Designed to work with UNF threads, this 1-1\/2\" diameter, 12 TPI tap is specifically engineered to be “oversized for wire thread inserts,” ensuring clean engagement and optimal alignment when installing Helicoil-style inserts. This isn’t a generic tap—it's crafted to pair with the wire thread insert system for durable, repeatable results. \u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0560\/3747\/4382\/files\/BEAR_LOGO.png?v=1698662740\"\u003e\u003c\/p\u003e\n\u003cp\u003eWhat makes this bottoming tap stand out is its bottoming design, which reaches the full thread depth required for reliable insert performance in both repair and reinforcement scenarios. When you’re restoring damaged threads or preparing a hole for a critical fastener, a bottoming tap finishes threads all the way to the bottom of the hole, delivering the full engagement length your Helicoil insert demands. This is especially important for high-load applications where thread integrity matters. \u003c\/p\u003e\n\u003cp\u003eKey specifications at a glance:\u003c\/p\u003e\n\u003cul\u003e \u003cli\u003eThread format: UNF (Unified Fine) 1-1\/2\" diameter, 12 threads per inch (1.5\" x 12 UNF)\u003c\/li\u003e \u003cli\u003eFunction: bottoming tap designed to finish threads to the full depth for inserts\u003c\/li\u003e \u003cli\u003eMaterial and build: engineered for durability to withstand repeated use in metalworking environments\u003c\/li\u003e \u003cli\u003ePurpose: compatible with wire thread insert systems (Helicoil) to repair or reinforce threaded holes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eWho benefits from the Baer Heli Coil Tap? This tap is ideal for automotive, industrial machinery, and maintenance work where damaged, stripped, or worn threads need a reliable rebuild. It’s particularly valuable when you’re installing Helicoil inserts to restore strength in aluminum, steel, or cast components, ensuring that the repaired threads can handle the same or higher loads as the original. Rather than replacing entire components, you can preserve critical parts with durable, clean threads that resist pull-out and wear. \u003c\/p\u003e\n\u003cp\u003ePractical usage tips for best results: align carefully with the insert you’re using, apply steady, even pressure, and maintain a consistent cutting speed to reduce chatter and ensure true thread formation. Because bottoming taps are designed to reach the hole bottom, ensure your workpiece has adequate depth to accommodate the full thread length. When in doubt, pair this tap with compatible Helicoil inserts and follow the insert system’s installation guidelines for optimal performance. \u003c\/p\u003e\n\u003c\/div\u003e","brand":"BAER","offers":[{"title":"Default Title","offer_id":41762677948494,"sku":"BAER-B3169","price":214.46,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0560\/3747\/4382\/files\/BAER-B3001-1_9a39ce16-de4b-4e06-984d-f5a0c34f214f.png?v=1724835764","url":"https:\/\/www.protool-ltd.co.uk\/products\/baer-b3169","provider":"Protool Precision Tools","version":"1.0","type":"link"}
