HW Z4
T-Slot Cutter
A Klein C173 four-wing HW carbide T-slot cutter with a 41 mm cutter diameter, 3 mm cutting width, 8 mm shank, and 44 mm overall length. The exact C173.030.R Item is listed for compatible hand router machines and router tables working softwood, hardwood, aluminium, plastic, plexiglass, and PVC.
Main Product Description
Klein C173.030.R is the exact 3 mm cutting-width variant in the C173 family of HW Z4 T-slot cutters. The official Item row specifies an 8 mm shank, 41 mm cutter diameter, 3 mm cutting width, and 44 mm overall length.
The four-wing cutter geometry is intended to produce a narrow T-slot profile in compatible material when used in a properly matched hand router or router table. The official family page identifies plastic material and aluminium as primary uses and also lists softwood, hardwood, plexiglass, and PVC among supported workpiece groups.
Correct 8 mm collet fit, cutter clearance, machine guarding, workholding, entry strategy, feed direction, and compliance with the machine and tool speed ratings are essential. Verify that the 41 mm cutter body and 3 mm cutting width suit the intended T-slot geometry before machining.

Confirm the exact C173.030.R Item code rather than selecting by the C173 family alone. Use a clean, compatible 8 mm collet and verify that the router, table opening, guard, fence, and workholding provide safe clearance for the 41 mm cutter body. Confirm the required 3 mm slot width, tool projection, feed direction, material support, and the applicable machine and tool speed limits before use.
