Micro 100 40-2500 Indexable Boring Bar Set Through Coolant

Product Description

The MICRO 100 40-2500 is a right-hand indexable boring bar set designed for precision internal turning and boring operations on CNC lathes and manual turning centers. The set spans a minimum bore range from 0.63 inches on the smallest bar to 0.925 inches on the largest bar, covering a practical range of small-diameter bore work. All bars in the set are designed with through-coolant capability, which directs cutting fluid directly to the insert tip for improved chip evacuation and extended insert life. The set uses CCMT 21.51 inserts and is suited for machinists and toolroom professionals working with tight-tolerance bores.

This set is applicable to production turning environments, job shops, and toolroom operations where multiple small-bore diameters must be machined with consistent tooling. The through-coolant design makes it well suited for deep-bore applications where chip packing and heat buildup are common concerns. The toolholder styles included are A08K SCLCR 3, A10M SCLCR 3, and A12Q SCLCR 3, covering the bore range in graduated steps. Installation is performed by machinists and CNC setup technicians.

Installation Notes

These boring bars are installed and set up by machinists or CNC lathe technicians. Ensure the machine spindle is fully stopped and the coolant system is depressurized before changing tooling. Bar overhang should be minimized to the extent the bore depth allows in order to reduce chatter and deflection. Verify insert seating and screw torque per the insert manufacturer's toolholder documentation before cutting.
