BEYOND SP C32-5D-SD33-SP09
Professional 33mm 5D Indexable U-Drill | High-Stability CNC Deep Hole Boring Body
Industrial-Grade 33mm Deep Hole Specialist
The BEYOND SP C32-5D-SD33-SP09 is a high-performance indexable insert drill designed for heavy-duty material removal. Featuring a 33mm cutting diameter and a powerful 5D depth ratio, this fast hole U-drill is engineered for deep hole boring in tough alloys and structural steels. Its internal cooling system ensures superior chip evacuation and thermal control during continuous high-speed drilling on CNC lathes and machining centers.

20CrMnTi Alloy & High-Efficiency Spiral Flute
Superior Tool Body Material: This U-drill body is forged from premium 20CrMnTi alloy steel. The body achieves a surface hardness of HRC 50-55 through vacuum quenching, ensuring high durability while maintaining the core toughness required for shallow hole drilling and deep 165mm penetration without breakage.
Optimized U-Groove Spiral Flute: The spiral flute geometry is precision-engineered to provide maximum chip space. Paired with dual internal coolant channels, it effectively flushes chips out of the hole bottom, ensuring a smooth surface finish and preventing chip welding on the carbide inserts.
Recommended Cutting Parameters (33mm 5D)
Baseline settings for Carbon Steel (HB < 250). Adjust based on material hardness:
- Cutting Speed (Vc): 110 - 160 m/min
- Feed Rate (f): 0.06 - 0.12 mm/rev
- Rotation Speed (N): $$N = \frac{Vc \times 1000}{\pi \times 33}$$
- Requirement: High-pressure internal cooling (Min 1.5 MPa) is mandatory for 5D depth.
SP Type U-Drill: Advantages & Considerations
- Uses SPMG square inserts with 4 usable cutting edges (high cost-efficiency).
- Exceptional stability and verticality for deep 5D holes.
- Stronger tool core compared to WC drills, reducing deflection.
- Requires higher spindle power for 33mm diameter.
- Not recommended for machines with low coolant pressure.
Verified Customer Feedback
"Solid Deep Hole Tool"
"Drilling 33mm holes in 45# steel. Body is very rigid, no vibration at full depth."
- Jonathan R. (USA)"Excellent Evacuation"
"The spiral flute is deep and polished. Chips clear easily with through-tool coolant."
- Lukas H. (Germany)"BEYOND Quality"
"Excellent value. Stays straight even at 5D depth."
- Hiro T. (Japan)"Perfect fit"
- Alessandro P. (Italy)
"Highly recommended"
- Francois L. (France)
Technical Support Q&A
Q: What is the benefit of the Side-Lock (C32) shank?
A: The C32 shank allows for massive clamping force, preventing the tool from rotating in the holder during the high-torque demand of a 33mm cut.
Q: Is a pilot hole required for 5D drilling?
A: For maximum precision in 5D depths, we recommend a short 2D U-drill starter hole (approx. 10-20mm) to guide the 5D tool.
Q: Does this include the inserts?
A: No, this is the tool holder only. You can find our compatible high-performance SPMG09 inserts in the "Inserts" category.
Technical Tip: SP vs. WC U-Drills
SP Series (Square): The professional choice for Blind Hole (Blind Bores) because the square insert geometry creates a flatter bottom surface. It offers superior rigidity for deep 5D holes.
WC Series (Trigon): Primarily used for Through Hole applications. WC inserts offer more cutting edges (Trigon shape) but the tool core is 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.
