Solid aluminium step depth gauge for setting blade height and router bit depth. Laser-engraved markings and premade dovetail guides aid repeatable, workshop-ready measurements.


Repeatable dovetail joints - With premade convex and concave guides

Premade convex and concave templates control the positioning of the teeth and the milling cutter, registering consistent dovetail dimensions across multiple cuts.

Consistent joint sizing reduces wasted material and speeds up production of drawers, boxes and matched furniture parts.

Clear readings after heavy use - With laser-engraved aluminium markings

Laser engraving embeds scale markings into aluminium, so numerals and ticks resist abrasion from handling and sawdust.

Quick, reliable visual checks shorten setup time and avoid repeated small adjustments during long projects.

Work in metric or imperial - With front metric and back imperial scales

Front scale lists common millimetre steps used in furniture making, while the rear side shows common fractional inch measures for legacy plans.

Seamless switching between scales suits workshops following different plans without manual conversion.

✨ The 4 Key Reasons for CDIYTOOL Step Depth Gauge
  1. Dovetail guides - Enable consistent dovetail joint sizing across multiple workpieces
  2. Front metric scale - Quickly set bit depth to common furniture-making sizes
  3. Imperial rear scale - Accommodates imperial plans, avoiding manual conversion and mistakes
  4. Solid aluminium construction - Resists wear and keeps markings legible over years
