With a 2.5-inch body diameter and an integral R8 taper shank mount, this tool is built for direct, rigid connection to the spindle without a separate adapter. The overall length of 7-3\/16 inches keeps the tool extension moderate, supporting stable cuts. It is installed and used by machinists and tool-and-die professionals in job shops, maintenance facilities, and production environments.\u003c\/p\u003e\u003cp\u003eThis offset boring head is suited for single-point boring operations on knee mills and vertical machining centers equipped with R8 spindles, which are common in small-to-medium machine shops. The integral taper shank eliminates adapter stacking, reducing runout and improving bore accuracy. Typical applications include opening existing holes to precise diameters, cleaning up rough bores, and finish-boring bearing fits, bushing bores, and housing seats.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2.5-inch body diameter provides a solid platform for extended boring ranges\u003c\/li\u003e\n\u003cli\u003eR8 taper integral shank mount for direct spindle engagement on compatible mills\u003c\/li\u003e\n\u003cli\u003eOffset head type allows fine diameter adjustments for precise bore sizing\u003c\/li\u003e\n\u003cli\u003e7-3\/16-inch overall length balances reach with rigidity\u003c\/li\u003e\n\u003cli\u003eIntegral mount design eliminates adapter stacking and reduces runout\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with milling machines equipped with an R8 taper spindle.

Power down and lock out the machine spindle before inserting or removing the boring head. Secure the R8 shank fully into the spindle with the appropriate drawbar and torque to the machine manufacturer specification. Verify tool runout with a dial indicator before taking any cuts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Offset\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Integral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Taper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTaper Size\u003c\/strong\u003e: R8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7-3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 223-1150\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51712181502258,"sku":"223-1150","price":194.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ae4c52f1c2250e3603ddbf4ad1d24d5b.jpg?v=1788484781","url":"https:\/\/voomisupply.com\/products\/value-collection-223-1150-offset-boring-head-r8-taper","provider":"Voomi Supply","version":"1.0","type":"link"}
