Different sizes of roller are equipped, which can be changed to adapt to different radian <br> <br>Description: <br> The tool must be used in a fixed table, otherwise uneven force, the effect will not good. <br> Different sizes of roller are equipped, which can be changed to adapt to different radian. <br> Adding lubricating oil to keep the bending tool work smooth and anti-rust. <br> It can bend iron 1.0 mm, aluminium: 1.2 mm, stainless steel: 0.8mm, effective flanging height is 10 cm. <br> <br>Working Height: 100mm <br>Gross Weight: 3200g/set <br>Packing Size: 9.0" x 5.2" x 6.5"(230 x 132 x 165mm) <br> <br>Usage: <br>1. Prepare the strip and metal bending tool at first. <br>2. Put the diameter 40mm roller onto the bender. <br>3. Make the two positioning devices close to the roller, and then use spanner to tighten the bellow two screws. <br>4. The two positioning devices close to the roller. <br>5. Bending the strip by hand. <br>6. Finishing by roller of 40mm diameter. <br>7. Change the other roller of diameter 30mm/20mm onto the bending tool, you can attain bended strip with different radian. <br>Tips: You need to adjust the two screws to make the two positioning device close to the roller every time, if you change different diameter roller. <br> <br>Remark: <br>Adding lubricating oil to keep the bending tool work smooth and anti-rust.
