They fit into the chamfered 20 mm holes of an existing multifunction top and provide precise reference points for expanding the hole grid with the Parf MkII drilling system, allowing new 20 mm holes to be added in exact alignment with the existing grid. Compatible with the Festool MFT\/3 top and all grid tops with chamfered 20 mm holes. Made in Great Britain.

The 3 mm hole in the center of each dog acts as a pilot hole for the 3 mm drill bit of the Parf MkII system, which uses these references to position the guide block in the exact position for drilling new holes at a 96 mm pitch in continuity with the existing grid.\u003c\/p\u003e\n  \u003cp\u003eWithout the re-reamer dogs, adding new holes to an existing grid would require manual remeasurement of positions, with the risk of introducing cumulative errors. The dogs ensure that the new holes are aligned with the original precision of the Parf MkII system.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n  \u003csummary\u003eHow many re-reamer dogs are needed to expand the grid?\u003c\/summary\u003e\n  \u003cp\u003eThe set includes 3 dogs, which is the minimum number to define the positioning of a new row or column of holes using the Pythagorean theorem principle of the Parf MkII system.

Re-reamer dogs are compatible with both versions of the Parf drilling system: MkI and MkII. The 3 mm hole in the center of the dog is sized for the 3 mm pilot drill bit included in both versions of the system.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n  \u003csummary\u003eCan re-reamer dogs also be used to repair damaged holes?\u003c\/summary\u003e\n  \u003cp\u003eYes. If one or more 20 mm holes on the top have been damaged or excessively enlarged due to wear, the re-reamer dogs inserted into adjacent intact holes provide the necessary reference points to redrill the damaged hole in the exact position with the Parf MkII system. The result is a new hole at the original tolerance in the correct grid position.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n  \u003csummary\u003eWhat is the difference between UJK Parf re-reamer dogs and anchor dogs?\u003c\/summary\u003e\n  \u003cp\u003eRe-reamer dogs have a 3 mm central hole for positioning the pilot drill bit of the Parf MkII system. Anchor dogs have an M8 threaded hole for attaching clamps and jigs. Re-reamer dogs are accessories exclusively for expanding and repairing the hole grid; anchor dogs are accessories for clamping and jig construction.\u003c\/p\u003e\n\u003c\/details\u003e","brand":"Ujk","offers":[{"title":"Default Title","offer_id":53015655219528,"sku":"107359","price":21.89,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0891\/2139\/0920\/files\/ujk-cani-revisione-alluminio-3mm-sistema-parf-set-3.webp?v=1777557637","url":"https:\/\/www.krollit.com\/products\/cani-di-revisione-in-alluminio-per-system-parf-ujk-set-da-3","provider":"Krollit","version":"1.0","type":"link"}
