KYOCERA Cera-Notch Grooving Insert KCGDP3125L PR930 Carbide

Description

Product Overview

The KYOCERA KCGDP3125L PR930 Cera-Notch grooving insert is a premium indexable insert designed for high‑precision face grooving applications. Constructed from a proprietary carbide‑TiCN blend, the insert offers a unique balance of hardness and toughness, allowing it to maintain a sharp cutting edge even under the most demanding machining conditions. The 0.008‑inch corner radius provides a fine, smooth transition that reduces stress concentrations on the workpiece, while the left‑hand configuration ensures optimal chip evacuation for left‑handed tool setups. With a groove width of 0.125 inches and two cutting edges, this insert delivers consistent material removal rates and superior surface finishes across a wide range of alloys, including hardened steels, stainless steels, and exotic materials such as Inconel and titanium alloys.

Dimensions are carefully controlled to meet the KCGDP series specifications: the insert measures 3.125 mm in width, 5.0 mm in length, and 2.5 mm in thickness, providing a compact footprint that fits standard indexable tool holders. The PR930 grade designation indicates a high‑performance grade within the Kyocera product line, offering enhanced wear resistance and longer tool life compared to standard grades. The Cera‑Notch geometry incorporates a specially engineered notch that promotes chip breakage and reduces the likelihood of chip recirculation, which can otherwise lead to surface defects and premature tool wear.

Usage

This insert is ideally suited for CNC milling machines, high‑speed machining centers, and conventional machining setups where precise face grooving is required. It excels in applications such as gear tooth preparation, keyway machining, and the creation of sealing grooves on hydraulic components. The left‑hand orientation makes it a perfect match for tools that rotate clockwise, allowing operators to achieve clean, burr‑free grooves with minimal post‑processing.

When used in conjunction with a rigid tool holder and proper coolant delivery, the KCGDP3125L PR930 insert can sustain high cutting speeds of up to 300 m/min and feed rates of 0.1 mm/rev, depending on the material being machined. Its robust carbide‑TiCN composition tolerates the elevated temperatures generated during high‑speed cutting, reducing the risk of thermal cracking and preserving dimensional accuracy throughout the machining cycle. For optimal performance, it is recommended to use a cutting fluid with high lubricity and cooling capability, such as a water‑soluble emulsion or a synthetic oil, to further extend tool life and improve surface finish.

Operators in aerospace, automotive, and precision engineering sectors will find this insert particularly valuable when machining components that demand tight tolerances and flawless surface integrity. The insert’s ability to produce consistent groove widths and depths helps maintain assembly fit and function, which is critical in applications like turbine blade sealing, valve seat preparation, and high‑pressure fluid system components.

FAQ

What materials can this insert machine effectively?

The KCGDP3125L PR930 is designed to handle a broad spectrum of materials, including hardened steels up to 60 HRC, stainless steels, nickel‑based alloys such as Inconel, and titanium alloys. Its carbide‑TiCN matrix provides the hardness needed for abrasive materials while retaining enough toughness to avoid chipping on tougher alloys.

How do I determine the optimal cutting speed and feed rate?

Optimal parameters depend on the workpiece material, machine rigidity, and coolant usage. As a starting point, for medium‑carbon steel, a cutting speed of 250 m/min and a feed rate of 0.08 mm/rev are recommended. For harder alloys, reduce the speed to 180‑200 m/min and adjust the feed accordingly. Always refer to the machine’s capability chart and perform a trial cut to fine‑tune the settings.

Can this insert be used in high‑speed machining centers?

Yes. The carbide‑TiCN composition is specifically engineered to withstand the elevated temperatures generated in high‑speed machining. When paired with appropriate coolant delivery and a rigid tool holder, the insert can operate at speeds up to 300 m/min, delivering high material removal rates without compromising edge integrity.

What is the recommended method for inserting the tool into the holder?

Use a precision indexable holder that matches the KCGDP series dimensions. Align the insert’s indexing key with the holder’s slot, apply a uniform torque as specified by the holder manufacturer (typically 0.5‑0.7 Nm), and verify the seating with a feeler gauge to ensure no play. Proper installation prevents premature wear and maintains the designed cutting geometry.

Is there a warranty or after‑sales service for this product?

Kyocera provides a one‑year limited warranty against manufacturing defects for the KCGDP3125L PR930 insert. In addition, our technical support team is available to assist with tool selection, machining optimization, and any issues that arise during use. Replacement parts are stocked in major distribution centers for quick turnaround.
