Tool-flo 96001656 Indexable Threading Toolholder 1x1

Product Description

The TOOL-FLO 96001656 is an external, right-hand indexable threading toolholder designed for precision thread-cutting and grooving operations on CNC lathes and turning centers. Built around the On-Edge series platform, it accepts T.MA/C 43 inserts held in place by a clamp-and-pin mechanism for secure, repeatable positioning. The 1 x 1 inch square shank accommodates standard toolpost and turret setups, while the 6-inch overall length provides adequate reach for most external threading applications. Weighing 5 pounds, this is a solid, production-grade holder suited for machinists and toolroom technicians working in job shop or high-volume manufacturing environments.

This toolholder is used for external threading and grooving on turned parts in both job shop and production settings. The right-hand cutting orientation is standard for conventional lathe setups where the tool feeds toward the chuck. The On-Edge insert seating style positions the insert cutting edge at a geometry optimized for thread form accuracy. It does not include a coolant-through or coolant entry feature, making it straightforward to set up in dry or flood-coolant applications where coolant is applied externally. Machinists running general-purpose threading cycles will find the clamp-and-pin retention system reliable for maintaining insert index position across multiple parts.

Key Features

• External threading and grooving capability in a single toolholder
• Right-hand cutting orientation for standard lathe configurations
• Clamp-and-pin insert holding method for secure, repeatable indexing
• Accepts T.MA/C 43 inserts with 0.5 inch inscribed circle
• On-Edge series insert seating for optimized thread form geometry
• No coolant-through design simplifies setup in flood or dry cutting conditions

Compatibility

Compatible with T.MA/C 43 indexable inserts with a 0.5 inch inscribed circle. Designed for use in standard 1 x 1 inch square shank toolpost and turret positions on CNC or manual lathes and turning centers configured for external threading operations.

Installation Notes

Installation is typically performed by a machinist or toolroom technician familiar with lathe toolpost or turret setup procedures. Ensure the machine is powered down and the spindle is fully stopped before mounting or adjusting the toolholder. Verify insert seating and clamp engagement before taking any cut. Follow the machine manufacturer's torque specifications for toolpost fasteners and confirm correct tool centerline height before beginning threading cycles.
