Original Press Release:
STM Tap Holding System Features One-Touch Axial Adjustment
Franklin, TN, March 1, 2006 -- NT USA Corporation has introduced the new STM Tap
Holding System that features one-touch axial adjustment without the need for tools.
With the STM Tap Holding System, tap projection length can be adjusted simply by handrotating the guide ring on the outside of the toolholder. Axial adjustment range varies depending on the size of the STM Toolholder, but is as high as 15mm (0.591").
Taps are securely held in place by one piece steel spring collets.
Taps are further prevented from rotating by interchangeable preset drivers that secure the squares on the tap shanks. The combination of spring collets and interchangeable preset drivers provides two benefits: (1) a wide variety of tap sizes can be used with a single toolholder and (2) higher accuracy than traditional spring-type tap collets.
The STM Tap Holding System is also designed to accommodate high pressure coolant. The
system can accommodate 1,000PSI of coolant pressure for tap sizes less than 19mm (0.748") and 725PSI of coolant pressure for tap sizes 20mm (0.787") and above. Coolant can be delivered either through the tap or along the side of the tap using the STM's patented onepiece steel collets.
The STM Tap Holding System is designed for use with machines that have a synchronized
tapping function. STM Toolholders are available in CT, BT, HSK and straight shank styles. Tap collets are available to accommodate metric, unified and pipe-taper thread taps in a wide variety of sizes up to M30 (metric), 1-1/8 (unified) or ¾ (pipe-taper).
