Techniks 83512-1/4 Single Angle Collet SYOZ20/EOC12 1/4 Inch

Product Description

The TECHNIKS 83512-1/4 is a single angle collet designed for use with SYOZ20/EOC12 collet systems. It accepts a 1/4 inch tool shank and features a maximum body diameter of 0.78 inches and an overall length of 1.34 inches. The collet holds a total indicated runout (TIR) of 0.0004 inches, making it suitable for precision machining applications where concentricity is critical. Machinists and toolroom technicians install this collet into compatible toolholding chucks on CNC machining centers and manual milling equipment to secure cutting tools with consistent grip and minimal deviation.

This collet is intended for use in shops running SYOZ20 or EOC12 compatible toolholding systems. It is well suited for light to medium milling, drilling, and reaming operations where a 1/4 inch shank tool is required. The compact overall length and tight TIR spec make it a practical choice for production environments and precision setups where tool runout directly affects part quality.

Key Features

• 1/4 inch shank capacity for common end mills, drills, and reamers
• 0.0004 inch TIR for high-precision, low-runout toolholding
• 0.78 inch maximum body diameter fits SYOZ20/EOC12 chuck bores
• 1.34 inch overall length for compact toolholder assemblies
• Single angle collet design for secure, uniform clamping force

Compatibility

Designed for use with SYOZ20/EOC12 series collet chucks and compatible toolholding systems accepting 1/4 inch shank tooling.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before changing collets. Inspect the collet bore and chuck taper for chips or debris before seating the collet, as contamination will increase runout beyond the rated TIR. Torque the collet nut per the toolholder manufacturer specifications using the appropriate spanner wrench.
