What adjustment does the micro-adjust collet provide?
One full revolution of the collet advances or retracts the wheel 1/32". A half turn moves it 1/64", and a quarter turn moves it 1/128".
Use as a depth gauge to transfer measurements.

Our standard wheel marking gauge is a great workhorse and excellent value. Its popularity led to the development of a second model that incorporates a micro-adjust feature. It is similar to our standard wheel marking gauge with an anodized aluminum body, brass face, stainless-steel rod and internal O-ring to keep a constant light friction force on the rod. It differs in that the body is slightly longer and is fitted with a two-stage collet that allows micro-adjustment of the cutting wheel. The collet has a fine-pitch thread; one revolution advances or retracts the wheel 1/32", a half turn 1/64", a quarter turn 1/128", etc. The knurled thumbscrew then locks the setting.
The hardened steel wheel cuts wood fibers rather than tears them, which leaves a clean mark, even on cross grain. The wheel’s single-sided bevel also forces the gauge face against the stock, maintaining accuracy. The cutting edge of the wheel is at the extreme end of the shaft, which is useful for transferring dimensions such as tenon shoulder or mortise depth. The wheel retracts into the face of the gauge for storage.
The gauge is available with either an unmarked rod or a graduated rod. The rod of the Imperial gauge is graduated to 6" in 16ths; the metric version has graduations to 150mm. Patented.

The standard wheel marking gauge uses an O-ring for friction and a thumbscrew to lock the rod position. The micro-adjust version adds a two-stage collet with a fine-pitch thread so the wheel can be moved in precise increments — 1/32" per revolution — before locking.
All three versions use the same gauge body, O-ring friction system and micro-adjust collet mechanism. The standard rod is unmarked. The graduated imperial rod reads to 6". The graduated metric version reads to 150 mm.
