Small-diameter end mills and custom carbide tooling for smartphone housings, heat sinks, connectors, display frames and precision electronic components.
Thin walls, narrow slots, visible surfaces and burr-sensitive interfaces leave little room for unstable tooling. ZIROOTOOLS helps manufacturers match carbide geometry, flute design and tool reach to aluminum, copper, stainless steel, engineering plastics and CFRP applications.
Select the application closest to your part. We can recommend a standard tool or develop a drawing-based custom cutter.

Typical materials: Aluminum alloys, stainless steel, CFRP and engineering plastics.
Machining priorities: Control vibration in thin walls, remove chips from narrow cavities and maintain a clean surface before anodizing or coating.
Tooling approach: Sharp polished flutes, stable neck geometry and application-matched reach help reduce built-up edge, chatter and wall deformation.

Typical materials: Aluminum and copper alloys.
Machining priorities: Deep slots, narrow fins, rapid chip evacuation, low cutting pressure and consistent surface quality.
Tooling approach: Polished carbide end mills and geometry matched to copper or aluminum help limit built-up edge and protect delicate fins.
Micro diameters, sharp edges and rigid tool designs support tight tolerances and burr control in copper alloys, stainless steel and engineering plastics.
Finishing geometry is selected for flatness, decorative edges and visible surfaces on aluminum, stainless steel and reinforced plastics.
For mixed materials, unique profiles and short development cycles, we can evaluate a drawing-based cutter for the feature and machine setup.
Tool selection starts with the feature, material, holder and cutting conditions—not only the tool name.
For aluminum housings, pockets and visible surfaces.
For miniature slots, shoulders and connector features.
For deep cavities and restricted-access features.
For blends, contours and finishing transitions.
For special profiles and combined operations.
Practical tool recommendations built around part geometry, material and production priorities.
Micro features require stable geometry, controlled runout and appropriate chip space.
Edge preparation, flute count and coating are selected for aluminum, copper, stainless steel, plastics or CFRP.
Recommendations focus on surface quality, clean edges and repeatable part consistency.
Special diameters, neck lengths, radii and profiles can be evaluated from your drawing.
Share these details and our team can evaluate the cutting conditions more accurately.
Representative feedback from electronics machining projects and tooling application reviews.
“The polished micro end mills gave us cleaner aluminum housing edges and more stable visible surfaces during finishing trials.”
