STF has been designing and manufacturing quality diamond turning tools for 25 years. We excel at producing custom boring bars, form tools, multi-tipped inserts, full face inserts and solid rounds. We have the equipment to tip nearly any kind of turning tool, and our regrind and retip programs allow customers additional tool usage at a fraction of the price of new tools.
Each month STF produces a wide variety of PCD tipped inserts for turning non-ferrous metal, plastic and carbon fiber products. Our PCD tips are lasered to size in-house and
then brazed using one of our vacuum furnaces or one of our many induction brazing
machines. Smaller batch sizes are completed on a manual machine while larger lots
are finished on one of our 10 robot loaded CNC grinders. Tools requiring edge
preparation are also honed or polished in-house.
