Machining accessory that locates workpiece edges quickly and accurately for milling and lathe setups. Saves setup time and reduces the risk of misaligned cuts for hobbyists and professional machinists. Is the Jectse Mechanical Edge Finder the right choice for precise, repeatable workshop setups?

⚡ At a Glance
  • Measurement Precision: Repeated measurement accuracy within 0.005mm
  • Best for: Machinists and hobbyists using traditional milling machines and comprehensive processing machines
  • Not ideal for: Users who require electronic or digital readout probing systems

Mechanical rotary measurement uses a spring-loaded probe that minimises clamping error. A 4mm probe and anti-magnetic lower rotary section help locate narrow grooves and small apertures reliably.


Sub-0.005mm repeatability, thanks to mechanical rotary measurement

Mechanical rotary measurement relies on a spring-mounted centre that disengages once the touch point is reached, eliminating clamping-induced offsets. Repeated measurement accuracy is specified to reach within 0.005mm.

Consistent edge locating speeds up setup and reduces trial cuts when aligning workpieces for precision milling.

Access to tight spaces, with a specially designed 4mm probe

A dedicated 4mm probe on the lower end is sized for small apertures and narrow grooves, enabling contact within confined features. The probe works with the rotary measurement to register touch points reliably.

Makes it practical to set up parts with small features without swapping tools or improvising with makeshift probes.

Durable workshop use, with carbon steel construction and anti-magnetic rotary lower end

Carbon steel material gives the tool resilience against knocks and regular bench use, while an anti-magnetic design on the rotary lower end prevents magnetic interference during rotation. Recommended operating speed is within 400–600 rpm.

Robust construction suits frequent use in busy workshops, maintaining accuracy and service life under normal machining conditions.

✨ The 4 Key Reasons for Jectse Mechanical Edge Finder
  1. Dual-end sizes (20mm & 10mm) - Allows reaching both broad and narrow edges without swapping tools
  2. 4mm probe - Enables measurement inside small apertures and narrow grooves
  3. Carbon steel construction - Resists workshop knocks for longer service life
  4. Designed for 400–600rpm use - Matches common manual milling spindle speeds
