Magnum Inside Threader Carbide Insert For CS7 & CS9 (JCL15120)

Produce clean, accurate internal threads without the frustration of hand-grinding HSS bits. This JCL15120 carbide insert is designed for internal threading operations on lathes equipped with CS7 and CS9 boring bars. The industrial carbide construction ensures that the thread profile remains sharp and consistent across multiple passes, even when working with hardened steels or stainless alloys.

Features

• Precision Thread Profile - Engineered for 60-degree unified and metric internal threading.
• Internal Clearance - Optimized geometry prevents the tool flank from rubbing in small diameter bores.
• Solid Carbide - Handles high frictional heat for extended tool life compared to high-speed steel.
• Direct Compatibility - Fits perfectly in CS7 and CS9 series internal threading/boring tool holders.
