Complete Guide to Kyocera Cutting Tools: History, Product Lines & Grade Selection
About Kyocera
Kyocera Corporation’s cutting tool division is part of the larger Kyocera Group, a Japanese multinational founded in 1959 by Kazuo Inamori in Kyoto, Japan. Originally named Kyoto Ceramic, the company began by producing fine ceramics (advanced ceramics) for industrial applications. Kyocera entered the cutting tool market in the 1960s with ceramic inserts, leveraging its deep expertise in ceramic materials science. Today, Kyocera’s Industrial Cutting Tools division produces a full range of cemented carbide, cermet, ceramic, and CBN/PCD cutting tools. The company operates manufacturing facilities in Japan, China, Thailand, Mexico, and Germany, serving customers across automotive, aerospace, electronics, and general machining industries. With 21,069 products available on Hooguu, Kyocera offers a diverse and high-quality selection of indexable inserts, solid carbide tools, and toolholders for precision CNC machining.
Kyocera Product Lines
Turning Inserts
Kyocera’s turning insert lineup features the Magic series with precision-molded chipbreakers for excellent chip control across a wide range of feed rates and depths of cut. The Jet Breaker geometry integrates high-pressure coolant delivery channels directly into the insert surface, improving chip evacuation and tool life in sticky materials like stainless steel and Inconel. Popular turning insert shapes include CNMG, WNMG, DNMG, CCMT, and TCMT. Kyocera’s proprietary Megacoat and Megacoat Nano PVD coating technology provides multi-layer TiAlN coatings with nano-structured grain refinement, delivering 30-50% longer tool life than conventional PVD coatings. For finishing, the Kyocera Wiper inserts achieve mirror-finish quality at production feed rates.
Milling Cutters
Kyocera’s milling range includes the MFCN face mill series with 45-degree lead angle for general-purpose face milling. The MEW end mill family provides square shoulder milling capability with helical insert geometry for smooth cutting action. The MFH high-feed mill is designed for mold and die roughing with low cutting forces and high metal removal rates. Kyocera’s Micro Endmill series covers solid carbide end mills from 0.1 mm diameter for micro-machining in electronics and medical device manufacturing. The KMR modular milling system allows quick head changes between face milling, shoulder milling, and slotting operations.
Drilling Tools
The Kyocera Magic Drill (KMD series) is the company’s flagship indexable drill system featuring self-centering insert geometry and internal coolant channels. Available in 2xD, 3xD, and 5xD configurations with diameters from 12 to 50 mm. The KDM solid carbide drill line includes both micro drills (below 3 mm) and standard drills for general-purpose drilling. Kyocera’s Magic Step Drill handles stepped-hole operations in a single pass, reducing cycle times in high-volume automotive production.
Grooving & Threading
Kyocera offers the KGD grooving insert system with double-ended carbide inserts for external and internal grooving operations. Widths range from 1.5 to 6 mm. The KGH system is specifically designed for parting-off with rigid clamping and optimized chipbreaker geometry. For threading, the Kyocera Threading range includes full-profile and partial-profile inserts in both metric (60-degree) and Whitworth (55-degree) forms. The proprietary ZrN coating on threading inserts prevents built-up edge in stainless steel and aluminum threading applications.
