Balax 99453941 12-32 BH6 TiN Thredfloer Thread Forming Tap

The Balax 99453941 is a 12-32 UNC Thredfloer (thread forming/cold forming) tap in BH6 tolerance class with a TiN (Titanium Nitride) coating, visible as the bright gold color on the threaded section in the photos, contrasted by the black oxide finish on the shank. Thredfloers are chipless, fluteless taps that displace material rather than cut it, producing stronger threads with no chips — making them ideal for through and blind holes in ductile materials such as aluminum, brass, mild steel, and stainless steel. The BH6 tolerance designation indicates a ground thread form calibrated for a 3B class fit with controlled oversize pitch diameter to accommodate TiN coating buildup, per Balax's standard Thredfloer tolerance system. The square-drive shank is designed for use in standard tap holders, CNC tapping heads, and reversible tapping attachments. This tap is offered in new — other condition, individually bagged as shown, bearing the hand-written lot notation "12-32 BH6" and Balax's stamped serial number SO. 270502 on the shank.
