Seco 00093178 Indexable Boring Bar 5/8 in Left Hand Carbide

Product Description

The SECO 00093178 is a solid carbide indexable boring bar designed for precision internal boring and turning operations on CNC lathes and machining centers. Built to the E-SCLC toolholder style, it accepts CC.. 21.5.. series diamond-shaped inserts secured by a screw clamping method. The bar features a 5/8 inch minimum bore diameter, an 8 mm shank diameter, a 95-degree lead angle, and a neutral rake angle of 0 degrees. At 8 inches overall length, it provides solid reach for deeper bore applications. Coolant-through capability supports chip evacuation and tool life in demanding cuts.

This boring bar is suited for left-hand cutting operations in both boring and turning applications. It is commonly used by machinists and toolroom professionals working on CNC lathes, turret lathes, and live-tooling setups where a left-hand orientation is required. The solid carbide construction makes it appropriate for high-speed, precision applications where rigidity and dimensional stability are critical. Compatible insert size code is 21.5, with an insert inscribed circle of 0.25 inches and an insert thickness of 0.094 inches.

• Screw-clamp insert retention with CC.. 21.5.. diamond insert compatibility
• Coolant-through design aids chip evacuation and reduces thermal buildup
• Neutral rake angle suitable for a wide range of workpiece materials

Compatibility

Accepts CC.. 21.5.. series diamond-shaped indexable inserts with a 1/4 inch inscribed circle and 3/32 inch thickness. Compatible insert size code is 21.5.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the shank in a toolholder or turret with appropriate clamping torque per the machine tool manufacturer specifications. Power down and lock out the machine before changing inserts or repositioning the bar. Verify correct left-hand orientation and lead angle clearance before initiating a cut.
