CentroGrip™
CentroGrip High-Precision Collet Chucks
By Diebold
Engineered for exceptional performance in high-speed cutting, CentroGrip™ collet chucks deliver unbeatable precision and stability.
Ultra-low run-out:
< 1µm for the holder body, < 2µm for colletsSymmetrical clamping nut:
No air turbulence or vibration — just smooth, consistent millingOptimized for HSC:
Perfect for demanding high-speed machining applications
💡 Precision you can rely on. Performance you can feel.
Why CentroGrip?
Extreme precision:
≤1µm runout between tool taper and collet taper
≤3µm at 3xD (that’s just 0.0001”)High clamping force:
Up to 50% more than standard ER systemsLow vibration, high damping:
Symmetrical nut design eliminates turbulence—even at high RPMMirror-like finishes:
Ideal for medical, aerospace, and micro-machining
