PSI have created the quickest and most convenient pen mandrel on the market. Its "keyless" feature allows you to instantly hand loosen and tighten the collet that secures the 7mm mandrel shaft.
In addition, you can quickly slide and lock the shaft so you get the exact length of your turning and a guaranteed perfectly concentric fit, so you’ll no longer deal with the hassle of spacer bushings or separate tightening wrenches.
The system also includes:
- Five 7mm bushings
- Knurled nut
- 7mm brad point drill bit
- Knurled lock nut
- Tightening bars (to use if needed).
