Right cutting or left cutting snips. What is the difference? Standard tin snips Shape and straight cutting snips Shape and straight cutting snips are real "all-rounders". They can cut through a metal sheet (straight-cut) as well as cut large and small contours or radii (outlinecut). In this case, it does not matter whether you are cutting at the edge (edge cut) or at the centre of a sheet. You can naturally use shape In standard tin snips, edges and handle and straight cutting snips for notching- Left cutting Right cutting are traditionally forged into one unit. operations. snips snips The force required for cutting is deter- mined by the ratio of edge length to the handle length. Right cutting snips are sharpened and designed so that they can cut right radii (i. e. a curve from left to right) easily. Left cutting snips are the best for radius cuts from right to left. Compound leverage snips Shape cutting snips The common perception is that, right cutting snips are for right-handers, and left cutting snips for left-handers. This is not true. In fact, it is the other way round. If you, a right-hander, are cutting Shape cutting snips are best suited a radius (see above, from left to right), when you want fine and narrow radius using right cutting snips, you have to cuts near the edges of a metal sheet. cut outwards from your wrist. With left You can use the delicately shaped edge cutting snips, (radius is then from right of these snips to cut extremely narrow to left) you can cut inwards from your shapes or curves without any problem. wrist. This is considerably more ergono- mic. Try it out once! Compound leverage snips comprise a cutter head and a handle. The compound Straight cutting snips action produces additional leverage. Do you wish to cut a metal sheet at the centre and/or near the edges? Then the perfect tool for you is the straight cutting snips. You can use long edges of this tool to cross-cut and notch large metal sheets quickly and precisely with less effort. 2 Simply better. 4.

Caution! Manual sheet metal snips may only be used to cut thin sheets of soft metals and steel. They are not suitable for cutting through round or rectangular section metal shapes such as wires for example. 3 The latest generation of leverage snips Low-fatigue continuous cutting Frictionless robust The shape and straight cutting snips D39ASS are particularly smooth running and extremely wear-resistant: Q due to sintered steel insert in the joint area Q due to permanent threaded connection of the joint area with stable stud bolt Effort-saving Q due to stainless steel panel over the joint for It is possible to use the complete protecting the spring beneath cutting length with every cut: Q due to a significantly reduced handle opening angle Easy to use Right and left-handed users can Perfect cornering lock and unlock the snips with They enable high-precision ease, without a change in grip. cutting of curves in the tightest Q due to central positioning of You Tube of radii and, with less risk of the latch on the top handle scratching the surface: Q due to extremely compact cutter head with partially sunken threaded head connection Shape and straight cutting snips Q For continuous, straight and curved cuts Order-No. Overall length Blade length Q Extremely compact cutter head with a partially countersunk head screw con- mm " mm " mm kg qty.
