Seco 00043225 Indexable Boring Bar 1 in Shank Right Hand

Product Description

The SECO 00043225 is an indexable boring bar designed for precision internal boring and turning operations on CNC lathes and manual turning centers. Built from steel with an MWLN toolholder style, this bar accepts WNMG 432 trigon inserts held in place by a pin and clamp mechanism for reliable, repeatable cutting performance. Key dimensional specs include a 1.28-inch minimum bore diameter, a 1-inch shank diameter, a 12-inch overall length, and a -5 degree lead angle. The negative rake geometry at -14 degrees suits heavy interrupted cuts and hard materials. This tool is specified and installed by machinists and tooling setup technicians in production and job-shop environments.

This boring bar is suited for both boring and turning applications in residential shop, commercial machine shop, and production floor settings. The 0.64-inch center-to-cutting-edge measurement and 0.5-inch insert inscribed circle support accurate depth-of-cut planning. The right-hand cut orientation makes it compatible with standard forward-feed turning setups. Its 12-inch overall length provides reach for deeper bores while the 1-inch shank ensures rigid clamping in standard boring bar holders and quick-change toolposts.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the tool turret or toolpost is locked before mounting or indexing inserts. Clamp the 1-inch shank securely in the boring bar holder with adequate stick-out minimized to reduce chatter. Follow the machine tool manufacturer guidelines and your facility safety procedures when setting tool offsets and running initial test cuts.
