Techniks 18851-3/16 Single Angle Collet Slimfit 6 3/16

Product Description

The TECHNIKS 18851-3/16 is a single angle collet in the SlimFIT 6 series, designed for precision tool holding in CNC machining and milling applications. With a 3/16-inch bore size, an overall length of 1.417 inches, and a body diameter of 0.394 inches, this collet delivers a total indicated runout (TIR) of 0.0001 inches. That level of concentricity is critical for high-speed cutting operations where tool deflection and runout directly affect surface finish and tool life. Machinists and tooling technicians rely on collets like this for consistent, repeatable clamping performance in production environments.

The 18851-3/16 fits SlimFIT 6 collet chucks and is suited for use in CNC machining centers where slim-profile toolholding is required. The slim body design allows access to tight workpiece features and close-clearance setups. This collet is appropriate for both roughing and finishing passes where accurate tool positioning is essential. It is installed by toolroom technicians and CNC operators working with 3/16-inch shank cutting tools such as end mills, drills, and reamers.

Key Features

• 3/16-inch bore size for direct clamping of 3/16-inch shank tooling
• TIR of 0.0001 inches for high-precision concentricity
• Overall length of 1.417 inches with a body diameter of 0.394 inches
• SlimFIT 6 series design enables access in tight or deep-cavity setups
• Single angle collet construction provides consistent clamping force distribution

Compatibility

Designed for use with SlimFIT 6 series collet chucks requiring a 3/16-inch bore single angle collet.

Installation Notes

Installation should be performed by a qualified toolroom technician or CNC operator. Always power down and lock out the machine spindle before seating or removing collets. Inspect the collet and chuck bore for chips or debris before assembly, as contamination directly degrades runout performance. Use the manufacturer-specified torque wrench and collet nut for proper clamping force - do not use improvised tooling to tighten the collet nut.
