Shaping Sheet Metal with Specialized Tools
Sheet metal is used in a wide range of applications from HVAC work to auto body repair. Skilled trades workers rely on specific sheet metal tools to accurately cut, bend, form, and manipulate sheet metal into final products.
Cutting sheet metal tools
Tin Snips – Tin snips, available in curved, straight and aviation styles, manually cut sheet metal.
Nibblers – Nibblers use a cutting blade to remove small, gradual curves or holes in sheet metal.
Shears – Shears with compound leverage can cut straight lines in sheet metal up to 16 gauge thick.
Cutting Machines – Mechanized sheet metal cutting machines use rotating blades or lasers for high volume, precision cuts.
Bending and Forming sheet metal tools
Hammers and Mallets – A planishing hammer or mallet smooths and shapes metal through repeated striking.
Brakes – A brake makes straight bends by clamping and bending metal between a punch and die.
Slip Rolls – Slip rolls use three rotating steel wheels to bend metal to a desired radius.
Stamping Presses – Stamping presses use formed dies to punch shapes or emboss patterns into sheet metal.
Shaping and Finishing sheet metal tools
Anvils and Stakes – Anvils or stakes support and shape metal hammered against them.
Sand Bags – Sand bag forming utilizes sand-filled bags to contour sheet metal through hammering.
English Wheels – An English wheel machine shapes sheet metal through two steel wheels squeezing the workpiece.
Conclusion
Sheet metal workers rely on specialty tools like shears, brakes, and slip rolls to efficiently and accurately form sheet metal. Investing in quality sheet metal tools allows for professional looking results.
