Techniks 18851-04 Slimfit 6 Single Angle Collet 4mm

Product Description

The TECHNIKS 18851-04 is a single angle collet in the SlimFIT 6 series, designed for precision tool holding in CNC machining centers and milling applications. It accepts a 4.00 mm collet size and features a maximum body diameter of 0.394 inches and an overall length of 1.417 inches. The total indicator runout (TIR) is rated at 0.0001 inches, making it suitable for high-precision work where concentricity is critical. Machinists and toolroom technicians install this collet into compatible SlimFIT 6 toolholders as part of a complete tool assembly.

This collet is intended for use in precision machining environments, including production shops and toolrooms running CNC vertical or horizontal machining centers. The SlimFIT 6 series is engineered for applications where slim-profile toolholding is required, such as deep-cavity milling or die and mold work where clearance is limited. The 4.00 mm collet size accommodates appropriately sized round shank cutting tools.

Key Features

• 0.0001 inch TIR for high-precision concentricity in demanding machining operations
• 4.00 mm collet size for standard round shank tooling
• 0.394 inch maximum body diameter suits slim-profile toolholding requirements
• 1.417 inch overall length for compact tool assembly
• Single angle design for secure, repeatable clamping in compatible holders

Compatibility

Designed for use with TECHNIKS SlimFIT 6 series toolholders that accept single angle collets in the 4.00 mm collet size range.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with precision collet toolholding systems. Ensure the spindle and toolholder are fully de-energized and the machine is in a safe, locked-out state before handling or changing collets. Clean all mating surfaces before assembly to maintain the rated TIR specification. Follow the toolholder manufacturer's torque guidelines and never use damaged or contaminated collets.
