It features a 3\/16-inch inner diameter and a 5\/8-inch outer diameter, with an overall length of 2-3\/4 inches and a head diameter of 3\/4 inches. Two lock-down screws clamp the boring bar firmly in place, minimizing deflection and maintaining tool position during interrupted cuts or continuous passes. Machinists and toolroom technicians working with small-bore or internal grooving applications rely on this style of holder for consistent, repeatable tool alignment. The compact head geometry fits close-clearance setups where space inside the workpiece bore is limited.\u003c\/p\u003e\u003cp\u003eThis holder is suited for light-duty internal boring and grooving work on manual or CNC lathes. Its Series DH designation places it within a standardized family of bar holders, making it a straightforward drop-in for shops already running that tooling series. It is appropriate for both production environments and job-shop setups where operators need a compact, rigid holder for 3\/16-inch shank boring bars used on small-diameter bores in ferrous and non-ferrous materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/16-inch inner diameter accepts standard 3\/16-inch shank boring bars\u003c\/li\u003e\n\u003cli\u003e5\/8-inch outer diameter with 3\/4-inch head for compact fitment in tight bore clearances\u003c\/li\u003e\n\u003cli\u003e2-3\/4-inch overall length provides reach for typical small-bore internal operations\u003c\/li\u003e\n\u003cli\u003eTwo lock-down screws deliver secure, rigid bar clamping to reduce tool movement under cutting load\u003c\/li\u003e\n\u003cli\u003eSeries DH design for standardized compatibility within that holder family\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 3\/16-inch shank boring bars in Series DH tooling setups on manual and CNC lathes.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before mounting or removing the bar holder. Insert the boring bar to the appropriate depth, then tighten both lock-down screws evenly to secure the bar without distorting the holder bore. Verify tool centerline height and overhang before resuming cutting operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInner Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2-3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Lock-Down Screws\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: DH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.219 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ACC-62-3\/16\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51733139587378,"sku":"ACC-62-3\/16","price":59.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ffc76429fa826b108f57a817383164ae.jpg?v=1788751778","url":"https:\/\/voomisupply.com\/products\/accupro-acc-62-3-16-boring-grooving-bar-holder","provider":"Voomi Supply","version":"1.0","type":"link"}
