STF Precision is proud to announce that we are now producing
a full line of polycrystalline diamond drills & countersinks.
Superior Diamond makes a Superior Drill
Most of our competitors sinter or press diamond powder into a slotted helix, a tricky prospect resulting in PCD that is soft and wears quickly. We buy thick pieces of prepressed diamond straight from the world’s leading manufacturers, who spend millions developing the best PCD.
A thin layer of titanium bonds the diamond to the carbide body. Then using the latest grinding and diamond erosion equipment, we shape the diamond into a true helix and finish the drill point.
The result is a drill with exceptional wear and chip resistance.
