Introducing the Valenite S24U-MCKNR-4 Boring Bar, a high-performance tool engineered for precision and durability in heavy-duty machining applications. This boring bar is a part of Valenite's UNI-MOR series, known for its versatility and reliability.

The Valenite S24U-MCKNR-4 is a solid carbide boring bar, designed to ensure accurate and consistent hole boring. It is manufactured using Valenite's proprietary U-Grade Plus substrate, a high-quality, high-performance material that provides excellent strength and rigidity. The U-Grade Plus substrate also allows for efficient cooling, minimizing thermal expansion and ensuring long tool life.

The S24U-MCKNR-4 features a MCKNR grade boring head, which is known for its excellent wear resistance and high red hardness. This grade is ideal for machining hard and tough materials, making it a popular choice for aerospace, automotive, and heavy machinery industries. The head is precision ground to ensure a perfect fit and accurate run-out, which is crucial for maintaining consistent hole sizes and avoiding tool breakage.

The Valenite S24U-MCKNR-4 boring bar also comes with a standard UNI-MOR shank, which is compatible with most CNC machines and boring machines. The shank is designed to provide secure clamping and excellent vibration damping, reducing the risk of tool deflection and ensuring consistent cutting performance.

In terms of dimensions, the S24U-MCKNR-4 has an overall length of 11 inches (279.4 mm), a diameter of 0.625 inches (15.9 mm), and a shank length of 6 inches (152.4 mm). The bar is available in various lengths and sizes to accommodate different machining applications.

Overall, the Valenite S24U-MCKNR-4 boring bar is a high-quality, reliable, and versatile tool that is perfect for heavy-duty machining applications involving hard and tough materials. Its precision-ground head, efficient cooling, and vibration-damping shank ensure accurate hole boring and long tool life, making it a valuable addition to any machining shop.
