Kennametal 1291354 Tapping Adapter RC1 Series

Product Description

The KENNAMETAL 1291354 is a quick-change tapping adapter designed for precision tapping operations in CNC machining centers and tapping machines. Sized for a No. 1 tap, it accepts a tap shank diameter of 0.194 inches and a tap square size of 0.152 inches. The adapter features through-coolant capability, delivering cutting fluid directly to the tap for improved chip evacuation and tool life. Belonging to the RC1 series, it offers a standardized interface for quick tool changes without sacrificing rigidity or concentricity. This adapter is installed by machinists and tooling technicians in production and job-shop environments.

The 1291354 is suited for use in rigid tapping applications on vertical and horizontal machining centers as well as dedicated tapping machines. Its compact overall length of 1.100 inches and flange diameter of 1.180 inches make it appropriate for confined workpiece clearances. The through-coolant design makes it particularly well suited for tapping deeper holes where flood coolant alone is insufficient. The RC1 series interface is common in production environments requiring repeatable tool changes across multiple spindles.

Key Features

• Quick-change interface for fast tool swaps in production environments
• Through-coolant capability improves chip flushing and tap longevity
• Tap shank diameter of 0.194 inches and tap square size of 0.152 inches for No. 1 tap sizing
• Compact projection of 0.280 inches minimizes overhang and improves rigidity
• RC1 series standardized interface for consistent fitment across compatible holders
• Outside shank diameter of 0.750 inches for secure holder engagement

Compatibility

Designed as an OEM-style replacement adapter for RC1 series quick-change tapping systems accepting a No. 1 tap adapter size with a 0.750-inch outside shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the control is in an e-stop or tool-change state before installing or removing the adapter. Verify the through-coolant port is clear and properly aligned with the spindle coolant supply before initiating a tapping cycle. Consult the machine tool builder documentation for torque requirements on locking mechanisms specific to the spindle interface.
