The Carpenter Square CS300 has been designed for the workshop environment where quality and pride in craftsmanship in your own work and ours is paramount.

The CS300 is fully CNC machined from the highest quality German cast aluminium tool plate.

• Fully CNC machined
• Accurate to at least 0.01° over 300mm
• British made
• Highest quality German cast aluminium 
• 2 precision laser marked millimetre scales on each side
• Stainless steel location dowels
• Stainless steel machine screw fixings
• Protective anodised finish

The single piece aluminium square is milled with several passes on our in-house CNC milling machines to ensure absolute squareness. This is abutted on each side by two aluminium cheeks that are machined at the same time as the body to provide consistency in the squareness and part tolerance. The parts are then pressed together using two stainless steel locating dowels with extra stainless steel machine screws to secure the cheeks.

How It's Made: TrigJig Carpenter Square Hand Tool

The CS300 undergoes a glass bead blasting process to provide a matt finish before then being anodised in our brand colours. The anodising creates a hard protective layer on the surface of the aluminium that offers corrosion and scratch resistance, as well as giving the CS300 the stylish and striking appearance that our customers have come to expect from TrigJig tools.

There are two handy millimetre scales on each side of the square to help with measuring, marking and laying out.
