Description
Meet the Carmex Carbide Round Shank Holder Through Coolant — a precision tool holder designed for through-spindle coolant, engineered to secure indexable carbide inserts with stability and accuracy. Part of the Mini Tools family, it supports both T8 and T10 insert types and features an 8mm shank with 20mm reach.
- Through Coolant Design: Enables coolant to flow through the holder, improving chip evacuation and maintaining insert temperature during cutting.
- Compatibility: Works with both T8 and T10 indexable carbide inserts for flexible tooling setups.
- Shank and Reach: 8mm round shank with a 20mm reach to fit compact machine envelopes and reach tight pockets.
- Carbide Construction: Built from carbide material for rigidity, wear resistance, and consistent performance under demanding milling conditions.
- Vibration Resistance: Excellent vibration resistance to reduce chatter and improve surface finish.
- Tool Family: Part of Carmex’s Mini Tools family of insert holders, designed for reliable, compact tooling ecosystems.
With its 8mm round shank and 20mm reach, this holder delivers precise insert alignment and stable performance in tight machining spaces. The through coolant capability supports efficient chip clearing and helps extend tool life, while compatibility with both T8 and T10 inserts provides flexible tooling without swapping holders. The carbide construction and proven vibration resistance translate into consistent finishes, fewer rework passes, and longer tool life in everyday milling tasks.
