10-Piece Lightly Used Micro Chip Breaker Carbide PCB Router Set – .0315" to .0512" – Fish Tail & Drill Point – URCV20

This 10-piece lightly used micro chip breaker carbide router set includes five precision cutting configurations, with two tools of each. Cutting diameters range from .0315" (approximately 0.80mm) to .0512" (1.30mm), making the assortment especially useful for fine-detail PCB routing, narrow slots, small cutouts, and prototype work.

These solid carbide routers feature chip breaker flute geometry, which helps break chips into smaller pieces and supports efficient chip evacuation when routing FR-4, G10, fiberglass laminates, and other compatible nonmetallic materials. The set includes both fish tail and drill point tips, providing different entry characteristics for different applications.

What's Included — 10 Pieces, 5 Configurations

Fish Tail vs. Drill Point Tips

Fish Tail Tips: Provide gentler entry into brittle or layered materials, helping reduce chipping and damage during suitable cutting operations.

Drill Point Tips: Offer a durable tip geometry for repeated plunging and applications involving denser materials, where plunge performance and tip strength are important.

Typical Applications

• PCB routing, fine slots, and small board cutouts
• FR-4, G10, fiberglass, and phenolic laminates
• Small-scale CNC routing and prototype fabrication
• Precision trimming of compatible plastics and composites
• Testing different small-diameter router sizes and tip styles

Lightly Used — Excellent Value

These carbide routers were previously used in precision circuit board production, where strict quality and dimensional requirements resulted in tools being removed from service before heavy visible wear. They offer an economical option for hobbyists, prototype shops, educational users, and light industrial applications.

As previously used cutting tools, individual pieces may show minor signs of use. They are not represented as new or guaranteed to perform identically to new production tooling. Inspect tools before use and choose conservative cutting parameters appropriate for your equipment and material.
