Tool-flo 96501616 Internal Threading Toolholder 1x1 in

Product Description

The TOOL-FLO 96501616 is an indexable internal threading toolholder designed for precision thread cutting and grooving in bore applications. Built on the Flo-Lock series platform, this right-hand holder accepts FL 3L inserts secured by a clamp-style insert holding method. The shank measures 1 x 1 inch with an overall length of 12 inches, giving machinists adequate reach for deep-bore work. A minimum bore diameter of 1.375 inches defines the smallest bore this toolholder can service. Coolant-through capability supports chip evacuation and thermal control during continuous threading cycles. This tool is handled and installed by CNC machinists and tool-room technicians in production or job-shop environments.

The 96501616 is suited for internal threading and grooving operations on lathes and turning centers where a right-hand, straight-shank toolholder is required. The Flo-Lock series is engineered for rigid insert clamping, making it appropriate for both light finishing passes and heavier threading cycles in ferrous and non-ferrous materials. The multi-use designation means this holder handles both threading and grooving insert geometries within compatible FL 3L insert families, reducing the number of dedicated holders needed at a turret station.

Key Features

• Internal thread cutting and grooving capability in a single toolholder
• Right-hand orientation with a 1 x 1 inch square shank
• Flo-Lock series clamp-style insert retention for rigid, repeatable insert seating
• Coolant-through design for improved chip flow and tool-tip cooling
• 12 inch overall length provides extended reach into deep bores
• Center to cutting edge dimension of 0.688 inches supports precise bore centerline alignment

Compatibility

Designed for use with FL 3L series inserts. Compatible with CNC lathes and turning centers that accept a 1 x 1 inch square-shank internal toolholder. Toolholder style is A16.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine in a full stop, spindle-off condition and all energy sources locked out per shop LOTO procedures. Confirm insert seating and clamp torque against the toolholder manufacturer specifications before initiating a cut. Verify bore clearance against the 1.375 inch minimum bore diameter before mounting. Coolant-through lines should be connected and flow confirmed prior to running threading cycles to prevent premature insert wear.
