Tool-flo 93402020D Indexable Threading Toolholder 1.25 in

Product Description

The TOOL-FLO 93402020D is an external, right-hand indexable threading toolholder in the FLSR series, designed for precision threading and grooving operations on CNC lathes and turning centers. The square shank measures 1.25 inches wide by 1.25 inches tall with a 6-inch overall length, providing a rigid, stable platform for interrupted and continuous thread-cutting passes. It accepts FL 4R inserts held by a clamp-style insert holding method, and operates without through-coolant or special coolant entry. Machinists and tool-crib technicians in production shops and job shops are the primary users of this toolholder.

The 93402020D suits external threading and grooving applications on workpieces where a right-hand, straight-shank toolholder is required. The FLSR series configuration positions the back of bar to cutting edge at 1.5 inches, supporting a maximum depth of cut of 0.29 inches. It is rated as a multi-use tool, making it applicable across both threading and grooving setups without changing the holder body. Typical installations involve gang tooling blocks, quick-change turrets, or standard OD turning tool stations on manual or CNC lathes.

Key Features

• External, right-hand thread orientation for standard OD threading operations
• FLSR series toolholder style with FLS geometry for consistent insert seating
• Accepts FL 4R indexable inserts with clamp-style holding for secure, repeatable edge positioning
• 1.25 x 1.25 inch square shank provides high rigidity and minimizes deflection under cutting loads
• Maximum depth of cut of 0.29 inches supports both threading and grooving in a single holder
• Multi-use designation allows grooving and threading operations without swapping holder bodies

Compatibility

Designed for use with FL 4R indexable inserts. Compatible with lathe and turning center tool stations that accept a 1.25 x 1.25 inch square shank toolholder in a right-hand external configuration.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before seating or removing the toolholder from the turret or tool block. Ensure the shank bore or pocket is clean and free of chips before clamping. Torque all hold-down fasteners to the machine manufacturer's specification - do not exceed published values for the turret or quick-change block in use.
