Secure carbide inserts inside these holders for stable turning. They’re also known as indexable insert holders. Select a holder that’s compatible with your insert by matching the insert style and inscribed circle diameter (IC). Right-hand holders move from right to left toward the lathe chuck, left-hand holders move from left to right away from the lathe chuck, and neutral holders can cut in either direction.

Pair these holders with a carbide insert (not included) to enlarge existing holes to precise diameters. They’re made to ANSI standards. Face your lathe and use the direction the spindle rotates to choose an insert holder.

Limit downtime when you’re changing out cutting tools. Rather than removing and replacing an insert while your lathe is stopped, just swap out these cartridges and get right back to work. While one cartridge is in use, you can replace the insert in another, so a fresh cutting tool is always ready to go.

Pair these cartridges with a lathe tool insert and connect them to your lathe with either a quick-change cartridge holder or boring bar (each sold separately). Cartridge holders mount to quick-change lathe systems, also known as Capto, while boring bars mount with round shank toolholders. All components are coolant-through compatible. They have a hole that delivers coolant from your lathe onto the workpiece to minimize heat.
