{"product_id":"ujk-tools-router-collet-extension-12mm","title":"UJK Router Collet Extension (12mm)","description":"UJK Router Collet Extension (12mm) addresses a common challenge faced when using routers inverted in a table. Often, even when fully plunged, the collet sits below the table surface, limiting cutting depth. This precision extension utilizes standard ER20 engineering collets that securely grip over a 1mm diameter range without compromising accuracy. It ensures a safer, more stable cut with reduced vibration for improved performance. The collet nut features an ejection ring, allowing for quick and easy cutter changes. Designed to support speeds up to 18,000 RPM, this extension enhances your routing experience. For optimal use, insert the collet extension at least two-thirds of the way in and up to the K line. Always start your router at the slowest speed and test the cutter setup on scrap timber, gradually increasing speed while monitoring for vibration. If any vibration occurs, reduce the router speed to maintain smooth operation.\n\nModel Number: 111749","brand":"UJK Tools","offers":[{"title":"Default Title","offer_id":48013619200163,"sku":"1996643","price":39.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0709\/2469\/7763\/files\/79df974cde39f19181e58ddc6edcafe678d93d9f_1996643_1.png?v=1792739214","url":"https:\/\/www.hartvillehardware.com\/products\/ujk-tools-router-collet-extension-12mm","provider":"Hartville Hardware","version":"1.0","type":"link"}
