Product Overview

JT50-PSC6-30 is a high-rigidity modular polygon tool holder under EGNC brand, manufactured in accordance with ISO26623 international polygon coupling standard. It adopts JT50 (SK50) 7:24 standard spindle taper matched with PSC6 three-lobe polygonal interface, with a compact effective length of 30mm to shorten tool overhang. The dual-contact structure of polygon taper and flange surface greatly improves bending resistance and stability during heavy cutting. Made of quenched alloy steel with precision grinding and G2.5 dynamic balance treatment, it features ultra-low radial runout, built-in through-coolant channel, suitable for high-speed and heavy-duty milling on JT50 CNC machining centers and mill-turn machines.

Key Features
  • Dual-contact polygon + flange surface design, twice the rigidity of conventional BT/SK tool holders, effectively suppress cutting vibration
  • ISO26623 standard PSC6 self-centering polygonal interface, repeat positioning accuracy ≤±2μm
  • Short 30mm overhang structure, small length-diameter ratio, stable processing under high feed rate
  • Hardened 20CrMnTi alloy steel body, HRC 52-56 heat treatment, wear-resistant and long service life
  • Internal high-pressure through-coolant channel, maximum bear 200bar coolant for rapid heat dissipation
  • Precision grinding processing, radial runout ≤0.002mm, dynamic balance grade G2.5
  • Modular quick-change structure, freely matched with all PSC6 series milling/turning tool heads
  • Universal JT50/SK50 7:24 taper, compatible with most vertical machining centers
