Carmex 100-3IN.RHHOL Threading Toolholder 1 in Shank

Product Description

The CARMEX 100-3IN.RHHOL is an indexable threading toolholder designed for internal threading operations. Built to the SIR series style, this right-hand holder accepts 16IR inserts secured by a screw-clamping mechanism. The 1-inch shank diameter and 8-inch overall length make it a practical fit for CNC lathes and manual turning centers running internal thread cycles. Minimum bore diameter is 1.16 inches, and the insert inscribed circle measures 3/8 inches. The toolholder does not include a coolant-through port, so coolant delivery must be handled externally or by flood coolant setup at the machine.

This toolholder is intended for threading operations on internal bores in ferrous and non-ferrous workpieces across production and job-shop environments. Machinists and CNC operators running thread-turning cycles on turning centers or manual lathes will find this holder suited to standard internal threading work where bore access permits the 1.16-inch minimum bore entry. The SIR 1000 R16 style designation aids in matching to compatible inserts and existing tooling programs.

Key Features

• Right-hand, internal threading configuration for bore thread applications
• Accepts 16IR indexable threading inserts, secured by screw clamp
• 1-inch shank diameter with 8-inch overall length for rigid reach
• Minimum bore diameter of 1.16 inches allows threading in compact bores

• No coolant-through design keeps setup simple where flood coolant is standard

Compatibility

Designed for use with 16IR series indexable threading inserts. Style designation SIR 1000 R16 should be referenced when selecting compatible inserts and tooling accessories. Verify bore diameter clearance against the 1.16-inch minimum bore requirement before installation.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before mounting or adjusting the toolholder. Confirm shank seating and clamping torque against the machine turret or toolpost manufacturer specifications. Verify insert orientation and thread direction match the programmed cycle before making a cut.
