Installation Notes

Installation is performed by machinists or toolroom technicians. The machine spindle must be fully stopped and the tool secured in a vise or holder before inserting or removing the spade drill insert. Use the correct torx or hex key as specified by the holder manufacturer to seat the insert firmly without over-torquing the clamping screw. Inspect the seat and insert pocket for chips or debris before each insert change to ensure proper seating and accurate hole geometry.
