WC is an 80° trigon (negative rake) insert family with strong cutting edges for steel, alloy steel, and cast iron at high material removal rate. Both are indexable U-drill standards. For 5D very-deep drilling on stainless \/ aluminum, SP is the better choice. For very-deep drilling on steel at high MRR, WC is typically preferred for rigidity.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eWhy choose 5D depth ratio over 2D\/3D\/4D\/6D+?\u003c\/summary\u003e\n\u003cp\u003e5D depth ratio is the deepest practical ratio for standard SP\/WC indexable U-drill bodies.

All BEYOND SP 5D indexable U-drill bodies in this collection (C20 \/ C25 \/ C32 \/ C40 shanks) have through-body internal coolant channels. At 5D depth, internal coolant is mandatory and very-high-pressure for stable chip evacuation. Coolant pressure requirements: 20-25 bar for small shanks, 25-30 bar for medium, 30-40 bar for heavy. Additionally, peck-cycle is mandatory (retract every 0.3-0.5× the drill diameter) to break chips before they pack in the deep flutes.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eCan I use Korloy or Mitsubishi SPGT \/ SPMT inserts in BEYOND SP 5D drill bodies?\u003c\/summary\u003e\n\u003cp\u003eYes. All BEYOND SP 5D drill bodies follow ISO 1832 standard for SPGT (positive trigon ground) and SPMT (positive trigon molded) inserts. Cross-brand equivalents from Korloy, Mitsubishi, Sumitomo, and Sandvik will fit the same pocket. The only check needed is IC size (5.0 \/ 6.0 \/ 7.0 \/ 9.0 \/ 11.0 \/ 14.0 mm) and matching insert thickness.

For 13-22mm drill, use C20 shank (9 SKUs). For 18-30mm drill, use C25 shank (25 SKUs). For 26-37mm drill, use C32 shank (27 SKUs). For 38-50mm drill, use C40 shank (13 SKUs).

Standard peck-cycle interval is 0.3-0.5× the drill diameter — for a 25mm drill, retract every 8-12mm. For stainless steel and other stringy-chip materials, use the shorter interval (0.3×).
