Collets (DIN 6499)
A collet is used to hold small diameter workpieces and small diameter milling cutters. Collets normally accept material that is .001 inches over the collet size and .004 inches under the collet size. We manufacture collets of standard sizes listed below and the sizes according to the customers requirements

Advantages of Collets
The advantages of Gem Collets are:
- Tools can be loaded quickly
- Collets are very accurate
- Maximum spindle speeds can be used
- Compatible with all vertical machining centers and vertical milling machines
Benefits of Collets
The benefits of Gem Collets are:
Vibration Dampening
- One of the benefits realized from a high-speed collet system is vibration dampening. The collet toolholder’s vibration dampening yields many benefits including longer tool life, superior surface finish and less wear on the spindle—thereby increasing its life.
Accurate finish
- Gem Collet have a flat shoulder design for heightened perpendicular force transfer, which eliminates the potential for twisting of the collet that can thereby add inaccuracies as it is tightened.
High speed
- High-performance collet toolholder is balanced for operating at up to 40,000 rpm, allowing it to offer the ultimate in high speed, high accuracy and ultra smooth surface finishes.
Applications
- The Gem collets are quick, clamp on a high percentage of the part surface, they don't have pressure points and they run very concentrically
- Ideal for batch production of secondary operations using multiple spindles or in shops for prototyping
- Collets allows a small part to be extended well into the cutting area, avoiding the potential for interference with the tooling or spindle nose
