Built to the HBBF toolholder style, it accepts TD-series inserts secured by a screw-clamp holding method, providing repeatable insert indexing and rigid cutting performance. The bar features a 5\/16-inch shank diameter, a minimum bore diameter of 0.36 inches, and an overall length of 4 inches. Coolant-through capability supports chip evacuation and thermal control during deep-bore passes. Right-hand cut orientation suits standard spindle configurations. Intended for use by machinists and tooling technicians in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis boring bar is suited for small-diameter internal boring applications where solid carbide construction provides the rigidity and vibration resistance required for tight-tolerance finishes. The HBBF toolholder style is commonly applied in CNC turning centers handling steel, stainless, cast iron, and non-ferrous materials. With a maximum bore depth of 3-1\/8 inches and a 0.36-inch minimum bore entry, it covers a practical range of bore sizes in a compact shank profile. The coolant-through design makes it especially effective in deep-bore scenarios where flood coolant alone cannot reach the cutting zone.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for maximum rigidity and vibration damping in small-diameter bores\u003c\/li\u003e\n\u003cli\u003eCoolant-through design directs cutting fluid directly to the insert tip for improved chip control and tool life\u003c\/li\u003e\n\u003cli\u003eScrew-clamp insert holding method ensures secure, repeatable TD-series insert indexing\u003c\/li\u003e\n\u003cli\u003eRight-hand cut orientation compatible with standard CNC lathe and turning center spindle rotation\u003c\/li\u003e\n\u003cli\u003e5\/16-inch shank diameter fits standard boring bar holders and quick-change tooling systems\u003c\/li\u003e\n\u003cli\u003eHBBF toolholder style supports a broad range of TD-compatible insert geometries and grades\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eAccepts TD-series indexable inserts. Designed for use in HBBF-style boring bar holders with a 5\/16-inch bore.

Ensure the machine spindle is fully powered down and locked out before mounting or removing the boring bar. Verify insert seating and screw torque per the insert manufacturer guidelines before running the first cut. Confirm shank clamping length meets the toolholder minimum engagement requirements to prevent deflection under load.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: HBBF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.36 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 3.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3125 inches (5\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\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: TD series\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Right Hand\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: 4.25 inches L x 0.5 inches W x 0.5 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.55 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241601\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: H59869354\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51731770638642,"sku":"H59869354","price":443.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/374ca97f7b8cc7b32d4a0ffdbca91477.jpg?v=1788734747","url":"https:\/\/voomisupply.com\/products\/hertel-h59869354-indexable-boring-bar-0-36-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
