3/8" ID x 3/4" OD Boring & Grooving Bar Holders MPN:QHC75-3/8

The 3/8 ID x 3/4 OD Boring and Grooving Bar Holders are precision engineered cutting tools designed for use with scientific cutting tools or any machine tool capable of handling the appropriate shank size. Its unique bushing design allows it to accept standard round bars with an inside diameter (I.D.) of 3/8, making it compatible with various sizes and styles of scientific cutters, providing versatility in tasks. Additionally, the bar holder has a 1/4 through-hole on both ends to allow air or fluid passage when cutting soft materials like wood, paper or nonwoven fabric films that require vacuum or hydraulic clamping techniques while preserving excellent stability during operation. The hardened steel construction ensures high durability and rigidity while preventing warping even under heavy loads. Suitable for laboratories, manufacturing facilities and universities, these boring bar holders contribute to precise cutting with scientific cutters by securing them firmly in place when used on milling machines, lathes or other compatible CNC machines, resulting in superior cutting quality for a wide range of materials.
