Reducing Thrust Loads During Rigid Tapping
Some amount of synchronization error is inevitable with rigid tapping. By allowing just a slight amount of axial movement to compensate for synchronous errors, this tapping holder is said to reduce thrust load by as much as 90 percent.

Modular Drill Diameter Range Expands
The Ken TIP modular drill system from Kennametal features various solid-steel bodies (3 × D, 5 × D and 8 × D, among others) and replaceable drill points for precision hole-making in steel. The modular design allows users to keep the drill bodies in a machine or holder and replace drill points as needed. Running at speeds comparable to those of solid carbide drills, the system offers high metal removal rates compared to common modular drills and reduces setup times, the company says.
