An Expanding Manual Clutch is a hand-operated internal workholding device that grips components from the inside diameter through mechanical expansion. Actuated by a screw, nut, or taper, it provides secure, uniform internal clamping and is ideal for tool rooms, job shops, prototyping, and small-batch production—especially for thin-wall components where external clamping could cause deformation.
Product Overview
Expanding Manual Clutch is a hand-operated internal clamping device designed to grip components from the inside diameter (ID) by mechanical expansion. Actuation is done manually (screw / nut / taper), causing the expanding sleeve or collet to expand radially and hold the part securely.
It is ideal for tool rooms, job shops, prototypes, and small-batch production, especially for thin-wall components where external (OD) clamping may cause deformation.

An Outer Diameter Clamping Manual Clutch is a hand-operated OD workholding device that grips components on their outside diameter using a manual tightening mechanism such as a nut, lever, or hand wheel. It provides uniform 360° gripping, reliable holding, and simple operation, making it ideal for tool rooms, job shops, prototyping, and small-batch production where power actuation is not required.
A Single Angle Collet Chuck, also known as a Single Taper or Single Cone Collet Chuck, uses one tapered seating surface to clamp the collet uniformly around the workpiece. Valued for its simple, robust, and economical design, it provides reliable 360° gripping and is well suited for tool rooms, job shops, and light-to-medium machining applications where ultra-high precision is not required.
A DIN Collet Chuck is a precision-engineered workholding solution manufactured according to DIN standards, ensuring accuracy, interchangeability, and consistent performance. It provides uniform 360° clamping and good concentricity, making it suitable for CNC machines, conventional lathes, tool rooms, and production setups where standardized tooling and reliable OD clamping or tool holding are required.
An Expanding Collet Chuck (Manual) is a hand-operated internal workholding device that grips components from the inside diameter using a mechanical expansion mechanism. Providing uniform 360° internal clamping, it is ideal for thin-wall parts, rings, bushes, sleeves, and bearing housings in tool rooms, job shops, and small-batch production where power actuation is not required.
A Double Cone Collet Chuck (Manual) is a hand-operated pull-back workholding chuck that uses a dual-taper mechanism to provide strong, uniform 360° clamping with excellent concentricity. Its double-cone design ensures precise centering, high rigidity, and improved surface finish, making it ideal for tool rooms, job shops, and small-batch production where power actuation is not required.
A 5C Collet Chuck (Manual) is a hand-operated pull-back workholding chuck designed for use with standard 5C collets. Operated via a hand nut or lever, it provides uniform 360° clamping, good concentricity, and reliable holding, making it an economical, low-maintenance solution for tool rooms, job shops, and small-batch production where power actuation is not required.
An ER Collet Chuck (Manual) is a hand-operated tool holder designed to clamp cutting tools using ER series collets. Tightened manually with a spanner nut, it provides uniform 360° gripping, good concentricity, and reliable holding, making it an economical and accurate solution for CNC milling, drilling, tapping, and tool room operations without the need for pneumatic or hydraulic systems.
A Traub Collet Chuck (Manual) is a hand-operated workholding device designed for Traub-type collets. Using a manual pull-back mechanism with a nut or hand lever, it provides uniform 360° gripping and good concentricity, making it a simple, economical, and low-maintenance solution for tool rooms, job shops, and small-batch production where power actuation is not required.
