In addition to a smaller burr, cleaner bur- nish and break patterns on the perforation, matching the clearance to the material also can extend the service life of the punch. This literature is ideal for those involved with all types of punching or perforating including high-speed, high-volume punching. Dayton Progress: 937/859-5111; www.daytonprogress.com
In traditional 60-deg. threads,
the gap between the upper edges of the male and female threads can lead to vibra- tion-caused loosening. Stress concentra- tion and fatigue at the first few engaged threads also can be a problem. The unique profile of Spiralock threads closes the gap that causes loosening, improving the integrity and reliability of threaded joints.
machine taps by enhancing the tool’s geometry, surface coatings and flute angles, as well as shapes and nose size. These improvements promise to enable higher-speed production and significant- ly extend tool life. PVD coatings enable tap- ping as much as 50-percent faster than with previous nitride or bright finished taps, and help the taps to cut smoothly in deeper holes where there is little coolant or lubrication. Also available: a dual-layer PVD coating.

Compact Power Unit Drives Small-to-Midsized Die-Clamping Setups
The Hilma Div. of Carr Lane Roemheld, Fenton, MO, introduces an electrically driven high-pressure hydraulic power unit designed for small and midsized die- clamping and lifting systems. The modu- lar unit, compact and lightweight, comes ready for installation, complete with motor,
Thread-form tapping has traditionally been a relatively slow machining operation, due to its limited visibility and necessary precision. Not content to let tapping tech- nology become stale, Stanley Engineered Fastening has improved its lineup of
