All Kingsland Punches and Dies are manufactured to the highest quality. All tooling is manufactured from top quality D2 toolsteel and heat treated for a long and productive working life.

In theory the die clearance should be 10% of the material thickness being punched.
A 10% clearance is ideally suited for sheet metal thicknesses on turret punching machines, but less favorable for thicker material. When using 10% clearance on thicker material you might experience an excessive amount of machine vibrations "heavy banging or shaking when punching through the material". This is why we do recommend below clearances being used.

Material thickness up to 4mm:        0.2 - 0.4mm
Material thickness 5 to 12mm:        0.8mm
Material thickness 12 to 20mm:      1.2mm
Material thickness 20 to 25mm:      1.6mm
 
As an example, if you are to punch in 10mm mild steel, we do recommend a die of 10.8mm (10mm die + 0.8mm clearance)
 
Please note:

• The above information is a guide only.
• For all single cylinder punching machines, such as XM, XA and Compact models, the minimum die clearance is 0.4mm.
