The QTJSZXXT 2-piece Forstner drill bit extension kit adds substantial reach to standard Forstner bits, enabling longer, flatter-bottom holes and smoother starts in deeper workpieces. With separate extensions that add 3-1\/4 inches or 5-3\/4 inches of reach, you can tailor your setup to the project at hand. The total assembly lengths are 4.5 inches and 7 inches, offering practical choices for furniture components, decorative boxes, planters, and other wooden pieces. Two set screws and a compact hex key are included to help secure the shank and maintain control during drilling.\u003c\/p\u003e\u003cp\u003eDesigned for real-world use in busy workshops, this kit emphasizes balance between value, rigidity, and ease of use. It is crafted to extend your tool kit without requiring you to invest in longer, specialized bits. The result is a straightforward way to tackle deeper pockets, through-holes, or start holes in a controlled, repeatable manner while keeping the workflow clean and organized.\u003c\/p\u003e\u003ch3\u003eWhat you get\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e1 x 3-1\/4 inch extension; 1 x 5-3\/4 inch extension; two set screws; hex key for secure mounting\u003c\/li\u003e\n\u003cli\u003eHex shank diameter 3\/8 inch; total lengths 4.5 inches and 7 inches; extension depths 3-1\/4 inches and 5-3\/4 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eBuild quality and fit\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eRugged high-carbon steel construction for durability in daily use\u003c\/li\u003e\n\u003cli\u003ePrecision ground and polished surfaces to minimize wobble and improve alignment\u003c\/li\u003e\n\u003cli\u003eNote: inside diameter of the extension collet is 3\/8 inch, so it fits Forstner bits with 3\/8 inch or smaller shanks; tighten the screws before use to prevent slipping at high speeds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003ePractical use cases\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eDrill flat-bottom holes or start deep holes in larger vessels, vases, boxes, and containers\u003c\/li\u003e\n\u003cli\u003eIdeal for furniture components, decorative woodworking, or storage solutions where depth matters\u003c\/li\u003e\n\u003cli\u003eEnhances reach for tight or recessed areas without changing your standard bit set\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTips for best results\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eSecure the bit with the included hex key before operation\u003c\/li\u003e\n\u003cli\u003eVerify shank size is 3\/8 inch or smaller for compatibility\u003c\/li\u003e\n\u003cli\u003eUse steady, moderate feeds to minimize chatter and maximize control\u003c\/li\u003e\n\u003cli\u003eClamp the workpiece when possible to improve stability during deep drilling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCare and maintenance\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eWipe clean after use and keep dry to prevent rust\u003c\/li\u003e\n\u003cli\u003eLightly oil when storing to preserve surface finish\u003c\/li\u003e\n\u003cli\u003eInspect screws regularly and re-tighten if needed before subsequent projects\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhy choose QTJSZXXT\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eValue-driven kit with two practical extension depths in one package\u003c\/li\u003e\n\u003cli\u003eSimple installation with included screws and hex key\u003c\/li\u003e\n\u003cli\u003eDurable construction designed for repeated drilling tasks in wood\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What tasks are best suited for these extensions?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: They extend Forstner bits to reach deeper or flat-bottom holes in wood projects.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What should I check before using the extensions?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Verify shank size is 3\/8 inch or smaller; tighten the set screws before operation to prevent slipping.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"QTJSZXXT","offers":[{"title":"Default Title","offer_id":47462866616494,"sku":"B0FW54GR1G","price":59.16,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0735\/6012\/9710\/files\/qtjszxxxt-forstner-extension-4-5-inch.jpg?v=1770269497","url":"https:\/\/handyskook.ca\/products\/qtjszxxt-2-piece-forstner-drill-bit-extension-kit-4-5-in-7-in-reach-3-8-in-shank","provider":"HandySkook","version":"1.0","type":"link"}
