CAPTO tool holder Jetstream Tooling® M-Clamp

millingcustom-madewith coolant

Product overview
Jetstream Tooling® M-Clamp toolholders incorporate high-pressure coolant channels directly into the toolbody. Coolant flows through the 3D-printed coolant clamp with an additional flank outlet (DUO JET), providing targeted coolant at the cutting zone for larger inserts. The result is longer tool life, improved chip control and better surface finishes when machining hard-to-cut materials like stainless steels and superalloys.

Optimized coolant flow with 3D printed clamp
Our additive-manufactured (AM) coolant clamp is positioned at a safe distance from the cutting edge to deliver high-pressure coolant precisely where needed. The AM clamp design maximizes tool life, improves surface finish and provides better chip control at high cutting depths. The clamp’s robust construction resists chip hammering, reducing clamp wear and instability.

Double security for both negative and positive inserts
The JETI M-Clamp toolholders provide double clamping security for negative inserts and round positive inserts by combining a top clamp with a center-lock screw. This increases insert stability and rotational security, lowering the chance of movement and improving reliability under demanding machining conditions.

Faster insert changes with twist function and smart indexing
The JETI M-Clamp uses the same key size for both the clamp and the insert screw. The twist function of the top clamp allows it to be rotated away for easier insert indexing, reducing setup time and minimizing downtime during high-volume machining.

Proven increase in tool life of 30% or more
Depending on the application, the high-pressure Jetstream Tooling® solution typically delivers at least a 30% increase in tool life compared to standard fluid coolant systems, resulting in fewer tool changes, reduced costs and higher productivity.

Customize your own clamp
Thanks to 3D printing, AM clamps can be customized to meet specific requirements and unique machining challenges, offering adaptability that traditional clamps cannot match.
