Tile Square - Edge Trim & Jolly Miter Jig – 45 Degree Angle Guide for Saws

Stop struggling with slipping trim and wasted cuts.

Achieving a perfect 45-degree miter on metal tile trim can be the most frustrating part of a bathroom or backsplash install. The metal slides on the wet saw table, the blade grabs it, and suddenly your corner is ruined.

I designed this Tile Trim Miter Jig specifically to solve that problem. Shaped like a framing square for maximum stability, this tool holds Schluter Jolly, pencil trim, and other metal & tile profiles firmly in place, ensuring a clean, safe, and precise cut every time.

Key Features:

8 Colors to choose from!

Zero Slip Design: Holds trim firmly at a locked 45-degree angle.

Multi-Groove System: Features specialized grooves on both the top and front, allowing you to miter from multiple angles depending on your cut direction.

Pencil Trim Ready: Includes a dedicated seating area specifically designed to stabilize round or uneven pencil trims at the correct angle that are usually impossible to hold by hand.

Safety First: Keeps your hands further away from the blade by providing a secure holder for small, sharp metal pieces.

High-Visibility: Printed in bright orange so it’s easy to find in your tool bucket or on a messy job site. Also available in other colors.

Compatibility: Works with most standard wet tile saws. Designed for Schluter Jolly, Rondec, various metal edging profiles, and standard ceramic/stone pencil liners.

How to Use:

Place the jig against the back edge of the sliding tray on your tile saw.

Nest your trim piece into the appropriate groove (top or front).

Push the tray with the jig and trim together through the blade for a perfect miter.

Note: This item is 3D printed with durable materials intended for job site use, but like all tools, should be used with care around power equipment.
