Q50.0 (Shank Diameter): The straight cylindrical shank of the drill body has a diameter of 50.0 mm. This large shank slides directly into your 50mm CNC lathe turret pocket or matches the CNC Turret Sleeve Q50 series we discussed earlier.
WL-8XOAL-150 (Tool Code & Reach): This represents the manufacturer's series coding (often corresponding to specialized high-clearance drilling bodies). The 150 indicates a deep functional drilling reach or absolute flute length of 150 mm, enabling deep-hole processing.
INS-SPMG 060204 (Insert Compatibility): The pocket seat is machined specifically to accept standard SPMG 060204 indexable square carbide inserts. These inserts feature 4 cutting edges, making them highly economical for rapid chip removal.
(M2.2) (Locking Screw Thread): The pocket uses a small M2.2 thread screw (typically an M2.2 x 5mm Torx screw) to tightly lock down the SPMG insert into the seat pocket.
