7.4mm non-ferrous metals Drilling 2 Flutes Carbide Step Drill with Internal Coolant with Excellent Chip Evacuation
7.4mm Internal Cooling 2-Edge Carbide Step Drill - Efficient Drilling Solution for Non-Ferrous Metals
This 7.4mm internal cooling 2-edge carbide step drill, produced by AMG, is specifically designed for high-precision drilling of non-ferrous metals such as aluminum, copper, and brass. It uses an internal cooling through-hole structure, with straight flute chip evacuation design, offering excellent chip evacuation performance and no burr hole machining
Applications:
Multi-diameter step hole machining for aerospace components
Deep hole and blind hole drilling in non-ferrous fixtures and molds
High-speed CNC drilling in non-ferrous parts with burr-free requirements
Specification Table:
| Parameter | Specification |
|---|---|
| Diameter | 7.4mm |
| Flutes | 2 flutes |
| Flute Type | Straight flute |
| Material | Ultra-fine grain carbide rod |
| Coating | DLC / TiSiN / Customized |
| Coolant Type | Internal coolant through the tool |
| Application | Non-ferrous metals CNC drilling |
working principle:
This step drill adopts an internal cooling design, which directly introduces cooling fluid into the cutting edge area, enhancing cooling efficiency and lubrication capabilities, preventing chip accumulation and tool overheating. The straight flute structure effectively guides the chips out of the hole, making it particularly suitable for soft metals with strong chip adhesion. The step geometry design allows one tool to complete multiple hole diameters, improving machining efficiency and maintaining coaxial accuracy.
Customer purchase demand analysis:
When selecting an appropriate internal coolant step drill, customers often focus on the following :
Type of workpiece material: Is it soft metal such as aluminum alloy, copper, or brass that tends to stick to the cutting tool?
If so, it is recommended to choose the internal cooling + straight groove structure for smoother chip evacuation.
Complexity of hole structure: Is it necessary to process multi-segment stepped holes or deep holes?
If one-time molding or high coaxiality machining is required, a customized stepped structure should be chosed.
Is it continuous batch processing? For applications with requirements on life and stability, it is recommended to use the ultra-fine particle alloy + coating version.
