Kyocera Indexable Grooving Inserts — 105 Genuine SKUs in Stock

Factory-direct supply of 105 genuine Kyocera indexable grooving inserts in stock at CNCHome-Beyond, covering 13 Kyocera series (GDM / GMM / GMG / GBA / VNBR / VNGG / TKN / TTX / XTG and more) and 7 carbide grades (PR1225 / PR930 / PR1215 / PR1115 / PR915 / TN60 / TN90 / KW10). Every insert is original Kyocera Japan stock, ISO 1832 standard compliant, and shipped globally at 30-50% below OEM list price. Kyocera’s grooving series uses the company’s proprietary MEGACOAT CVD coating for steel and an uncoated K-class grade (KW10) for aluminum — a unique combination no other brand offers in a single product line.

What is “Indexable Grooving”?

Indexable grooving is a radial cutting operation on a CNC lathe — the insert feeds inward from the OD toward the centerline of a rotating workpiece. The “indexable” part means the insert has two cutting edges (typical), so you can index (flip) the insert to use the second edge when the first one wears, doubling the tool life per insert vs single-edge designs.

Common applications include:

• O-ring and seal grooves — rectangular or V-shaped recesses that hold rubber O-rings or lip seals in hydraulic cylinders, valve bodies, and bearing housings
• Snap-ring (circlip) grooves — DIN 471/472 standard grooves for internal or external snap rings
• Thread relief undercuts — small grooves at the end of a threaded section to allow the threading die to run out cleanly
• Parting-off (cut-off) — cutting a finished part off the parent bar stock
• Thread whirling — Kyocera’s high-speed thread milling using TKN / TTX / XTG inserts (5-10x faster than thread turning)
• Profile grooving — custom-shaped grooves for O-rings, retaining rings, or decorative features

13 Kyocera Grooving Series in Stock

Kyocera uses a proprietary naming convention (not the standard ISO letter system) for grooving inserts. The 13 series in this collection:

7 Kyocera Grades in Stock

All 105 inserts use Kyocera’s proprietary grade system. The MEGACOAT CVD grades cover steel, the cermet grades cover precision finishing, and the uncoated KW10 covers aluminum — a unique combination only Kyocera offers.

Width and Radius Selection Guide

Grooving inserts are specified by cutting width (W), which must match the groove width. Standard widths:

Compatible Tool Holders

All Kyocera grooving inserts in this collection use the company’s proprietary KGBRF / KGDFR / KGMFR holder series with a top-clamp locking design. Cross-compatible with other brands:

Why Grooving Inserts Need Special Grade Selection

Regular turning inserts (CNMG, DNMG, etc.) cannot be used for grooving for three reasons:

1. Geometry mismatch — turning inserts have a triangular or square cross-section designed for axial cutting, while grooving inserts have a rectangular cross-section with cutting edges on both sides
2. Width specification — grooving inserts are specified by exact cutting width (W = 2.0 mm, 3.0 mm, etc.), turning inserts are not
3. Coolant delivery — grooving holders have internal coolant channels routing high-pressure fluid directly to the cutting edge, while turning holders do not

Kyocera’s grooving series solves all three problems with purpose-built insert geometry, exact width codes (matching standard groove dimensions), and matched high-pressure holders. Do not substitute a turning insert for a grooving insert — the result is immediate insert chipping and likely workpiece scrap.
