METHOD OF INSERTION & RELEASE FOR RD/ER COLLETS

INSERTING

  1. Insert collet into nut at angle as shown to engage extraction tongue in groove of collet.
  2. Screw nut onto collet holder with collet securely in nut
  3. Insert tool to be gripped and lock nut.

IMPORTANT: Never screw nut onto collet unless collet is properly seated in nut.

RELEASING

Hold nut in vertical position and remove nut at an angle. Collet is automatically withdrawn from chuck by excentric ring of nut when unscrewed.

INTERNAL & EXTERNAL COOLANT COLLETS

Sealed for coolant-through applications, with pressure resistance tested to 1000 p.s.i. Sealed collets are high precision exact size collets and have no collapse range.

Internal Coolant Collets (IK): To direct fluid through the cutting tool.

External Coolant Collets (EK): To direct fluid through the collet to the cutting tool tip, allowing the use of standard cutting tools in coolant through applications or to route fluid through the tool and around the tool for higher coolant volume.

ND COLLETS

Nominal size collets manufactured per DIN 6499 Form A are available in inch and metric sizes by special order, offering maximum 0.0003 in. TIR.

TAPPING COLLETS

RTS Rigid Tapping Collets
with Square Drive

For synchronous tapping operations using any RD/ER collet chuck. Collet bore is exact tool diameter, with square drive, for accuracy and rigidity. Available sealed for coolant-through applications, as well as in DIN and JIS standard metric sizes.

RDT Quick-Change
Tapping Collets
with Axial Compensation

For use with any RD/ER collet chuck, these tapping collets help prevent tap breakage on machines requiring axial compensation. Friction-free ball-bearing drive. Metric sizes available upon request.

A = 33 mm. (1.23 in.)
B = 40 mm. (1.58 in.)
Collapse per collet: 1 mm. (0.039 in.)
Capacity per set: 1 – 20 mm. (0.079 – 0.787 in.)
Precision per DIN 6499
Maximum tightening torque: 80 ft./lbs.

INTERNAL & EXTERNAL COOLANT COLLETS

Sealed for coolant-through applications, with pressure resistance tested to 1000 p.s.i. Sealed collets are high precision exact size collets and have no collapse range.

Internal Coolant Collets (IK): To direct fluid through the cutting tool.

External Coolant Collets (EK): To direct fluid through the collet to the cutting tool tip, allowing the use of standard cutting tools in coolant through applications or to route fluid through the tool and around the tool for higher coolant volume.

ND COLLETS

Nominal size collets manufactured per DIN 6499 Form A are available in inch and metric sizes by special order, offering maximum 0.0003 in. TIR.

TAPPING COLLETS

RTS Rigid Tapping Collets

RD/ER 40 INTERNAL & EXTERNAL COOLANT COLLETS

Sealed for coolant-through applications, with pressure resistance tested to 1000 p.s.i. Sealed collets are high precision exact size collets and have no collapse range.

Internal Coolant Collets (IK): To direct fluid through the cutting tool.

External Coolant Collets (EK): To direct fluid through the collet to the cutting tool tip, allowing the use of standard cutting tools in coolant through applications or to route fluid through the tool and around the tool for higher coolant volume.
