The most common T-slot size for CNC machine tool tables is T14 or T16 (14mm or 16mm slot width). Smaller benchtop machines use T10 or T12, while large floor-standing machines use T18, T20, or T22. Extra-large machines (over 50HP spindle) may use T28 or T36. Check your machine's manual for the exact T-slot size before ordering a cutter.

TMR series uses round RPMT inserts for a combined T-slot + face mill operation in one pass. HTS uses rhombic CCMT inserts for T-slot only. Use TMR when you need to machine both the T-slot walls and the top surface in a single operation (saves cycle time). Use HTS for dedicated T-slot cutting where face milling is done separately.

Yes — the insert size is independent of the T-slot width. For example, CCMT 060204 fits the same pocket on T12, T14, T16, and T18 cutters (the body is sized for the slot width, but the insert pocket is the same). The cutter body's outer diameter and tooth count change with the T-slot size, but the insert specification stays the same within a series. This simplifies insert inventory.

Standard T-slot cutters machine the full T-slot depth in one pass. The depth is determined by the T-slot size (T14 = 11mm depth, T16 = 13mm, T18 = 15mm, T20 = 17mm, T22 = 19mm, T28 = 24mm, T36 = 30mm). For deeper T-slots (custom), special order is available. The body length (e.g., 120mm, 150mm, 200mm) determines the reach into the workpiece.

Both are disc-style T-slot cutters with K40 bore, used on face mill arbors. SMC is a single-row design with MPHT 060304 inserts for medium-duty T-slots. SMD is a denser design with MPHT 080305 inserts for high-feed heavy T-slots. Use SMC for standard machine tables (T14-T18). Use SMD for high-feed roughing or larger T-slots (T20+).
