Efficient cutting tool designed for precise 45degree cuts to ensure accurate insulation work. Measurement support with four size options to help achieve accurate measurements and reduce installation mistakes significantly. Robust materials made from resilient 0mm thick stainless steel for elasticity and resistance to erosion, suitable for varied environments. Adaptable sizing range adjustable to fit pipe diameters between 60 to 90mm, enabling use across a wide range of applications. Use in onsite HVAC installations for residential and small commercial buildings, where precise 45degree cuts improve joint quality and reduce gaps. Use on field repairs with varying pipe sizes, using the adjustable sizing range to ensure proper fit and faster installation. Use in fabrication workshops for long runs requiring consistent 45degree ends before applying insulation jackets.
