This holder features a 3\/16 inch (0.1875 inch) inside diameter and a 3\/4 inch (0.7500 inch) outside diameter, with an overall length of 2.8 inches. Built for use with QTSP-series quick change tooling systems, it includes through-coolant capability to direct cutting fluid directly to the cutting zone, improving chip evacuation and tool life during boring and grooving operations. Machinists and CNC operators working with close-tolerance bores and internal grooving applications will find this holder a reliable fit for production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThe QTSP-187-750 is suited for use on CNC lathes and turning centers where quick change tooling systems are employed. Its compact 2.8 inch overall length makes it appropriate for tight clearance setups. The through-coolant feature is particularly useful in deep-bore and grooving scenarios where flood coolant alone does not provide adequate chip control at the cutting edge. This holder is intended for professional machinists and toolroom technicians working in metal-cutting environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eQuick change design for fast, repeatable tool changeovers on the QTSP series system\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant capability directs fluid to the cutting edge for improved chip evacuation\u003c\/li\u003e\n  \u003cli\u003eInside diameter of 3\/16 inches (0.1875 inches) for precise bore bar seating\u003c\/li\u003e\n  \u003cli\u003eOutside diameter of 3\/4 inches (0.7500 inches) for standard machine interface fitment\u003c\/li\u003e\n  \u003cli\u003eCompact overall length of 2.8 inches for use in confined setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with MICRO 100 QTSP-series quick change boring and grooving tooling systems on CNC lathes and turning centers that accept 3\/4 inch outside diameter toolholders.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the turret is in a safe indexed position before mounting or removing tool holders. Verify that the through-coolant passages are clear and properly aligned with the machine coolant supply before beginning a cut. Follow the machine tool manufacturer torque and clamping guidelines for the quick change system in use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: QTSP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.19 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112809\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MICRO 100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: QTSP-187-750\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MICRO 100","offers":[{"title":"Default Title","offer_id":52057316917554,"sku":"QTSP-187-750","price":295.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e4874c80c92972b0173499a0c77e63be.jpg?v=1790038813","url":"https:\/\/voomisupply.com\/products\/micro-100-qtsp-187-750-boring-grooving-bar-holder","provider":"Voomi Supply","version":"1.0","type":"link"}
