3.00mm (.1181") CVD Diamond-Coated PCB Router, .472" LOC, Drill Point, 3mm Shank | K155

Kyocera 3.00mm CVD Diamond-Coated Router | 12mm LOC | Drill Point | Up-Cut | K155

The K155 Kyocera CVD diamond-coated diamond-flute router features a 3.00mm (0.1181") cutting diameter, 12.00mm (0.472") length of cut, 38.00mm overall length, and 3.00mm shank. Made in the USA, this precision solid carbide router combines diamond-pattern cutting geometry with a CVD diamond coating for demanding machining applications involving carbon fiber, fiberglass, and other abrasive composites.

The CVD (Chemical Vapor Deposition) diamond coating provides a highly wear-resistant surface that helps protect the carbide cutting edges from abrasive wear. This makes K155 particularly useful for CFRP and fiberglass-reinforced materials that can quickly wear conventional uncoated carbide tooling.

Key Features

• 3.00mm (0.1181") cutting diameter: Suitable for precision composite profiling, slots, contours, and cutouts
• CVD diamond coating: Provides excellent resistance to abrasive wear when machining carbon-fiber and fiberglass composites
• Diamond-pattern flute geometry: Numerous intersecting cutting edges provide distributed cutting engagement in abrasive, fiber-reinforced materials
• Drill-point tip: End-cutting geometry supports controlled entry and plunging under appropriate machining conditions
• Up-cut design: Helps direct chips and cutting debris upward during routing
• 12.00mm LOC: Extended cutting reach for suitable composite sheets and panels
• Micrograin solid carbide substrate: Provides tool rigidity beneath the diamond coating
• 3.00mm shank: Designed for compatible 3mm precision spindle collets and tool holders
• Kyocera manufacturing: USA-made precision cutting tool

CVD Diamond Coating for Abrasive Composites

Carbon-fiber reinforced polymer (CFRP), fiberglass, and similar composite materials contain abrasive reinforcing fibers that accelerate cutting-edge wear. K155 uses a CVD diamond coating over its solid carbide substrate to improve wear resistance in these demanding applications.

Unlike an uncoated diamond-flute router, which takes its name from the intersecting cutting-edge pattern, K155 combines diamond-flute geometry with an actual diamond coating.

The coating can provide substantial tool-life advantages over uncoated carbide when machining suitable abrasive materials. Actual performance depends on workpiece composition, tool engagement, spindle runout, cutting conditions, and coating integrity.

Drill-Point Tip & Up-Cut Geometry

The drill-point tip provides a pointed end-cutting profile for entry into suitable composite materials. It can be useful when machining internal contours, slots, and cutouts.

Because diamond coatings can be sensitive to impact and excessive loading, controlled entry, ramping where appropriate, and properly selected plunge parameters are important. Avoid sudden, aggressive plunging unless the cutting conditions are supported by the tooling application.

The up-cut geometry helps move chips and routing debris toward the upper surface of the workpiece. Effective dust extraction and secure workholding are important when routing carbon fiber and fiberglass.

Typical Applications

• CNC routing and profiling of carbon-fiber reinforced polymer (CFRP)
• Carbon-fiber sheet and laminate trimming
• Fiberglass-reinforced composite machining
• G10 and FR4 fiberglass/epoxy laminates
• Composite panel slots, contours, and internal cutouts
• Precision machining of abrasive fiber-reinforced plastics
• Production applications where improved wear resistance can reduce tool changes

Technical Specifications

Machining Recommendations

Use a rigid CNC machine, an accurately sized 3mm collet, low spindle runout, and secure workholding. Select feed rate, spindle speed, entry method, and cutting depth according to the composite material and CVD-coated tool geometry.

For coated tooling, use manufacturer-recommended cutting parameters whenever available. Standard uncoated carbide feed-and-speed charts should not be treated as verified operating settings for this CVD-coated router. Use effective dust extraction and suitable personal protective equipment when machining carbon fiber or fiberglass.
