Premium 20CrMnTi Alloy & High-Volume Spiral Flutes
Industrial Build: This indexable drill body is forged from superior 20CrMnTi alloy steel and vacuum quenched (HRC 52-55). This core rigidity is essential for large diameter drilling stability and preventing tool deflection. The surface features a Black Oxide finish for superior thermal wear resistance during rapid hole boring cycles.
Advanced Slot Geometry: The tool features an optimized spiral flute (U-groove) specifically engineered to evacuate the high volume of chips produced by a 32mm bore. Integrated internal cooling holes allow high-pressure coolant to flush metal chips directly out of the cutting zone—essential for blind hole machining to prevent chip re-cutting.
Recommended Cutting Parameters (32mm 2D)
Optimal settings for Carbon Steel and Alloy Steel. Adjust based on CNC rigidity and material grade:
Rotation Speed (N) = (Vc × 1000) / (π × 32)
- Cutting Speed (Vc): 100 - 180 m/min
- Feed Rate (f): 0.08 - 0.18 mm/rev
- Coolant: Center-through internal cooling is mandatory.

SP Series Indexable Drill: Advantages & Considerations
- Uses 4-edge SPMG square inserts for lower cost-per-edge.
- Optimized for Blind Hole Machining (Flatter hole bottom profile).
- Thicker body core provides maximum stability for 32mm diameters.
- Requires higher CNC torque compared to WC trigon drills.
- Essential to maintain consistent internal coolant flow and pressure.
Technical Q&A
Q: Why choose SP over WC for blind hole drilling?
A: SP square inserts create a significantly flatter bottom. The SP body is also designed with a thicker core, which is essential for stability in large diameter boring.
Q: Is this tool body compatible with all SPMG09 inserts?
A: It is designed for standard SPMG090408 carbide inserts. Using BEYOND brand inserts is recommended for the best fit.
Q: What is the maximum depth for this 2D drill?
A: The 2D indicates 2x the diameter. For a 32mm drill, the maximum effective drilling depth is 64mm.
Machinist Tip: SP vs. WC U-Drills
SP Series (Square): The professional choice for Blind Hole (Blind Bores). Square inserts create a flatter bottom and offer maximum core strength.
WC Series (Trigon): Primarily used for Through Hole applications. WC inserts offer more edges but the body core is thinner, making it less rigid for 32mm boring tasks.
