How much does the Onsrud 121M cost?
Price estimate
We do not have a price for the Onsrud 121M that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.
Overview
The Onsrud 121M is the mid-size M-Series router with the narrower gantry: a table of 121 in (3,074 mm) by 61 in (1,550 mm) under a 12 hp (8.9 kW), 24,000 rpm spindle. It is the shortest table in the series that has the full 61 in of Y and 3 vacuum zones.
Compared with the 97M the step is mostly about width and zoning: Y grows from the 49 in (1,245 mm) of the 97M to 61 in (1,550 mm), and the single zone becomes 3. The cost in floor space is modest: 207 in (5,258 mm) of length and 112 in (2,845 mm) of width, at the same 91 in (2,312 mm) height.
The 145M uses the same gantry width and adds table length only. So the choice between them comes down to the longest sheet the shop runs. If that is a ten-foot panel, the 121M holds it with almost no table left over, which keeps the operator's reach short.
Standard tool capacity is 12, with larger changers optional. Z-stroke is 11 in (279 mm). The series can take up to 3 spindles as an upgrade, and the standard control is a touchscreen FANUC unit.

Frequently Asked Questions
01
121 in (3,074 mm) in X and 61 in (1,550 mm) in Y, divided into 3 vacuum zones as standard. The machine around it is 207 in (5,258 mm) long, 112 in (2,845 mm) wide and 91 in (2,312 mm) high.
02
They share the 61 in (1,550 mm) table width, the spindle and the 3 vacuum zones. The 145M has a table X of 145 in (3,683 mm) and a machine length of 230 in (5,868 mm). Pick by the longest sheet you need to lay flat.
03
A 12 hp (8.9 kW) spindle with a top speed of 24,000 rpm. The M-Series upgrade list offers additional spindles, up to 3 in total, but shows no higher-power motor.
04
11 in (279 mm). That figure is the stroke of the axis, so usable clearance under the tool depends on tool length, spoilboard thickness and any fixture on the table.
