Tool-flo 93401608C Threading Toolholder 1x1 Inch Shank

Product Description

The TOOL-FLO 93401608C is an indexable threading toolholder engineered for external threading and grooving operations on lathes and turning centers. Built in the FLSR series with a right-hand cutting orientation, this toolholder accepts FL 2R inserts held securely by a clamp-style insert holding method. The shank measures 1 inch wide by 1 inch tall with a 5-inch shank length and 5-inch overall length, fitting standard tool turrets and block holders common in production and job-shop environments. Machinists and CNC lathe operators rely on this style of holder for consistent thread geometry and repeatable insert indexing on external workpiece diameters.

The 93401608C suits external threading and grooving applications in both production turning and general machining environments. Its right-hand designation means cutting proceeds toward the spindle in the standard orientation. The toolholder supports a maximum depth of cut of 0.14 inches and has a back-of-bar to cutting edge measurement of 1.25 inches, allowing clearance planning for tight-tolerance threading passes. It is configured without coolant-through capability, making it appropriate for dry or flood-coolant setups where coolant is directed externally. The multi-use designation confirms suitability for both threading and grooving work with compatible FL 2R inserts.

Key Features

• FLSR series right-hand external threading and grooving toolholder
• Accepts FL 2R indexable inserts with clamp-style insert retention
• 1 inch by 1 inch square shank with 5-inch overall length for standard turret compatibility
• Maximum depth of cut: 0.14 inches
• Back of bar to cutting edge: 1.25 inches for consistent reach and clearance planning
• No coolant-through configuration - compatible with external flood or dry cutting setups

Compatibility

Designed for use with FL 2R series indexable inserts. Fits standard 1-inch square shank tool stations on CNC lathes and turning centers. Verify turret pocket dimensions and insert grade selection against workpiece material before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator with the machine powered off, the spindle locked, and all stored energy discharged before handling the turret. Secure the shank in the tool station per the machine manufacturer's torque and clamping specifications - do not rely on hand-tightening alone for production cuts. Confirm insert seating and clamp engagement before taking a test pass. Follow your facility's tooling change procedures and applicable machine safety standards.
