75 DegreeSSBCR1212H09 Screw type external cutting tool holder

The 75-degree screw-type external cutting tool holders (including models like SSBCR1212H09, SSBCR1616H09, SSBCL2525M12, etc.) offer a range of standout advantages for precision metalworking:


  1. Superior Clamping Stability: The screw-type design ensures secure and rigid blade fixation, minimizing vibration during high-speed or heavy-duty cutting. This stability translates to smoother cuts, reduced tool wear, and consistent machining accuracy—critical for tight-tolerance parts.
  2. 75-Degree Geometry for Versatility: The 75-degree angle balances strength and accessibility, making it ideal for both roughing and finishing external turning operations. It excels in machining shafts, disks, and cylindrical components, even in confined spaces where larger angles might struggle.
  3. Durable Construction: Crafted from high-grade alloy steel (such as 42CrMo), these tool holders withstand intense cutting forces and prolonged use without deformation. This durability lowers replacement frequency and reduces downtime in busy workshops.
  4. Wide Compatibility: Designed to fit standard insert sizes (matching codes like H09, K12), they seamlessly pair with common carbide or ceramic inserts, allowing machinists to adapt to different materials (steel, aluminum, alloys) without switching tool holder systems.
  5. Square Shank Reliability: The square shank design (with sizes 12×12mm, 16×16mm, up to 25×25mm) ensures firm mounting on CNC or conventional lathes, preventing slippage and enhancing operational safety during high-torque cutting.
  6. Cost-Effective Performance: By combining long tool life, reduced setup time (thanks to easy insert changes), and consistent results, these holders lower overall production costs—making them a smart choice for both small shops and large-scale manufacturing lines.


Whether for automotive parts, machinery components, or precision engineering, these tool holders deliver the strength, precision, and flexibility modern machinists demand.

Introducing our 75 Degree Screw Type External Cutting Tool Holders, a comprehensive range of high-performance machining solutions encompassing models SSBCR1212H09, SSBCR1616H09, SSBCR2020K09, SSBCR2525M09, SSBCR2020K12, and SSBCL2525M12. Engineered to meet the rigorous demands of modern metalworking, these tool holders are the perfect blend of precision, durability, and versatility.

Crafted from top-grade alloy steel, these tool holders are built to endure. The robust construction of 42CrMo steel provides exceptional strength and toughness, enabling them to withstand the high forces and vibrations generated during heavy-duty cutting operations. This resilience ensures minimal deformation over time, safeguarding the integrity of your machining processes and reducing the need for frequent replacements.

The defining feature of these tool holders is their 75-degree cutting angle, a carefully optimized geometry that strikes the perfect balance between cutting efficiency and chip control. This angle is particularly well-suited for external turning applications, whether you're performing roughing to rapidly remove material or finishing to achieve a mirror-like surface finish. The 75-degree angle also allows for efficient chip evacuation, preventing chip buildup that could otherwise lead to tool wear and surface imperfections.

The screw-type clamping mechanism is another highlight, offering unparalleled stability and security. By firmly securing the cutting insert in place, it eliminates any risk of slippage during operation, even at high speeds and feeds. This not only enhances the precision of your cuts but also extends the lifespan of your inserts, maximizing your return on investment.

Designed with compatibility in mind, these tool holders are engineered to work seamlessly with a wide range of standard inserts. The designations such as H09, K09, K12, and M12 correspond to specific insert sizes and geometries, allowing you to easily swap out inserts to suit different materials and machining requirements. Whether you're working with hard metals like steel and stainless steel or softer materials like aluminum and brass, these tool holders have you covered.

Available in a variety of shank sizes, including 12×12mm, 16×16mm, 20×20mm, and 25×25mm, these tool holders are suitable for use on both CNC lathes and conventional turning machines. The square shank design ensures a secure and precise fit in the machine tool's turret or tool post, further enhancing stability and accuracy.


In summary, our 75 Degree Screw Type External Cutting Tool Holders are the ultimate choice for machinists who demand the best. With their rugged construction, innovative design, and exceptional performance, they're guaranteed to elevate your machining operations to new heights of productivity and precision.
