A digital depth gauge for workshop use that delivers precise depth and height readings, the Smgda 80mm Digital Depth Gauge. Clear numeric readouts and easy setting changes make cutter adjustments quicker and less stressful. Is the build up to repeated workshop use and regular measuring tasks?
⚡ At a Glance
- • Measurement Accuracy: Range 0-80mm (0-3 inch) with 0.1 mm / 0.01 in resolution
- • Best for: Woodworkers, DIYers and router/table saw users needing fast depth checks
- • Not ideal for: Metrology labs or heavy industrial use requiring metal gauges
Compact digital gauge measuring 0 to 80mm with fine resolution. Suited to woodworking, router and table saw depth checks.
Quick, readable measurements - with a large LCD and unit switching
A large LCD shows numeric readings clearly and a unit switch toggles between millimetres and inches. Removable measuring rod design keeps the measuring length flexible.
Fast visual feedback reduces setup time at the bench and helps avoid misreads when setting cutter depth.
Hands-free positioning for stable setups - with a magnetic base and flat back
Magnetic base secures onto ferrous surfaces while a flat back lets the tool sit vertically or horizontally. Zero can be set at any point along the slide scale for reference measurements.
Stable placement allows single-handed tool adjustments and safer, more repeatable cutter height settings.
Lock and hold readings for repeatable cuts - with a knob-locked data hold function
A knob-locked one-key data hold freezes the displayed value so the reading cannot drift while transferring settings. An adjustable back supports self-standing use when required.
Locked readings make it easy to copy settings across machines or repeat identical cuts without re-measuring.
✨ The 4 Key Reasons for Smgda 80mm Digital Depth Gauge
