool.
