Kent Set Square 260mm 60 Deg 260B60

Kent Set Square 260mm 60° is a large format, clear acrylic set square featuring a 30/60/90° angle configuration and a calibrated ruler edge measuring to 23cm. The 260mm size provides a generous working span well suited to the demands of technical drawing, architectural drafting and geometric construction at secondary level, allowing students to draw long, accurate lines with a single placement of the instrument. The clear acrylic construction allows students to see the drawing surface beneath, supporting accurate alignment and precise placement across all technical drawing tasks.

The 60° set square is one of the two essential set squares in technical drawing practice, used to produce lines at 30°, 60° and 90°, and when combined with a 45° set square, a full range of standard angles including 15°, 75° and 105°. The 30/60/90° configuration is particularly important for isometric projection drawing, where lines are constructed at 30° to the horizontal to create accurate three-dimensional representations of objects in plan, elevation and isometric view.

Students can use the Kent Set Square 260mm 60° for a wide range of technical drawing tasks including isometric projection, parallel line construction, oblique drawing, architectural drafting and geometry exercises requiring accurate 30° and 60° angle construction. The longer calibrated ruler edge — measuring to 23cm — provides a greater measurement span than the 45° set square, making this instrument particularly useful for larger drawing formats and longer line constructions.

The calibrated ruler edge provides an additional measuring function, allowing students to mark accurate increments directly from the set square without switching to a separate ruler. The hanging hole at the top of the instrument allows for easy storage and display in the classroom, keeping instruments organised and readily accessible.

Suitable for secondary art, design and technology, mathematics and technical drawing programs, Kent Set Square 260mm 60° is a durable, well-made instrument that meets the requirements of senior students working to a high standard of technical drawing accuracy and precision.

Kent Set Square 260mm 60° is used by placing the set square flat on the drawing surface with the desired edge aligned to the drawing direction. Use the 90° corner to draw perpendicular lines, the 60° angle for isometric construction and the 30° angle for complementary isometric lines. The calibrated ruler edge can be used for measuring and marking increments directly on the drawing surface. When used in combination with a 45° set square and T-square or parallel ruler, a full range of standard drawing angles can be produced accurately and efficiently.

Store the set square flat or hang via the hole at the top edge to prevent warping and protect the acrylic surface from scratching.
