Indexable T-Slot Milling Cutter Series | BEYOND
BEYOND T-slot mills for DIN 650 / ISO 299 machine tool tables. 7 series covering cylindrical shank, arbor mount, and K40 bore. Indexable inserts for all standard slot widths.
The BEYOND T-slot milling cutter series is a comprehensive catalog of indexable T-slot cutters for machining T-slots in machine tool tables, fixture bases, and clamping surfaces. Each cutter follows the DIN 650 / ISO 299 standard for T-slot dimensions, ensuring compatibility with all standard machine tool tables worldwide. The cutters accept replaceable carbide inserts following the ISO 1832 geometry standard, so a single arbor can run multiple slot widths by changing inserts.
This collection is part of the broader BEYOND tool holder family and works with any ISO 1832 standard insert. For cylindrical shank mill bodies used in T-slot adjacent operations, see the Milling Shank Series. For face milling, see the Face Mill Hub.

Frequently Asked Questions
1. What is the standard T-slot size for CNC machine tool tables?
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.
2. What's the difference between TMR and HTS T-slot cutters?
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.
3. Can I use the same insert for different T-slot sizes?
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.
4. What's the maximum depth of cut for T-slot cutters?
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.
5. What's the difference between SMC and SMD T-slot cutters?
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+).
6. Can I get a custom T-slot size (e.g., T24 or T32)?
Yes. BEYOND offers custom T-slot cutter manufacturing for non-standard sizes, with a 5-piece MOQ and 2-3 week lead time. Common custom requests include T24, T26, T30, T32, T40, and special metric/imperial slot widths. Contact sales at chao@cnchome-beyond.com or WhatsApp +86 15990663752 for a custom quote.
