Description
Mini Internal Threading Tool 3mm – 60° Partial Profile
Machine Smaller. Thread Stronger. Quote Faster.
Cutoutiltool's micro internal threading insert is the first choice of Swiss-type, multi-spindle and gang-tool lathes when 3 mm threads in steel have to be flawless, repeatable and profitable.
Why engineers switch to Cutoutiltool
60° partial-profile geometry cuts any 60° metric or UN pitch (0.5–0.8 mm / 32–48 TPI) with one insert – stock reduction of 40 %.
Sub-micron carbide + nano-TiAlN coating withstands 220 °C chip temperatures in low-carbon, alloy and stainless steels; tool life +35 % vs. uncoated micro-grain grades.
6° positive rake and 8 µm edge-hone lower cutting forces to 0.15 N µm⁻¹ – perfect for 0.4 kW spindles and brass-collet setups that stall with conventional ground tools.
Mirror-polished flutes evacuate chips from blind holes down to 1.5 ×D, eliminating "chip-pack" breakage on unmanned night shifts.
h4 shank tolerance (-0.005 / -0.008 mm) guarantees < 0.01 mm run-out in ER8 collets – no centre-alignment needed.
Instant ROI calculator
Average customer report: 28 parts per edge × 4 edges = 112 parts per insert. At 15 s cycle time you add 2.3 h extra machine uptime every week – worth $ 138 in shop-rate savings.
