Customized Tungsten Solid Carbide Step mill drill CNC Cutting Tool

Introduction:

A customized tungsten solid carbide step mill drill is a high-precision, multi-functional CNC cutting tool designed for step milling, drilling, chamfering, and countersinking in a single operation. It is widely used in aerospace, automotive, mold-making, and precision engineering for efficient material removal with tight tolerances.

Features:

Solid Tungsten Carbide Construction

• Ultra-hard & wear-resistant for long tool life in tough materials (steel, stainless, titanium, composites).

• Maintains sharp cutting edges even at high RPMs.

Multi-Functional Step Design

• Combines drilling, milling, and chamfering in one tool, reducing tool changes & cycle time.

• Multiple step diameters for tapered holes, counterbores, and stepped profiles.

Custom Geometry Options

• Adjustable step lengths & diameters (tailored to part requirements).

• Variable flute counts (2-4 flutes) for optimized chip evacuation.

• Coating choices (TiN, TiCN, TiAlN, DLC) for specific materials.

High-Speed & High-Feed Capable

• Optimized helix angle for smooth chip flow & reduced heat buildup.

• Suitable for high-speed machining (HSM) & hard milling (up to HRC 60+).

Precision Ground Cutting Edges

• CNC-ground for micron-level accuracy (±0.005mm tolerance available).

• Reduced runout for better hole quality & surface finish.

Typical Applications:

✔ Aerospace (Turbine blades, structural components)
✔ Automotive (Engine blocks, transmission parts)
✔ Mold & Die (Cavity machining, ejector pin holes)
✔ Medical Devices (Bone screws, implants, surgical tools)
✔ Electronics (PCB drilling, precision housings)
