Indexing Collet Fixtures
Used with a 5C collet (sold separately), these fixtures rotate round, hex, or square workpieces up to 1 1/8" diameter in precise increments. Also known as spindexers or punch formers, they are commonly used to drill holes into cylindrical parts, grind punches into precision shapes, and sharpen drill bits and end mills. To ensure accurate rotation, spindles are precision ground. Mount fixtures to a machine table for horizontal orientation or an angle plate for vertical. A through-hole accommodates long workpieces.
Fixtures with 1° index increments have an indexing plate with 36 holes for rotating in 10° steps and 10 additional holes for 1° refinements. Fixtures with 15° index increments have 24 locking positions.
High-Density Air/Hydraulic-Operated Collet Fixtures
Use multiple fixtures to create a workholding system capable of clamping and unclamping multiple parts with the push of a button. When powered hydraulically, these fixtures exert five times the force of standard air-operated collet fixtures, making them good for heavy machining requiring an extra-tight hold. Used with air, they provide the same holding power as standard fixtures. Maximum clamping force depends on the pressure of your system. To calculate the clamping force on your collet, multiply inlet pressure by 7.5. Use 5C collets (sold separately) to grip and release parts on milling machines and drill presses. During clamping, the collet remains stationary to ensure the workpiece does too. A through-hole on the bottom of the fixture accommodates long workpieces.
Connector bushings join multiple fixtures. Two connectors are needed for each fixture after the first.

Lathe Chuck to 5C Collet Adapters
When a job calls for a 5C collet, save time by using an adapter instead of removing your lathe chuck. The adapter fits most lathe chucks. Install a 5C collet into the adapter and secure it by turning the lock with the included hex key.

5C Collet to Lathe Chuck Adapters
No need to break down a collet set up when a workpiece doesn't fit a 5C collet. Install one of these lathe chuck adapters in your 5C collet chuck or holder and its three jaws will securely grasp the workpiece. These chuck adapters are self centering—all three jaws move in unison, centering the workpiece as they close. Use the included lathe chuck wrench to open and close the jaws.

5C Collet Block Chucks
Install a 5C collet into one of these chucks to hold a workpiece for machining parallel or square edges and drilling crossholes. The included tightening ring closes and opens the collet.
Optional lever collet closer works with the tightening ring for faster closing and opening.
Quick-Change Tool Holders for Milling Machines
After installing the R8 body in the milling machine spindle, tool holders can be switched out in seconds. To remove a tool holder, depress the brass locking button and rotate the collar on the R8 body. When a new tool holder is inserted, a spring-loaded pin snaps the collar back into the locked position.

Retention Knobs
Attach tool holders such as collet chucks and end mill holders to your CNC machine’s spindle. For proper operation, choose a knob that exactly matches your collet type and spindle dimensions. All meet industrial standards for tensile and shear strength. These knobs are also known as pull studs.
Knobs with a coolant hole let coolant flow through to protect your tools and workpiece.
