Seco 00093165 Indexable Boring Bar 0.5in Min Bore Sclc

Product Description

The SECO 00093165 is a right-hand SCLC indexable boring bar designed for internal turning operations on CNC lathes and manual turning centers. Built from solid carbide, the bar features a 3/8 inch shank diameter and a 6 inch overall length, with a minimum bore diameter of 0.5 inches. Through-coolant capability delivers cutting fluid directly to the insert tip, extending tool life and improving chip evacuation in deep-bore applications. The screw-clamp holding method secures CC.. 21.51 diamond-shaped inserts at a neutral rake angle and a -5 degree lead angle, providing stable, predictable cutting geometry. Licensed machinists and CNC operators are the primary installers of this toolholder.

This boring bar is suited for precision internal diameter turning in production and job-shop environments. The SCLC toolholder style accepts CC.. 21.51 inserts with a 1/4 inch inscribed circle, making it appropriate for finishing and semi-finishing passes in bores starting at 0.5 inches. The through-coolant feature makes this bar particularly well-suited for stainless steel, high-temperature alloys, and other materials where heat management at the cutting edge is critical. It is configured for right-hand cutting direction only.

Key Features

• SCLC toolholder style with screw-clamp insert retention for repeatable indexing
• Compatible with CC.. 21.51 diamond-shaped inserts, 1/4 inch inscribed circle
• Neutral rake angle with -5 degree lead angle for controlled chip formation
• Right-hand cutting direction; 0.25 inches center-to-cutting-edge dimension

Compatibility

Accepts CC.. 21.51 SCLC-style diamond inserts with a compatible insert size code of 21.5 and a 1/4 inch inscribed circle. Also referenced under MSC/Manufacturer Number E06-SCLCR-2.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC tooling technician. Confirm the machine spindle is fully stopped and the turret is locked out before changing or indexing inserts. Ensure the shank bore and coolant port are clear of chips before seating the bar. Follow the toolholder manufacturer torque guidance for the clamping screw to avoid insert movement during cutting.
