Features Sturdy and Lightweight: The small square is made from an excellent industrial grade aluminium alloy, which is strong and lightweight, resistant to breakage and easy to use and carry. Anodised Finish: The small square has an anodised red finish that maintains excellent finish, corrosion resistance and durability. Fitted with 4 Steel Sleeves: The small square is fitted with 4 steel sleeves so you don't have to worry about it wearing out when drilling or plotting centrelines, causing the pilot hole to become larger and lose accuracy. Multifunctional: This small square differs from the normal straightedge in that it can be used not only as a centre scriber marking tool to draw centre lines, but also as a self centring pin drilling guide jig to drill straight centre holes. Quick Drilling: This small square contains 2 pins to quickly draw the centre line and drill the centre hole, easily checking the chisel.
