How SK Live Tools Eliminate Cutter Pullout and Improve Machining Performance

Friday, September 26, 2025

Some common challenges manufacturers face with live tools is high runout or pulling out of cutting tools ruining a workpiece. SK live tools can solve these challenges due to higher gripping force, ability to machine with higher chip loads, and reduced cycle times.

Live tools can have an ICE (Internal Coolant + External Option) feature that allows internal coolant live tools to run dry continuously.

A graphic titled Benefits of Higher Gripping Force lists machining advantages and torque specs, with a black technical illustration of a tool and text detailing tightening torque, collet size, and pin specifications.

Watch the video to learn the difference between SK ICE live tools from traditional SK live tools:

There are three key benefits of using SK ICE live tools instead of traditional live tools:

  1. Higher Gripping Force – You can machine with higher chip loads and reduce cycle time with better cutting conditions; additionally, eliminates over tightening that leads to collet damage and excessive runout while reducing end mill pullout and scrap parts.
  2. Greater Rigidity, Precision, and Clearance – The longer and slimmer 8° taper SK collet allows for a smaller body diameter enabling working closer to the chuck that gives greater rigidity, precision, and clearance.
  3. Run With or Without Coolant – SK ICE live tools are designed to run with or without coolant through the live tool, allowing them to run dry without breaking. It is easy to change between coolant set ups and can be used in a variety of applications without changing out tooling – allowing for minimal downtime.

When comparing the results of SK live tools to ER live tools, SK live tools consistently outperform ER live tools. See the difference between machining with ER live tools versus SK live tools in this test cut demo video:

Bottom line is when using an ER32 Z axis or X axis live tool, the tool starts pulling out during machining or breaks. On the other hand, using the SK 20 Z axis or X axis live tool machining the same cut as the ER live tool – the SK live tool plows right through and completes the cut with no issues, no cutter pull out, and the tool does NOT break.
