The Eckold KF170PD Kraftformer packs a lot of power for a small portable unit. It can shrink, stretch, punch, notch, clinch, planish, and has doming dies available. The sturdy base allows for a comfortable work height while still being easily moved across the shop. Quickly change the air powered machine from single to multi-stroke with the flip of a switch. The KF170PD features a 6.7 inch throat depth, 5.75 inch throat height, and a 14 gauge (2.0mm) mild steel capacity (based on tooling).
