A CNC Tool Holder is a critical interface between the cutting tool and the spindle of a CNC machine. Engineered for high-speed, high-precision machining, these holders ensure secure clamping, minimal runout, and optimal performance in turning, milling, drilling, and boring operations.
Key Features:
✅ High-Strength Construction:
Manufactured from alloyed hardened steel (HRC 58–62) to provide excellent rigidity, vibration dampening, and resistance to wear under high-load conditions.
✅ Precision Ground Taper & Bore:
Each tool holder is ground to tight tolerances (≤0.003 mm) to ensure perfect concentricity and alignment, reducing tool runout and extending cutting tool life.
✅ Wide Compatibility:
Available in various international standards such as BT, CAT, HSK, ISO, and ER collet types, ensuring compatibility with most CNC machining centers and turning machines.
✅ Secure Clamping Mechanism:
Incorporates advanced clamping systems such as ER collet chuck, side-lock, hydraulic, or shrink-fit systems for secure and vibration-free tool holding.
✅ Dynamic Balancing:
Tool holders are balanced to G2.5 or G6.3 standards for high-speed spindle applications, minimizing machine wear and improving machining surface finish.
✅ Anti-Corrosive Finish:
Surface treated with black oxide, nickel plating, or TiN coating to protect against rust and wear, even in coolant-heavy environments.
Applications:
- High-speed CNC milling and drilling
- Precision turning and boring operations
- Tool holding in vertical and horizontal machining centers
- Used across automotive, aerospace, die & mold, and heavy engineering sectors
