Material & Flute Geometry Analysis
Premium Body Material: Constructed from high-performance quenched alloy steel (20CrMnTi), this 60mm indexable drill is built to withstand extreme torque. The surface is nickel-plated to prevent chip welding and enhance tool life.
Optimized Spiral Flute: The large-capacity spiral flute is designed for efficient "forced" chip evacuation. By utilizing a specific chip-breaker flute geometry, it prevents chip packing, which is a common failure point in large-diameter drilling.
Recommended Cutting Parameters
For optimal performance of the 60mm U-drill, please follow these baseline settings:
- Cutting Speed (Vc): 100 - 180 m/min (Depending on material hardness).
- Feed Rate (f): 0.08 - 0.20 mm/rev.
- Spindle Speed (N): Calculated via $$N = \frac{Vc \times 1000}{\pi \times 60}$$
- Note: High-pressure internal cooling is required for a 60mm cut to ensure chip flushing.
WC Type U-Drill: Pros & Cons
- Uses WCMX / WCMT inserts with 3 usable cutting edges (Very economical).
- Stable entry even on rough surfaces or slanted faces.
- Lower cutting resistance compared to square insert drills.
- Requires high spindle horsepower (kW) for 60mm diameters.
- Dimensional tolerance (+0.1/-0.2mm) is for roughing before finishing.

Frequently Asked Questions
Q: Is this drill suitable for blind holes?
A: Yes, it is ideal for both through-holes and blind holes due to its flat-bottom profile and efficient chip evacuation.
Q: What machine power do I need for a 60mm U-drill?
A: A 60mm diameter requires significant torque. We recommend machines with at least 15kW spindle power for stable operation.
Q: Does the package include the screws and wrench?
A: Yes, the body comes with the insert screws and the correct Torx wrench included.
Pro-Tip: 2D vs. 5D Depth Selection
2D Drill (This Model): Offers maximum rigidity and shortest cycle times for shallow holes up to 120mm deep. Best for accuracy.
3D-5D Drills: Designed for deeper holes. They require much higher coolant pressure and slower feed rates to prevent vibration and ensure chip clearance.

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.
