Why Choose AutomTool
Automated Precision Tool Length Calibration for UK Machinists
Eliminate tedious paper zeroing and eliminate expensive cutter breakage with the Hongyang CNC tool setting probe. Engineered specifically for precision milling machines, CNC engraving machine tool setters, and routing tables, this high-accuracy Z-axis touch sensor provides automated offset calculations with micro-inch repeatability (<0.002mm). Whether you are running multi-tool G-code programs or executing delicate PCB isolation routing, this sensor delivers consistent zero-point accuracy every single run.
Fail-Safe 4-Wire Normally Closed (NC) Over-Travel Protection
Unlike basic 2-wire DIY touch plates that rely on simple electrical grounding, this normally closed tool setter incorporates a dedicated dual-circuit microswitch mechanism. The primary contact trigger registers the tool tip height, while the secondary over-travel circuit acts as an emergency stop (E-stop limit switch). If your Z-axis over-shoots due to software lag or improper speed settings, the safety signal instantly halts spindle movement, protecting your micro carbide bits and machine bed from catastrophic crashes.
Industrial IP67 Sealing for Harsh Machining Environments
Designed for real-world workshop conditions, the heavy-duty housing features double-layer rubber seals and an oil-resistant nitrile boot. The IP67 rating ensures that liquid flood coolant, cutting fluids, cast iron dust, and aluminum swarf cannot breach the internal optics or contact switch. Complete with a polished tungsten carbide surface (hardness HRC90+), this unit withstands millions of probe cycles without surface wear or calibration drift.

Customer Reviews
Transformed the workflow in my engineering shop. Tool length offsets in Mach3 used to take 10 minutes of manual feeler gauge zeroing; now it takes 5 seconds per tool with sub-micron accuracy. The 4-wire NC setup gave me peace of mind against spindle crashes.
As a precision model maker working with 0.3mm carbide end mills, zeroing Z height manually was always risky. This Hongyang touch probe has 0.0018mm measured repeatability on my mill. Haven't snapped a micro bit since installing it!
Solid build quality. The IP67 fluid seal holds up perfectly under heavy flood coolant while machining stainless steel. Wiring diagram included in the UK dispatch box was crystal clear.
Excellent cnc z axis probe for the money compared to £600+ industrial alternatives. Cable length is generous (2 metres). Only minor point is you need to make sure the face is totally clean of chips before running precision routines.
Fitted to my LinuxCNC custom router table. Automated tool changes are now effortless. The over-travel circuit saved my spindle bed when I misconfigured my probing speed parameter!
Fast next-day delivery to my workshop in Leicester. The tungsten carbide face shows zero signs of wear after hundreds of probe contacts. Highly recommended UK supplier.
Very responsive sensor switch with impressive zero-point repeatability. It took me 20 minutes to wire up to my GRBL expansion board, but works like a charm now.
