Crossing a LMT Onsrud tool to RobbJack

There's no universal part-number standard across cutting-tool brands, so we match on what actually determines performance: cutting diameter, flute count, end type and corner radius, length of cut, work material, and coating. Enter your LMT Onsrud part number and we'll look up those specs automatically — or type in what you know. RobbJack matches your size to its nearest standard (for example RobbJack's .030 corner radius for a .031), and you can require an exact match or allow a near-size upgrade.

Don't see a match? RobbJack builds a huge range of specials. Send us the LMT Onsrud part number and our application engineers will cross-reference it directly — often a longer-lasting, faster-cutting upgrade, not just a like-for-like swap. LMT Onsrud is a trademark of its owner; RobbJack is not affiliated with LMT Onsrud, and cross-references are for identification only.
