High Speed operations require a performance tool.
What good is balancing an ER collet chuck to 25,000 RPM's when a standard collet runs out 0.0004"?  Doesn't that defeat the purpose of High Speed Tooling?

PIONEER Premium SX System standard TIR is 0.0002"
with optional 0.0001" on demand.
Higher Performance due to a Better Design

Design difference #1 - Shown: SX06 vs ER11
    SX06 has a 8 degree included taper
    ER11 has a 16 degree included taper
Results: 1/2 the taper = 40% higher locking torque

Design difference #2
    SX taper length is 25% longer than ER
Results: More engagement for greater support and rigidity.

Design difference #3
    SX locks on a square surface, ER locks on a taper
Results: If the nut is not on the same center-line as the chuck, the nut will move the nose of the collet off center causing additional TIR.
Overall Results: 20-50% better tool life than ER.  

Need additional Clearance?  Try MX!
MX06 is a 1/4 capacity system with a nose diameter of 1/2" or less.  MX standard TIR is 0.0001"!

PIONEER's updated BT30 SX and MX products are pre-balanced to G2.5 @ 25,000 RPM's with certifications in the box!

Milling with ER Collet Chucks
SX "A" Type Collets provides
Superior Milling Performance over ER


Milling with a collet chuck is all about
Radial Support and Runout.  
SX Collets set deeper in the pocket,
provide 1/2 the TIR of ER,
 
resulting in superior performance.

The picture below shows ER and SX collet chucks and how much far collet is setting out of the body in a locked position on a 1/2 End Mill.
Shown: 1/2 End Mill in ER32 vs SX16-A 

Why SX?
  • More surface engagement for superior support
  • SX 8 Degree Collet Taper supplies 2 lbs of locking pressure for every 1 lbs of locking torque, ER is 1:1
  • 1/2 the TIR of standard ER Collets 
    SX Collets 0.0002" TIR @ 4 times tool diameter Standard!
  • Square Locking Shoulder 
    - the nut cannot influence TIR
  • Slim Nose Design
  • Dynamically Balanced G2.5 @ 20,000 RPM 
    (Cat50 @ 15,000 RPM)
SX collets come in 2 styles, A Type and B Type:
  • A Type
    • Designed for h6 qualified shanks 
    • Best for Milling!
  • B Type
    • Designed for 0.020 (0.5mm) collapse range 
    • Best for Drilling & Reaming!
Guaranteed Performance
SX will out perform any standard ER collet chuck or your money back!

Why SX instead of ER?
This question is common with end users and distributors.  
It is simply performance.
This picture shows a CAT40 SX10 Collet Chuck with a 6.5mm collet holding a 1/4 (.250) gage pin.  
TIR at 10 times Diameter, 
2.5" was 0.0003" (8 microns).

Standard grade collet from inventory 
collapsing down 6.50 to 6.35 
providing TIR ER cannot get close to!

TIR matters at the end of your tool not the front of the collet, SX provides the TIR you need for greater tool life, more consistent production and lower your tooling cost.

Using standard specifications...
The numbers shown above are projected TIR in a "worst case" scenario.  
If you purchased an ER collet and it was checking 0.0004" @ 2 times diameter, projected TIR at 10 times diameter would be 0.0020".

In the same scenario, SX collet checking 0.0002" @ 4 times diameter, projected TIR at 10 times diameter would be 0.0005" and average under 0.0004".
