BAP (184 SKUs, the largest series) is the general-purpose right-angle face/shoulder mill with APMT 1135 / 1604 inserts. EAP (29 SKUs) is a similar but stiffer design for heavier-duty 90° shoulder milling with higher feed rates. Use BAP for most general jobs; switch to EAP when you need higher rigidity for cast iron or interrupted cuts.

Yes — the BEYOND R390 series is dimensionally compatible with Sandvik R390-11T3 and R390-18 inserts. The shank geometry, pocket dimensions, and clamp angles match Sandvik's specs, so you can run genuine Sandvik R390 inserts in a BEYOND shank (and vice versa) with no fitting issues. This makes the BEYOND shank a cost-effective alternative for Sandvik-tooled shops.

The "C" prefix means cylindrical shank (round), and the number is the shank diameter in millimeters. C16 = 16mm round shank, C20 = 20mm, C25 = 25mm, C32 = 32mm. Cylindrical shanks fit standard milling chucks, hydraulic holders (like HSK63 / HSK100 shrink-fit), and direct collet adapters. This is the most common shank format in CNC milling worldwide.

Each shank series is designed for specific insert codes (see the "Compatible Inserts by Series" table above). The insert code is usually stamped on the shank body near the pocket, and the same code is in the product SKU. For example, BAP300R-C25-26-150-2T uses APMT 1135 inserts with a 11.5mm IC and 3.5mm thickness. The corresponding insert is APMT 1135-PM (or similar grade like APMT 1135-HF for high-feed).

Standard shanks have a cutting depth of 1-3mm for square shoulder / face milling. For deeper cuts (5-10mm), use the BAP 300R series with longer shank reach (the 200mm / 250mm / 300mm reach variants). For very deep slots, use the T-series or TJU slotting cutters which are designed for deeper cuts. The shank reach (R or "L" in the SKU) determines the maximum depth the cutter can reach into the workpiece.

Yes. BEYOND offers custom shank manufacturing for orders of 10+ pieces. Common custom requests include non-standard shank diameters (e.g., C18 or C22), longer reach, special coatings (TiN, AlTiN, DLC), and custom insert pockets.
