Adapt straight-shank cutting tools into high-torque milling chucks with supreme rigidity and extreme clamping force using Collets for Heavy-Duty Chucks. Often referred to as cylindrical reduction sleeves, these heavy-walled collets are specially engineered to fit inside powerful, thick-walled milling chucks (such as C32 or C42 series). Unlike flexible multi-slot spring collets, these components prioritize maximum cross-sectional density and minimal slots to deliver massive, unyielding radial compression. This rigid setup guarantees positive mechanical clamping, completely eliminating tool slippage, pull-out, and deflection under high feed rates during intensive roughing and deep-slotting operations.
