T-slot and undercut cutters for slots, grooves and keyways.

Cutters for Controlled T-Slot Machining
Purpose-built cutters for machining T-slots in tables, fixtures, and components — configured around slot width, depth, neck clearance, material, and machine conditions.
T-slot cutter selection begins with the finished slot geometry and the condition of the prepared access slot.
The cutting diameter and edge geometry are defined around the required T-slot width and fit.
Neck diameter, length, and shank configuration are evaluated against the entry slot and component geometry.
Cutting material and coating can be matched to the workpiece, machine stability, and production volume.
Non-standard widths, depths, radii, chamfers, and shank configurations can be produced from an approved drawing.
Provide the slot width, undercut diameter or width, depth, entry-slot size, corner or radius requirements, workpiece material, machine and holder, coolant method, and expected volume. These details determine cutter geometry, neck clearance, cutting material, and the recommended machining approach.
