Description
Product Overview
The 3 Pack SPT045HS THINBIT LITTLEBIT S Series Parting Insert is engineered by Kaiser Tool Company to meet the demanding requirements of modern machining environments. Constructed from uncoated high speed steel (HSS), the insert delivers exceptional hardness and wear resistance, allowing it to cut through plastics, composite materials, and abrasive workpieces without premature degradation. Its compact dimensions—1 x 0.07 x 0.24 inches—provide a narrow cutting profile that minimizes material loss and reduces part deflection, making it ideal for precision parting of thin‑walled tubing and small‑diameter components. The insert is compatible with Small series toolholders, ensuring a secure fit and consistent performance across a range of CNC and manual machines. With a best‑seller rank of #71 in the Parting Inserts category, this product has proven its reliability among industrial users seeking high‑speed, low‑RPM cutting solutions.

Usage
Designed for versatility, the SPT045HS insert excels in a variety of applications. It is particularly effective when parting solid stock up to 1.000″ in diameter or tubing with wall thicknesses up to .500″. The thin width enables cuts within 1/16″ of the collet face, allowing operators to achieve tight tolerances on precious metals, aerospace alloys, and delicate polymer components. Its uncoated HSS composition tolerates abrasive cutting conditions, making it suitable for machining composites, reinforced plastics, and even low‑RPM operations where heat buildup can be a concern. Users in automotive, aerospace, and medical device manufacturing will find the insert’s ability to maintain dimensional stability under high stress especially valuable.
