It features a right-hand cutting direction and a bright finish coating with no additional surface treatment that would alter the dimensional tolerances critical at this scale. The minimum bore diameter is 0.035 inches, the maximum bore depth is 0.125 inches, the shank diameter is 0.125 inches, and the overall length is 1.5 inches. This bar is designed for machinists and tooling technicians working on precision components where tight bore tolerances and a rigid, vibration-resistant tool body are required.\u003c\/p\u003e\u003cp\u003eThe ACC-HB035125 is suited for small-bore applications in CNC machining centers, manual lathes, and mill-turn equipment. Its compact geometry makes it appropriate for tight clearance bores in medical components, instrument housings, watch parts, hydraulic valve bodies, and similar precision work. The submicron carbide grade provides the hardness and wear resistance needed to maintain size and surface finish across extended production runs in ferrous and non-ferrous materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide construction for high rigidity and wear resistance in small-bore work\u003c\/li\u003e\n\u003cli\u003eHelical boring bar geometry supports chip evacuation in shallow blind bores\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for standard CNC and manual lathe setups\u003c\/li\u003e\n\u003cli\u003eBright finish coating — no added coating thickness to affect dimensional accuracy\u003c\/li\u003e\n\u003cli\u003e0.035-inch minimum bore diameter enables entry into very tight internal features\u003c\/li\u003e\n\u003cli\u003e1.5-inch overall length with 0.125-inch shank fits standard small-bore tool holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in tool holders and boring systems accepting a 0.125-inch shank diameter.

Ensure the shank is fully seated and clamped in the tool holder to the holder manufacturer's specification before starting the spindle. At this diameter, even minor runout or insufficient clamping force will degrade bore quality and can fracture the carbide shank. Consult the tool holder manufacturer's documentation for appropriate clamping torque and projection length guidelines.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBoring Bar Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.035 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Submicron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Bright\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0625 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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ACC-HB035125\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51746312978738,"sku":"ACC-HB035125","price":37.77,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a3e3b0a1857601e8a984b407800f027e.jpg?v=1788868205","url":"https:\/\/voomisupply.com\/products\/accupro-acc-hb035125-helical-boring-bar-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
