Speed Square 7inch metric drill gauge
Product description
Key points
A compact aluminium alloy speed square that combines a metric ruler and a drill gauge for everyday carpentry tasks. The tool integrates 14 drill holes ranging from 3mm to 15mm, a widened T-shaped base for edge stability and laser-engraved metric markings on a 180mm edge. It suits quick marking, drilling positioning and squaring work, and its 200g weight makes it easy to hold for extended use. The main long-tail search term "7inch metric triangle ruler" appears naturally for users seeking a small, precise layout tool.

Benefits
The alloy body resists deformation so accuracy lasts longer under typical site conditions. The laser-engraved markings stay legible through frequent use according to the manufacturer details, and the T-shaped base reduces slippage when you butt the square against timber edges. There is a practical balance between lightness and rigidity, which helps with one-handed marking and repeated positioning.
How to use it
Hold the widened T base flush against the board edge to draw 90° lines or to mark cut lines, then select the matching drill hole and use it as a quick centre punch guide before drilling. It’s useful for setting up screw positions and checking verticals when building frames or fitting fixtures. It’s a good fit if you work with metric fasteners and need a compact, multipurpose layout tool, and it makes sense if you favour a tool that combines ruler and drill gauge in one piece.
