Designed to pair with standard jig-borers and milling machines, the R4e-5-1 relies on common mounting interfaces and adapters to secure the head and maintain alignment during operation. Operators adjust the bore diameter in controlled increments to reach the desired size, enabling repeatable hole sizes across multiple passes with reduced runout. The broad 2-12 inch range makes it suitable for workpieces that require oversized holes or for fixtures where precise hole sizing is critical to assembly tolerances. The model emphasizes stability and repeatability, featuring a robust clamping arrangement and a rigid body design that supports accurate hole geometry under cutting loads. This SIP Societe boring head is a specialized accessory for metalworking setups where accurate, large-diameter bores are required, helping machinists achieve consistent results in demanding applications.\u003c\/p\u003e\u003c\/div\u003e","brand":"Sip","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46267966193898,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-016.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/industrial-r4e-5-1-boring-head","provider":"GTG Hardware","version":"1.0","type":"link"}
