Value Collection FLEX3/4 Indexable Countersink 3/4 in Shank

Product Description

The VALUE COLLECTION FLEX3/4 is an indexable countersink designed for precision chamfering and countersinking operations in metal fabrication and machining environments. The tool accepts triangle TCMT 16T304 inserts, allowing the cutting edge to be indexed or replaced without removing the entire tool body from the setup. With a maximum cutting diameter of 1 inch and a 3/4 inch shank diameter, this countersink is built for use in machine tools where rigidity and repeatability are priorities. The adjustable included angle feature gives machinists flexibility across different countersink angle requirements without switching to a different tool body.

This countersink is suited for use in CNC machining centers, manual mills, and drill presses where countersinking or chamfering of drilled holes is required. It is commonly used in metal fabrication shops, aerospace component machining, and general manufacturing environments. The 3/4 inch shank fits standard ER and straight-shank toolholders commonly found in production machine setups. Licensed machinists and tool and die professionals are the primary installers and operators of this tooling.

Key Features

• Indexable design uses triangle TCMT 16T304 inserts for fast edge replacement without full tool removal
• Adjustable included angle accommodates multiple countersink angle requirements in a single tool body
• 1 inch maximum cutting diameter for chamfering larger bored or drilled holes
• 3/4 inch shank diameter fits standard straight-shank and ER toolholders
• Eliminates regrinding downtime associated with solid HSS or brazed carbide countersinks

Compatibility

Designed as an OEM-style indexable countersink body compatible with triangle TCMT 16T304 inserts. Fits machine tool spindles and toolholders accepting a 3/4 inch straight shank.

Installation Notes

Installation and operation should be performed by a qualified machinist familiar with cutting tool setup and machine tool operation. Always power down and lock out the machine spindle before indexing or replacing inserts. Secure the shank firmly in the toolholder to the manufacturer-specified clamping torque for the holder type in use, and verify runout before beginning production cuts. Follow applicable shop safety standards and machine tool manufacturer guidelines during setup.
