How to cut Perspex - Kitronik University This Kitronik University course is part of the working with materials course and covers how to cut and scribe Perspex.

Sawing Perspex

Powered saws with blades that have alternatively bevelled teeth, as normally used with aluminium, are particularly suitable for Perspex®. Band saws, jig saws and fret saws may also be used. The recommended conditions for sawing Perspex® are shown in the table below.
Saw Type Optimum Blade Speed (m/min) Optimum Saw Pitch Recommendation
Sheet Thickness Teeth/cm
Circular Saw Carbide Tipped 3000 All Thicknesses 0.8-1.6 N/A
Bandsaw 1500 Up to 3mm 3-13mm Over 13mm 6-8 4-5 1.5-2 Saw guides as close together as possible to prevent twisting
Jig Saw Fret Saw Non-Critical Up to 6mm 5-6 Allow blade to stop before withdrawing from saw cut

Scribing Persepx

Small pieces of Perspex® up to 4mm thick may be conveniently cut in a straight line by deeply scribing one or both surfaces several times with a sharp metal scriber, or stanley knife. Clamp the sheet with the scribed line uppermost and pressing sharply down over the edge of a bench or desk that has an unbevelled edge. Please note, this technique is not suited to extruded.
