Material & Flute Geometry Analysis
Premium Alloy Steel: The 46mm U-drill body is manufactured from hardened alloy steel (20CrMnTi), featuring a nickel-plated surface to prevent chip welding and increase wear resistance during high-torque boring.
Optimized Chip-Breaker Flute: This tool utilizes a spiral flute geometry designed for efficient chip evacuation. The internal coolant channels allow high-pressure fluid to flush out metal chips directly from the cutting zone, reducing heat buildup and preventing tool failure in deep hole boring.
Recommended Cutting Parameters
For the best results with the BEYOND 46mm indexable drill, follow these baseline recommendations:
- Cutting Speed (Vc): 110 - 180 m/min (Depending on material).
- Feed Rate (f): 0.08 - 0.20 mm/rev.
- Rotation Speed (N): Calculated via $$N = \frac{Vc \times 1000}{\pi \times 46}$$
- Coolant: Internal cooling is highly recommended for 46mm diameters.
WC Type U-Drill: Pros & Cons
- Uses WCMX / WCMT inserts with 3 cutting edges (Economic choice).
- Lower cutting resistance than square insert drills.
- Stable entry on rough surfaces.
- Requires high-power CNC spindles for a 46mm cut.
- Roughing tolerance (+0.1/-0.2mm); not for precision finishing.

Frequently Asked Questions
Q: Does this drill include the carbide inserts?
A: No, this is the 46mm drill body only. Inserts must be purchased separately.
Q: Is this drill compatible with high-pressure coolant?
A: Yes, it is designed with internal cooling ports specifically for high-pressure systems to flush chips efficiently.
Q: What is the benefit of the 2D length?
A: 2D drills provide the highest rigidity, making them ideal for short, large-diameter holes where precision is key.
Pro-Tip: Choosing Drill Depth (2D vs 5D)
2D Model (This tool): Best for stability and shorter holes (up to 92mm depth). Higher resistance to deflection.
3D to 5D Models: Necessary for deep boring but requires significantly higher coolant pressure and more conservative feed rates to avoid vibration and chip clogging.

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.
