BEYOND SP C32-5D-SD32-SP09
32mm 5D Indexable U-Drill | Professional CNC Deep Hole Boring Body
High-Efficiency 32mm Deep Hole Specialist
The BEYOND SP C32-5D-SD32-SP09 is a high-performance indexable insert drill engineered for precision metal removal. With a 32mm cutting diameter and a powerful 5D depth ratio, this fast hole U-drill is the ultimate tool for deep hole boring in tough alloys and structural steels. Designed for CNC lathe metal boring, its optimized internal cooling system ensures superior chip evacuation and thermal stability during high-speed drilling.

20CrMnTi Alloy & Advanced Spiral Flute
Superior Tool Body Material: Manufactured from premium 20CrMnTi alloy steel, this U-drill body undergoes vacuum quenching to ensure HRC 50-55 surface hardness. This prevents deformation during large diameter boring while providing the core toughness needed for intermittent cuts.
Efficient Chip Evacuation: The spiral flute (U-groove) is designed with an enlarged space for smooth chip flow. Combined with dual internal coolant channels, it effectively flushes metal chips out of the 160mm deep hole, reducing friction and extending the life of your carbide inserts.
Recommended Cutting Parameters (5D 32mm)
Baseline values for Carbon Steel (HB < 250). Always use internal coolant:
- Cutting Speed (Vc): 110 - 160 m/min
- Feed Rate (f): 0.08 - 0.15 mm/rev
- Rotation Speed (N): Calculated as $$N = \frac{Vc \times 1000}{\pi \times 32}$$
- Coolant Pressure: Minimum 1.5 MPa for 5D depth to avoid chip packing.
SP Series U-Drill: Advantages & Considerations
- Uses 4-edge SPMG square inserts (Highly cost-effective).
- Superior hole straightness and verticality in 5D depths.
- Greater body rigidity compared to WC trigon types.
- Requires higher spindle torque.
- Strict reliance on stable internal coolant flow.
Verified Customer Feedback

- Robert H. (USA)"Perfect chip flow"
"The spiral flute is deep enough that chips never jam. Excellent internal cooling system."
- Klaus M. (Germany)"Great for CNC lathes"
"Rigidity is key for 5D drilling, and this tool delivers exactly as promised."
- Kenji Y. (Japan)"Smooth finish"
- Marc L. (France)
"Best value 5D drill"
- Liam G. (UK)
Technical Q&A
Q: Can I use this for shallow hole drilling as well?
A: Absolutely. While optimized for 5D, it is perfectly capable of shallow boring, offering maximum versatility for your shop.
Q: Does this include the SPMG09 inserts?
A: No, this is the tool body only. We recommend pairing it with BEYOND SPMG090408 inserts for best results.
Q: Is a pilot hole necessary for 32mm 5D?
A: For 5D depths, we recommend starting with a 1D or 2D U-drill to ensure the 5D follows a perfectly straight path.
Technical Tip: WC vs. SP U-Drills
SP Series (Square): The professional choice for Blind Hole (Blind Bores) because the square insert geometry creates a flatter hole bottom. It is the gold standard for Deep Hole (5D) drilling due to superior core rigidity.
WC Series (Trigon): Primarily used for Through Hole applications. WC inserts offer more cutting edges but the tool core is thinner, making it slightly less rigid than SP for extreme depths.

Technical FAQ & Buying Guide
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
