DCMT Insert Holder
A DCMT Insert Holder is a versatile turning tool holder specifically designed to securely clamp DCMT style indexable cutting inserts. The ISO designation “DCMT” indicates a rhombic-shaped insert with a 55-degree nose angle, a positive rake angle, a clearance angle, and a central mounting hole. The positive rake angle makes these inserts well-suited for light to medium machining operations, including finishing and semi-finishing of various materials, particularly softer or more ductile ones like aluminum, stainless steel, and low-carbon steel. The 55-degree angle offers excellent clearance, making them ideal for profiling and machining complex geometries with reduced risk of interference.
The primary function of a DCMT Insert Holder is to provide a stable and accurately positioned platform for the DCMT insert. This ensures precise material removal and excellent surface finishes, especially in intricate machining tasks and tight spaces. The holder features a precision-machined pocket that matches the specific shape and dimensions of the DCMT insert, allowing for secure and repeatable clamping, typically achieved with a screw or lever mechanism. This robust clamping prevents insert movement and vibration during machining, which is crucial for achieving high-quality results, especially in finishing passes and when creating detailed contours.
DCMT inserts are favored for their ability to produce fine finishes and their excellent accessibility due to the 55-degree angle. They offer two cutting edges per side, totaling four usable edges per insert, providing good tool life and cost-effectiveness. The corresponding DCMT Insert Holders are designed for ease of use, enabling quick and straightforward insert changes, minimizing machine downtime. Available in various shank sizes and configurations to suit different machine tool types and application needs, DCMT Insert Tool Holders are a valuable asset in precision machining environments where good surface finish, lower cutting forces, and excellent clearance are required.
