High-Grade Material & Precision Flute Geometry
Premium Body Construction: This WC indexable drill is crafted from high-performance 20CrMnTi alloy steel. Through vacuum quenching, the body achieves exceptional toughness and surface hardness ($$HRC 50-55$$), providing superior resistance to vibration during high-speed boring.
Spiral Flute & Chip Breaker: The SD33.5 U-drill body features a precision-ground spiral flute designed for rapid chip evacuation. The optimized flute geometry reduces friction and prevents heat buildup. Integrated internal coolant channels ensure that chips are flushed away immediately, extending the tool life of your WCMX / WCMT carbide inserts.
Recommended Cutting Parameters
Achieve optimal results for your 33.5mm hole making with these settings:
- Cutting Speed (Vc): 100 - 180 m/min (Steel), 120 - 220 m/min (Alloy).
- Feed Rate (f): 0.06 - 0.15 mm/rev.
- Rotation Speed (N): Calculated as $$N = \frac{Vc \times 1000}{\pi \times 33.5}$$
- Coolant Strategy: Internal cooling is mandatory to clear chips efficiently.
WC Type U-Drill: Advantages & Considerations
- Uses WC series trigon inserts (3 cutting edges - cost-effective).
- Fast drilling speed with excellent hole surface finish.
- Stable entry on curved or uneven workpiece surfaces.
- Requires high spindle power compared to twist drills.
- Typical hole tolerance (+0.1 / -0.2mm); not for H7 precision.

Frequently Asked Questions
Q: Does the drill body include the WCMX inserts?
A: No, the price is for the 33.5mm U-drill body only. Inserts must be purchased separately.
Q: Can I use this for blind holes?
A: Yes, it is excellent for both through-holes and blind-holes in steel and stainless steel.
Q: What is the benefit of the 2D length?
A: 2D drills offer the highest rigidity, reducing deflection and allowing for faster feed rates compared to 3D or 5D versions.
Drilling Depth Selection: 2D-5D Comparison
Choosing the right depth-to-diameter ratio is critical for tool life:
- 2D (This Model): Max rigidity. Best for general shallow holes and high-feed roughing.
- 3D: Standard versatility for most industrial boring tasks.
- 4D-5D: Deep hole specialized. Requires higher coolant pressure and reduced feed rates to avoid tool breakage.

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.
