Features:
- Left-hand and right-hand variants available
- Optional “U-Type” tool holders are compatible with “U-Type” thread turning inserts
- Most tool holders are made with a 1.5° helix angle. For other angles, please consult the helix angle chart.
OFF-SET (OFFSET) HOLDERS
Tool holders for offset turning, a type of turning in which the central work axis doesn’t align with the headstock spindle.
EXTERNAL HOLDERS WITH TOP CLAMP
External tool holders for turning inserts. These holders have an additional clamp for extra insert fastening security.
Features:
- Left-hand and right-hand variants available
- Most tool holders are made with a 1.5° helix angle. For other angles, please consult the helix angle chart.
Notes:
- Two clamping methods can be used: Screw / Top Clamp
- For DER 2525 M22 and DER 1000 M22, use the K21 torx key for C22 clamp
EXTERNAL VERTICAL HOLDERS
Tool holders for external, vertical style thread turning jobs.
Notes:
- These tool holders can only be used with vertical thread turning inserts – either partial profile, or full profile.
SLIM THROAT HOLDERS
Tool holders for external, vertical style thread turning jobs. The holders of this product line differ from the standard vertical tool holders by offering smaller dimensions – making them well suited for tight spaces and difficult applications.
Notes:
- These tool holders can only be used with vertical thread turning inserts – either partial profile, or full profile.
DROPHEAD HOLDERS
Tool holders for cutting external threads/grooves. These holders are specially designed to operate in an upside-down position, while keeping the height of the cutting edge at the same level as standard tool holders.
GANG HOLDERS
The gang tool holders are external holders, which are used in small automatic machines equipped with a gang-style tooling post.
Features:
- Left-hand and right-hand variants available
X-TREAM JET (EXTERNAL HOLDERS WITH INTERNAL COOLANT)
A unique product line of external tool holders equipped with an internal coolant – enabling a flow of coolant to the cutting edge. This reduces the temperature of the cutting edge while machining, helping to extend the life span of the tool. Additionally, the coolant fluid aids in removal of the chips during operation – improving the cutting performance.
Features:
- Two coolant connectors (using elbow fittings)
- Available with either ø4 mm or ø6 mm (the default) connectors
- Left-hand and right-hand variants available
- Coated holders provide abrasion resistance
- Tool holders are made with a 1.5° helix angle. For other angles, please consult the helix angle chart.

HOLDERS WITH 3.5° HELIX ANGLE
Tool holders for internal turning jobs. Unlike the standard holders that use a 1.5° helix angle, the tool holders that belong to the current product line use 3.5°.
Typically, one would consider using such a tool holder in case of a large-pitch thread with a relatively small diameter.
HOLDERS FOR SPECIAL APPLICATIONS
The tool holders in this line of products are all optimized for one specific thread. Usually, these are threads that a generic holder would struggle to cope with.
