Solid Carbide V-Cut & Chamfer Tools for Precision Grooving
Tungsten Carbide V-Groove Milling Cutters
High-precision tungsten carbide V-groove milling cutters for PCB V-CUT, chamfering, deburring, and engraving applications. Solid carbide construction with 20°-120° angles, sub-micron grain, and TiAlN coating options. Custom diameters and angles available.
Product Overview
In precision machining, creating accurate V-shaped grooves, chamfers, and edge preparations requires specialized tooling that maintains dimensional accuracy and surface finish over extended production runs. Our Tungsten Carbide V-Groove Milling Cutters (also known as V-CUT tools, V-slot cutters, or chamfering end mills) are engineered to deliver precise, consistent V-shaped cuts across various materials and applications.
Manufactured from premium solid tungsten carbide with sub-micron grain structure, these tools combine exceptional hardness, wear resistance, and edge retention to achieve clean, burr-free grooves with superior surface finish. Available in angles from 20° to 120° with customizable diameters and lengths.

Frequently Asked Questions
Q1: What is a V-CUT tool used for?
A V-CUT tool is primarily used in PCB manufacturing to cut V-shaped grooves on printed circuit boards, enabling easy panel separation. It is also used for chamfering, deburring, and engraving applications.
Q2: What coating should I choose for my application?
For general-purpose machining of steel and stainless steel, TiN coating is recommended. For high-speed machining and hard materials, TiAlN or AlTiN coatings provide superior heat resistance and wear resistance.
Q3: Can you manufacture custom V-groove cutters with specific angles and diameters?
Yes. We manufacture V-groove milling cutters to your exact specifications, including custom V-angles, diameters, lengths, and flute configurations. Please provide your drawing or requirements for a prompt quote.
