End Mill Holder and Runout

As a general rule most cutting tool & end mill manufacturers prefer to use single angle (ER/DR style) collet chucks for most cutting tool holding applications under 1/2". Why? Runout and uneven chip load. This is because of two reasons:

• The error accumulation on ID tolerance of the end mill holder and the OD shank tolerance of the end mill or drill. The smaller the diameter the more potential for problems...
• The imbalance created in the toolholder by the setscrew used to clamp the tool. When you tighten down the setscrew you not only offset the tool but also create an imbalance condition that is not repeatable due to the ANSI shank tolerance on all end mills.

Depending on the application, end mill holders can be used for holding larger insert style end mills, spade drills, etc.  But somewhere between 1/2” and 3/4” there is a line that only you can determine when you need to move from a collet chuck to end mill holder. Generally we recommend using end mill holders only for very specific applications

Using small diameter end mills (1/4" and below) in end mill holders with set screws will have a adverse affect of both surface finish and tool life.  

"The most important thing to say about toolholders in high speed milling of aluminum,” said Dr. Sinan Badrawy, formerly of Cincinnati Machine in a 2001 article “is not to use a set-screw holder.” Because the set screw moves the end mill off center to hold it against the wall opposite the set screw, it creates run-out.  “At high speeds, at set-screw holder will chatter no matter what,” he said.  The better choice are collet holders and shrink fit holders. Both do clamp the tool from all directions around the shank.”

Super-Charge Your #CNC ToolHolders with Shrink-fit Extensions

Shrink Fit extensions fit into any toolholder

TechniksUSA Shrink Fit Extensions

Get the most out of your tool holders by adding shrink-fit extensions to your tool crib. These handy extensions add shrink-fit capability and reach without the expense of buying dedicated shrink-fit toolholders. They work great with Techniks'low-cost induction heat shrink machine the TechnoSHRINK 2.

Shrink fit extensions are used with most types of tool holders including: collet chucks, shrink-fit holders, hydraulic chucks, milling chucks, end mill holders, etc. They hold cutting tool shank sizes of: 1/8", 3/16", 1/4", 3/8", 1/2", and 5/8".

Features:

• More rigid and better T.I.R. than collet extensions 
• Extended reach and slim design fits tight clearances 
• Works with your existing tool holder inventory

Benefits: 

• Lower cost than any other shrink fit system! 
• Improved rigidity makes carbide cutting tools last longer 
• Eliminates purchasing dedicated shrink-fit tool holders

CoolFlex Toolholders have Multiple Coolant Paths

CoolFLEX collet chucks and end mill holders feature a coolant path that can be switched from coolant-through-spindle to DIN style coolant simply by removing two setscrews.    

Now you don't have to buy machine-specific toolholders!

This feature can save thousands of dollars when compared to the cost of tooling-up both coolant- through and DIN coolant spindles.

CoolFlex holders are available for CAT40 and CAT50 spindles, in ER collet chuck and End Mill holder styles. The collet chucks are available in sizes in ER16, ER20, ER25, ER32 & ER40 and are balanced to 18,000 RPM. The end mill holder styles range from ID 1/4” to ID 1-1/4” and are balanced to 10,000 RPM.

All CoolFlex holders are factory set for the coolant-through-spindle application and can be changed to DIN style by the user. CoolFlex collet chucks come with Techniks’ “Power Coat” nut that increases clamping power on the tool shank up to 75%.
