Seco 00057651 Indexable Boring Bar 1/2 Inch Shank Right Hand

Product Description

The SECO 00057651 is an indexable boring bar designed for precision internal machining operations including boring and turning. Built from heavy metal for improved vibration damping, this toolholder accepts CD-style diamond inserts with a 5/32-inch inscribed circle and uses a screw clamping method for secure insert retention. It features a right-hand cut orientation, a negative rake angle of 0 degrees, and a -5 degree lead angle. The 1/2-inch shank diameter and 4-inch overall length make it suitable for tight-clearance bore work. Minimum bore diameter is 0.212 inches with a maximum bore depth of 1.12 inches. Installation and operation are handled by machinists and CNC tooling specialists in production and job-shop environments.

This boring bar is suited for both manual lathe and CNC turning center applications where small-diameter internal bores require a rigid, dampened toolholder. The SCLD toolholder style and diamond insert geometry support efficient material removal in steel and similar workpiece materials. With a center-to-cutting-edge dimension of 0.118 inches, the bar is optimized for controlled bore sizing in precision turning operations. It is a single-purpose, non-multi-use tool intended for dedicated boring and turning setups.

Key Features

• Heavy metal construction for superior vibration damping in small-bore applications
• Accepts CD.. 1.2 diamond inserts with 5/32-inch inscribed circle (insert size code 1.2)
• Screw insert clamping method for reliable, repeatable positioning
• Right-hand cut with negative rake and -5 degree lead angle for controlled cutting geometry
• Minimum bore diameter of 0.212 inches and maximum bore depth of 1.12 inches
• No coolant-through design; suitable for standard coolant-flood setups

Compatibility

Compatible with CD.. 1.2 diamond inserts featuring a 5/32-inch inscribed circle and 0.040-inch insert thickness. Insert screw CS115 is specified for this toolholder. Designed for use in SCLD-style toolholder setups on manual lathes and CNC turning centers.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and locked out before changing inserts or mounting the boring bar. The shank should be clamped securely in a compatible boring bar holder or turret station sized for a 1/2-inch shank. Follow the insert manufacturer's torque recommendations for the CS115 clamping screw, and verify bore diameter with a calibrated gauge before committing to a production run.
