Carboloy 3.45-0100-RL NMTB40 Milling Tool Holder

The Carboloy 3.45-0100-RL is a milling tool holder designed for the NMTB40 taper used on machine centers. Marketed as Carboloy NMTB40-TH Machine Center, this holder provides a rigid interface to secure cutting tools with a 40-taper shank for precise seating in CNC milling operations. The 3.45-0100-RL part number identifies the specific Carboloy configuration within the NMTB40 family, ensuring compatibility with standard NMTB40 tooling and workflows associated with this taper. Used in general milling across metalworking environments, it supports tool changes and stable performance on machine centers that rely on NMTB40 tooling, a common choice for mid-range to larger milling applications where durable, repeatable tool mounting is essential. As with Carboloy tool holders, the design emphasizes precise fit and rigidity to minimize runout during cutting.
