Tool-flo 93401616D Indexable Threading Toolholder 1x1

Product Description

The TOOL-FLO 93401616D is an external, right-hand indexable threading toolholder in the FLSR series, designed for turning centers and CNC lathes where precise thread-form cutting and grooving operations are required. The toolholder accepts FL 3R inserts and uses a clamp-style insert holding method for secure, repeatable positioning. With a 1 x 1 inch square shank and 6-inch overall length, it fits standard static and live tooling setups common in production and job-shop environments. Machinists and CNC setup technicians are the primary users of this toolholder.

This toolholder is suited for external threading and grooving applications on ferrous and non-ferrous materials. The FLSR series design places the cutting edge 1.25 inches back from the bar, supporting clearance in tight setups. It is rated for a maximum depth of cut of 0.21 inches and operates without through-coolant, making it straightforward to integrate into dry or flood-coolant setups where internal coolant delivery is not available or required.

Key Features

• External thread cutting and grooving capability in a single multi-use toolholder
• Right-hand cutting orientation for standard lathe rotation
• FL 3R insert compatibility with clamp-style holding for quick indexing
• 1 x 1 inch square shank fits common CNC turret and static toolpost bores
• 6-inch overall length with 1.25-inch back-of-bar to cutting edge dimension for clearance
• No through-coolant required, simplifying installation in standard turret positions

Compatibility

Designed for use with FL 3R series inserts. Compatible with external threading and grooving applications requiring a right-hand, clamp-style toolholder in the FLSR series with a 1 x 1 inch shank.

Installation Notes

Installation is performed by CNC machinists or toolroom technicians. Power down and lock out the machine before mounting or removing the toolholder from the turret. Torque the turret station fasteners per the machine tool manufacturer specifications, not those of the toolholder. Verify insert seating and clamp engagement before running the spindle, and confirm tool offset data is updated in the control after any toolholder change.
