Key benefits — why you need this tool holder Reliable clamping under load: the secure locking mechanism keeps tools clamped during high‑speed milling and heavy cuts, reducing tool slip, vibration, and premature wear. Faster tool changes and less downtime: the integrated quick‑change unloading feature speeds tool swaps in multi‑operation workups and production cells. Consistent accuracy and longer life: one‑piece, hardened steel construction and tight, ground tolerances deliver stable seating, low runout, and repeatable results part after part. Simple integration with existing machines: designed for BT40 spindles and compatible with standard BT40 tooling and common CNC milling centers, supporting carbide and HSS tools for milling, drilling, and pocketing. Key features Secure locking mechanism: reliable clamping performance for high‑speed milling and aggressive cuts; minimizes tool movement and wear. Integrated one‑piece design: simplifies installation and increases rigidity on BT40 spindles for consistent spindle/tool interface. Quick‑change unloading: reduces tool change time to keep cycle times tight in multi‑op and high‑volume operations. Precise locking tolerances: engineered for repeatable seating and low runout to maintain consistent accuracy across runs. Broad BT40 compatibility: accepts standard BT40 tooling; supports both carbide and HSS tools per BT40 standards for milling, drilling, and pocketing. Durable construction: made from hardened steel and ground to tight tolerances for long service life and dependable machining accuracy. Typical applications Job shop contour and finish work: switch quickly between roughing and finishing passes on aluminum, with consistent seating and minimal setup between operations. Production pocketing of steel parts: run aggressive pocketing cuts with strong clamping and stable tool seating to maintain cycle rates and part quality. Mixed‑operation cells: combine drilling, boring, and pocketing with rapid tool changes to keep multi‑op cycle times tight and predictable. Material and compatibility summary Material: hardened steel, precision ground. Spindle standard: BT40. Tooling: compatible with standard BT40 tooling; supports carbide and HSS tools within BT40 specifications. Functions: milling, drilling, pocketing with reliable clamping, quick-change unloading, and consistent repeatability. What this delivers in practice Reduced scrap and rework from improved seating and lower runout. Lower tooling costs from reduced slip and wear. Increased throughput from faster tool changes and stable clamping under heavy cuts.
