Collet Chucks and Collets

For over 100 years, Crawford Collets has been renowned and respectedaround the world for quality products at competitive prices.

As technology advances in the world of machine tools, Crawford have continually strived toimprove the workholding methods required for accurate and cost effective machining. Crawford now offer the ultimate in collet chucking systems to suit most machining applications.

The range of collet chucks are manufactured to the highest standards with concentricitiesbetween the rear register mounting and the working collet taper to within 0.005mm TIR.

The comprehensive range of Crawford drawbar chucks has been designed & developedspecifically for use on CNC turning machines.

Short Body which accepts Crawford Multibores, also available with a quick change closing cap version for both Crawford Multibores and DIN 6343 Multibores.

Standard Body which accepts either style of Multibore, but alsoaccepts Spring Collets to enable accurate 2nd operation machining, also available with a quick change closing cap.

Extended Body which accommodates certain machines longerdrawtube standout. This collet chuck accepts either type of Multibore or Spring Collets.

The CNC range of chucks is available in three different lengths:

This complete range is available in a wide variety of capacities and spindle mountings.


A new addition to our range is the DMC Drawback Collet Chuck, which was developed foruse with a drawback action to ensure positive location against the feed ram, thus eliminatingfeed length variations. Short Body accepts either Crawford Multibores or the DIN 6343Multibores with a variety of capacities and spindle mountings.

Table mounted chuck was designed to be completely self-contained which enables it to beespecially suitable for cubotic machining centres. Its unique design also enables full rotationfor NC rotary table applications.

To complement the existing range, Crawford now offer Collet Chucks which accommodateboth the 5C and 16C Spring Collets, thus enabling their utilization on CNC turning machines.

Pullback Collet Chucks accept either 5C or 16C Collets in a variety of spindle mountings.

Deadlength Collet Chucks accept either 5C or 16C Collets in a variety of spindle mountings. A special ‘Setrite’ facility can be provided, which enables the user to improve the colletconcentricity to virtual zero.

Our range of manual collet chucks, include the ever popular Trugrip Chucks, which can befitted directly for turning, milling and grinding operations to an accuracy of 0.015mm TIR at the face.

The Trugrip Chucks accept either the 5C or 16C Collets in a variety of spindle mountings.

Our latest development, features a Pneumatic front mounted Deadlength Collet chuck which can be fitted directly for turning, milling and grinding operations to an accuracy of0.025mm TIR at the face.

The Pneumatic Chucks accept either 5C or 16C or 173E Spring Collets in a variety of spindle mountings.
