With a minimum bore diameter of 0.285 inches and a 1\/4-inch shank diameter, this bar handles small-bore finish work where rigidity and dimensional accuracy matter. The solid carbide construction reduces deflection compared to steel-shanked alternatives, making it well suited for tight-tolerance applications. Insert retention is by screw clamp, and the bar is compatible with WPGT-style inserts. Coolant-through capability helps clear chips and manage heat in deep-bore cuts. Overall length is 6 inches.\u003c\/p\u003e\u003cp\u003eThis boring bar is used in production and job-shop machining environments for boring small-diameter holes in ferrous and non-ferrous workpieces. It is appropriate for applications where minimum bore diameter constraints make larger tooling impractical. The right-hand cut orientation suits standard lathe setups. Maximum bore depth reaches 2.5 inches, making it capable for moderately deep small-bore operations in both manual and CNC turning centers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for maximum rigidity and reduced deflection in small-bore cuts\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.285 inches suits tight internal diameter requirements\u003c\/li\u003e\n\u003cli\u003eRight-hand cut orientation for standard lathe and turning center setups\u003c\/li\u003e\n\u003cli\u003eScrew-clamp insert holding method provides secure, repeatable insert indexing\u003c\/li\u003e\n\u003cli\u003eCompatible with WPGT inserts for broad grade and geometry selection\u003c\/li\u003e\n\u003cli\u003eCoolant-through design assists chip evacuation and thermal management in deep bores\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with WPGT-style inserts.

Secure the shank fully within the tool block or boring bar holder to the depth recommended by the machine tool manufacturer, ensuring minimum overhang to maintain rigidity. Power down and lock out the machine before changing inserts or adjusting the bar position. Do not exceed the maximum bore depth of 2.5 inches, and verify insert grade selection against workpiece material before running.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.285 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: HBBG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: WPGT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 6.25 inches L x 0.5 inches W x 0.5 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2 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: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: H08614828\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51747439051058,"sku":"H08614828","price":391.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9de3a008a291826c80576bc75cae3804.jpg?v=1788880248","url":"https:\/\/voomisupply.com\/products\/hertel-h08614828-indexable-boring-bar-0-285-in-min-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
