Techniks 18851-05.5 Single Angle Collet Slimfit 6 5.5mm

Product Description

The TECHNIKS 18851-05.5 is a single angle collet in the SlimFIT 6 series, designed for precision tool holding in CNC machining centers and milling applications. With a collet size of 5.5 mm, an overall diameter of 0.394 inches, and an overall length of 1.417 inches, this collet delivers a total indicator runout (TIR) of 0.0001 inches for high-accuracy concentricity. It is intended for use by machinists and toolroom professionals who require tight tolerances and reliable clamping force during high-speed or precision cutting operations.

The SlimFIT 6 collet is suited for use in slim-nose collet chucks common in production machining environments where clearance to the workpiece or fixture is limited. The compact body diameter of 0.394 inches allows access in tight areas without sacrificing gripping performance. This collet is appropriate for both roughing and finishing passes where runout control directly affects surface finish and tool life.

Key Features

• Collet size: 5.5 mm for precise bore matching to tool shank diameter
• TIR of 0.0001 inches for high-concentricity tool holding
• Overall length of 1.417 inches for consistent reach and clamping depth
• Maximum body diameter of 0.394 inches suits slim-profile chuck systems
• Single angle design provides uniform clamping pressure around the tool shank

Compatibility

Designed for use with SlimFIT 6 series collet chucks that accept single angle collets with a 0.394-inch body diameter and 5.5 mm bore size.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's torque and assembly procedures for collet chucks. Always power down and lock out the spindle before seating or removing collets. Inspect the collet bore and chuck taper for chips or debris before installation, as contamination directly affects runout performance. Do not exceed the collet's rated clamping range by using an undersized or oversized tool shank.
