Turning Carbide Insert Holders
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.
S-code holders secure inserts with a screw for easy indexing. They’re the most commonly used holders with positive-rake inserts.
Holders with an offset shank are good for reaching into tight corners and when working close to the chuck.

Precision Carbide Insert Holders for Machining Small Parts
Pair these holders with precision carbide inserts to cut fine details and shape small parts. Designed for use in precision lathes, also called Swiss lathes, they fit directly into a tool holder or post—no tool block needed. All are S-code holders, which means the insert is secured with a screw. They’re the most common holder used with positive-rake inserts. Also known as indexable insert holders.
Choose a holder that matches the insert style and inscribed circle diameter (IC) of your insert. 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. Neutral holders can cut in either direction.

Boring Carbide Insert Holders
Pair these holders with a carbide insert (not included) to enlarge existing holes to precise diameters. They’re made to ANSI standards.
Back-boring holders pass through an existing hole to enlarge it from the back of the workpiece, rather than enlarging the hole as they enter. They're often used to make pipe fittings and hydraulic cylinders.
Face your lathe and use the direction the spindle rotates to choose an insert holder. Use right-hand holders when the spindle of your lathe rotates counterclockwise.
Carbide holders are more rigid than steel holders, so they vibrate less and leave a smoother finish.
Holders with a coolant hole deliver coolant through the holder from your lathe onto the workpiece to minimize heat.

Quick-Change Boring and Turning Cartridges
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 carbide 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.
Back-boring cartridges pass through an existing hole to enlarge it from the back of the workpiece, rather than enlarging the hole as they enter. They are commonly used to make pipe fittings and hydraulic cylinders.
Use right-hand cartridges when the workpiece is rotating counterclockwise, or toward you. Use left-hand cartridges when the workpiece rotates clockwise, or away from you.
Cutting edge angle is also known as lead angle, entering angle, or KAPR.

Quick-Change Boring and Turning Cartridge Holders
A pyramid-shaped shank makes these holders easier to switch in or out of your lathe than round-shank holders. They meet ISO 26623 for compatibility with quick-change systems. Quick-change systems are also known as Capto or PSC. Since these holders form a rigid connection with lathes, they’re often used for precision turning. Rather than removing and replacing an insert while your lathe is stopped, just swap out the cartridge (sold separately) and get right back to work. While one cartridge is in use, you can replace the insert on another, so a fresh cutting tool is always ready to go. Both holders and cartridges have a hole that passes coolant from your lathe onto the workpiece, minimizing heat. Pair the cartridges with carbide inserts.
Use right-hand cartridges when the workpiece is rotating counterclockwise, or toward you. Use left-hand cartridges when the workpiece rotates clockwise, or away from you.
Cutting edge angle is also known as lead angle, entering angle, or KAPR.

While one cartridge is in use, you can replace the insert on another, so a fresh cutting tool is always ready to go.
