Seco 00071928 Srdc Indexable Turning Toolholder 1x1 Rcmt

Product Description

The SECO 00071928 is a neutral-hand SRDC-style indexable turning toolholder designed for general-purpose lathe and turning center applications. It features a 1 inch by 1 inch square shank and an overall length of 7 inches. The toolholder uses a screw-lock insert holding method to secure RCMT-style inserts, providing rigid clamping and repeatable insert positioning during cuts. The head length measures 1.26 inches with a back-of-bar to cutting edge distance of 0.736 inches. Built from steel, this holder is suited for neutral cutting direction operations across a broad range of workpiece materials. Licensed machinists and CNC turning specialists are the primary installers.

This toolholder is intended for turning operations on CNC lathes and manual turning centers where a neutral-hand, zero-rake configuration is required. Its universal material compatibility rating makes it appropriate for use on ferrous metals, non-ferrous alloys, stainless steels, superalloys, and cast materials. The screw-lock series design is a common standard in production turning environments where quick insert changes and consistent tool offset retention are priorities.

Key Features

• SRDC toolholder style with neutral hand and neutral rake angle (0 degrees)
• Screw-lock insert holding method for secure, repeatable clamping
• Accepts RCMT inserts with a 0.472 inch inscribed circle (compatible insert size: RCMT 1204)

• No coolant-through feature; suitable for external coolant delivery setups

Compatibility

Designed to accept RCMT inserts, specifically compatible insert size code RCMM43 and complete insert compatibility RCMT 1204. Suitable for use in standard turning and lathe applications across universal workpiece material categories.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the tool turret is in a safe index position before mounting or removing the toolholder. Use the appropriate torque wrench and screw drive for the insert clamping screw to avoid stripping the screw lock mechanism. Verify tool offset and insert seating after installation before resuming cutting operations.
