Inserts for hole-making

Suitable for machining low carbon and soft stainless steels, the SD geometry supports both Dormer Pramet’s SCET and XPET ranges.

The SD (soft drilling) chip breaker has been designed to provide improved stability and productivity when drilling low strength soft and long-chipping material, where the balance of forces between the inserts becomes more difficult to maintain. 

Part of a wider launch of new products announced by Dormer Pramet, the chip-breaker’s positive geometry with stabiliser is said to provide reliable chip evacuation, minimal vibration and low cutting forces. This results in a quieter and more stable machining process.
