How much does the Onsrud 145M cost?
Price estimate
We do not have a price for the Onsrud 145M 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 145M is the longest of the standard-width M-Series routers. Table X is 145 in (3,683 mm) and Y is 61 in (1,550 mm), which holds a twelve-foot sheet with clamping margin, and the spindle is the series' 12 hp (8.9 kW), 24,000 rpm unit.
Length is the whole story of this model. It has the same Y, the same 3 vacuum zones and the same 112 in (2,845 mm) machine width as the 121M. What changes is the bed, and with it the machine length of 230 in (5,868 mm).
Buyers comparing it with the 4100M should note that the wider M-Series tables are a different shape of machine. The 4100M offers 83 in (2,109 mm) of Y on a 140 in (3,556 mm) wide frame. The 145M stays narrow, which suits shops that feed long, standard-width panels and want to keep the aisle clear.
Tool capacity is 12 as standard and Z-stroke is 11 in (279 mm). A second and third spindle are listed as upgrades. On a table this long, parking one spindle and using the full bed, which Onsrud describes for larger parts, is a practical way to mix nested small parts with single long ones.

Frequently Asked Questions
01
145 in (3,683 mm) in X by 61 in (1,550 mm) in Y, with 3 vacuum zones as standard. The machine is 230 in (5,868 mm) long, 112 in (2,845 mm) wide and 91 in (2,312 mm) high.
02
No. Table Y is 61 in (1,550 mm). Onsrud's wider M-Series tables, such as the 3100M with 83 in (2,109 mm) of Y, are the ones built for wider sheet formats.
03
The series standard is a 12-tool capacity. Onsrud notes that larger capacity tool changers are optional and lists a 10-position Hide-A-Way changer among the upgrades.
04
Onsrud lists panels of wood, plastic, foam, composites, aluminum and other nonferrous materials for the M-Series. With 12 hp (8.9 kW) at the spindle the machine is aimed at sheet and plate work, not deep cuts in thick block.
