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.

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.

Use with a tap to thread holes by hand. These wrenches are more compact than straight-handle tap wrenches, so they can be used to tap in tighter spaces. However, they provide less leverage.

Wrenches with aligner square your tap to your work surface for proper alignment and reduced tap breakage. A V-groove at the base provides stability on round surfaces.

Sliding handle moves from side to side to allow tapping in spaces where fixed handles don't have room to turn.

Sliding ratcheting handle moves from side to side and can lock in a fixed position. It adjusts for right- or left-hand ratcheting.

Machine-mount wrenches have a guide shank that fits into the chuck on your drill press and holds the tap steady. Use them after drilling to thread holes manually without moving the workpiece.

Pair with Dremel rotary tools to securely grip bits and burs.

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.
