Product Information

Tuscan HSK63A 4mm SLIM Heat Shrink Holder, 120mm Gauge Length

Tuscan Heat Shrink tool holders are available in BT40, SK40 and HSK63A tapers and in various shank diameters between 3mm-20mm, with slim 3° and standard 4.5° tool-nose options available. All Tuscan Heat Shrink tool holders are balanced to 25,000RPM @ G2.5 as standard. Heat Shrink, or Shrink Fit, tool holders use the expansion and contraction properties of metal to provide extremely powerful tool holding. Heat Shrink tool holders create a more uniform, rigid connection between the CNC machine and the tool resulting in less vibration and a noticeably smoother cut. Since there is no collet or collet nut on a Heat Shrink holder, those inherent tolerances are not compounded, therefore providing unmatched run out accuracies of ≤ 3 micron (0.003mm). The improved tolerances equate to improved finish quality and up to 30% longer tool life!
