On the ER mini-nut holders from Techniks, nut diameters range from 0.63" to 1.02" (16 mm to 28 mm) to permit machining where standard ER nuts cannot fit. ER11, ER16 and ER20 sizes are available for CAT40, CAT50, BT30 and BT40 spindles.
The mini-nut holders are manufactured to the highest standards to extend perishable cutting tool life and improve CNC machine performance. Each taper is precision ground to exceed AT3 industry standards, and TIR is only 0.0001" maximum. They are factory bablanced to 18,000 rpm at G2.5, and each holder is individually lab tested for accuracy and balance. A lab certification documenting test results comes with each holder.
