IMPA: 632922

Cemented Carbide Tips Model 04 (IMPA 632922)

These cemented carbide tips (IMPA 632922) are precision-engineered cutting inserts designed for demanding marine and industrial machining applications. The Model 04 geometry offers a balanced combination of toughness and edge strength, making them ideal for turning, boring, threading, and grooving on lathe equipment used in ship repair and fabrication shops.

Manufactured from high-grade tungsten carbide with a tough cobalt binder, these tips deliver exceptional wear resistance, thermal stability, and consistent cutting performance even under heavy loads. Each insert is precision ground to maintain tight tolerances, ensuring repeatable machining results. Whether you are machining steel, stainless steel, cast iron, or non-ferrous alloys, these tips provide reliable service in both roughing and finishing operations.

As a trusted ship chandler product, these cemented carbide tips meet the international IMPA standard for cutting tools, making them an essential stock item for ships and marine workshops. Their standardized size and mounting style allow quick indexing and secure clamping in compatible tool holders, minimizing downtime and maximizing productivity.

Frequently Asked Questions

What materials can these cemented carbide tips cut?

These tips are designed for machining steel, stainless steel, cast iron, and non-ferrous alloys. The specific carbide grade should be selected based on the workpiece material and cutting conditions.

Are these tips suitable for marine engine repair?

Yes, they are commonly used in ship repair workshops for turning and boring shafts, impellers, liners, and other components. Their wear resistance and thermal stability make them reliable for heavy-duty marine machining.

Do Model 04 tips fit standard tool holders?

Model 04 refers to a standardized insert size and geometry. As long as the tool holder accommodates the same ISO insert designation and clamping style, the tips will fit. Always verify compatibility before installation.

Can these tips be re-sharpened?

These are indexable inserts; when one cutting edge wears, the insert can be rotated to a fresh edge. Once all edges are worn, the tip should be replaced. Regrinding is possible but not recommended, as it may affect the coating and geometric tolerances.
