TECWERK pull stud — ISO 7388/II Form B, SK40 with bore (M16)

The TECWERK pull stud ISO 7388/II Form B is a precision retention component for SK40 spindle systems, engineered to ensure consistent drawbar clamping in CNC and machining-centre applications.

• ISO 7388 / II Form B standard compatibility
• SK40 taper for reliable spindle fit
• M16 thread for positive drawbar connection
• Central bore for drawbar/coolant access

Consistent clamping through standard conformity

Compliance with ISO 7388 / II and the Form B geometry guarantees interchangeability with other standard retention systems and supports reproducible clamping forces. The standardised interface reduces uncertainty at tool change, so toolholding performance is predictable and can be integrated into production planning. With the SK40 taper and M16 thread specified, the component is suited to established spindle toolholders, enabling simplified spare-part management and shorter downtimes.

Secure drawbar engagement and straightforward functionality

The retention stud features a central bore that permits unobstructed drawbar engagement and may be used in systems where internal coolant or lubrication paths are required. The stud’s geometry — including d1: 18.95 mm, d2: 12.95 mm and d3: 17 mm — is designed to interface precisely with mating drawbar mechanisms, so axial retention and torque transmission are maintained during heavy machining tasks. This technical layout supports stable tool retention, which is vital for repeatable machining accuracy.

Precise dimensions for repeatable accuracy

Key dimensions such as L1: 44.5 mm and L2: 16.4 mm define the effective length and engagement depth, helping to control stick-out and tool projection consistently across setups. The clear numerical specifications allow planners and engineers to verify compatibility with existing holders and spindles before purchase. By basing decisions on measurable values rather than estimates, workflow reliability is improved and setup variation is minimised.

Practical integration into workshop workflows

The compact design and standardised threading ensure this retention stud slots into conventional SK40 toolholding systems with minimal modification. As a delivery-ready industrial part, it supports inventory rationalisation for production and maintenance departments, reducing the variety of special components required.

FAQ

Which standard does this pull stud conform to?
The TECWERK pull stud is manufactured to ISO 7388 / II Form B and is intended for use where that standard is specified, reference SKU 2000832720NW.

Is the retention stud compatible with SK40 spindles?
Yes — the component is specified for SK40 taper interfaces and uses an M16 thread for drawbar engagement, suitable for standard SK40 toolholding systems.

What is the purpose of the central bore in this design?
The central bore enables secure drawbar engagement and can allow internal coolant or lubrication routing where the machine’s spindle and toolholder design provide such functionality.

What are the critical dimensions to check for compatibility?
Key dimensions to verify are d1: 18.95 mm, d2: 12.95 mm, L1: 44.5 mm and L2: 16.4 mm; these define the engagement geometry of the TECWERK pull stud (SKU 2000832720NW).
