Machinable Pitbull clamps offer the same clamping strength as the standard version but feature a soft, aluminum clamping face that can be milled to match your part geometry. This allows for maximum contact on curved or irregular surfaces while maintaining the same ultra-low profile. They're ideal for finishing operations on contoured parts or any application where you want aggressive clamping without part deformation.
