Description

Designed and intended for use on MDF and HDF material; not recommended for hardwood veneer plywood.

Two Tools in One: Power Reamer & Chamfer

The Parf Guide 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 at 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 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 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. If it ever gets dull, which is unlikely, you can always rotate the carbide insert to another side.

Note: This cutter works best in MDF, HDF or plywood with a melamine facing. We do not recommended it 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.

    UJK camfer & reamer tool

    The results were good. I used it on a Centipede 20mm top and it was fairly hard to drill. I am not sure if they use a harder MDF.

    Simultaneously chamfer the margins and accurately resize dog holess

    Posted by John Gunn on 7th Jan 2026

    Works well in conventional MDF. Does NOT work in the hardened MDF used by BORA to make the 19 mm holes in their Centipede tops. The Bora MDF is so hard that the chamfering tool cannot cut it- instead it just wobbles and burns the walls of the holes leaving irregular oversized holes. I recommend that you DO NOT use this tool on Bora Centipede tops.
