H08j-H32s Svvcn Series HSS Internal Boring Bar CNC Turning Tool Holder for Vc Inserts

H08j-H32s Svvcn Series HSS Internal Boring Bar CNC Turning Tool Holder for Vc Inserts. High-strength HSS substrate with built-in anti-vibration structure, effectively suppress tool chatter during deep hole boring, deliver smooth workpiece surface finish. 95 SCLCR clamping structure, perfectly match CCMT12 carbide inserts for internal turning, facing and chamfering. 25mm & 32mm shank options: H25S/H25T for light cutting, H32U/H32T for heavy-duty machining. Accurate insert positioning slot ensures stable clamping, avoid insert displacement & reduce machining tolerance error. Integrated heat treatment enhances overall hardness & abrasion resistance for long-time continuous CNC processing. Suitable for small inner bore, deep hole, thin-wall parts, stainless steel and aluminum alloy workpieces. Anti-rust surface coating resists coolant corrosion, durable for harsh long-term workshop working conditions. Laser engraved model & size marks on bar body, easy for factory storage and tool classification management. Compact bar design avoids collision interference when machining narrow inner cavity workpieces. Strict dimensional tolerance test before shipment, interchangeable with most mainstream boring holders to cut replacement cost.
