SPT025HS Kaiser THINBIT LITTLEBIT S Parting Insert Uncoated HSS

Description

Product Overview

The SPT025HS THINBIT LITTLEBIT “S” Series parting insert is engineered by Kaiser Tool Company to meet the rigorous demands of modern machining environments. Constructed from uncoated high speed steel (HSS), this indexable insert delivers exceptional wear resistance and edge retention when cutting plastics, composites, and abrasive materials. Its compact dimensions—0.65 x 0.07 x 0.24 inches—allow it to fit into Small series toolholders, providing a low‑profile solution that reduces material loss and part deflection. The insert’s narrow width is specifically designed for precision work on thin‑wall tubing, small‑diameter components, and precious metal parts where every thousandth of an inch matters. With a parting capability of up to .400″ solid stock and .200″ wall‑thick tubing, the SPT025HS offers versatile performance across a broad range of applications, from aerospace component fabrication to jewelry manufacturing.

Usage

Designed for low‑RPM cutting conditions, this insert excels in environments where speed and stability are critical. It is ideal for parting operations on plastics such as acrylic, polycarbonate, and engineering polymers, as well as composite laminates that demand consistent chip formation. The thin width enables cuts within 1/16″ of a collet face or shoulder of a larger diameter, making it perfect for machining thin‑wall tubing used in medical devices, fluid delivery systems, and high‑precision instrumentation. Users can pair the insert with Small series toolholders to achieve tight tolerances and reduced vibration, ensuring smooth, burr‑free finishes on delicate workpieces. Its robust HSS composition also tolerates abusive cutting conditions, providing reliable performance even when machining abrasive composites or reinforced plastics.
