Product Description

The quickest and most convenient pen mandrel on the market. The "keyless" feature allows you to instantly hand loosen and tighten a collet that secures the 7mm mandrel shaft. Plus you can quickly slide and lock the shaft so you get the exact length of your turning and a guaranteed perfectly concentric fit. You’ll no longer deal with the hassle of spacer bushings or separate tightening wrenches. The system also includes five Slimline Bushings (#PKM-BUSH3), knurled nut, 7mm brad point drill bit and knurled lock nut and tightening bars (to use if needed).
