Pull Stud JIS B 6339 BT40 with 45° bore (M16) — TECWERK

A Pull Stud JIS B 6339 BT40 with 45° bore engineered for secure tool clamping in BT40 spindles, designed for reliable engagement and straightforward installation

• BT40 taper for standard toolholders
• M16 thread for secure clamping
• 45° conical seat with 4 mm bore

Consistent clamping accuracy for productive machining

The combination of a BT40 taper and an M16 threaded stem provides a mechanically stable interface that reduces axial play and runout. A precise seat geometry ensures repeatable axial location of the toolholder in the spindle, which in turn supports consistent machining tolerances and prolonged cutter life. The compact design is suitable where a reliable connection between spindle and toolholder is required without additional adapter work.

Conical seat and bore support reliable retention

The 45° conical seat creates an immediate axial datum between holder and spindle, while the 4 mm bore allows engagement of puller or retention devices where required. This feature set simplifies removal and handling during tool changes and maintenance. The conical seat geometry distributes clamping forces evenly, helping to maintain concentricity under cutting loads and lowering the likelihood of premature wear on mating surfaces.

Clear dimensional data for easy compatibility checks

Essential dimensions are provided for quick verification: overall length L1: 60 mm, functional length L2: 35 mm, shank diameters d1: 15 mm, d2: 10 mm, d3: 17 mm. These nominal values enable a straightforward compatibility assessment with existing toolholders and retention systems. Where spindle and tooling standards are critical, matching the taper form and thread size is the primary check to ensure safe operation.

Robust choice for workshop stocking and maintenance

A standardised pull stud streamlines toolroom logistics: one compact part can service multiple cutters and holders that accept BT40 tapers and M16 threads, reducing downtime and simplifying inventory management. The simple geometry and clear dimensions support quick inspection and replacement during scheduled maintenance, contributing to a dependable production flow and predictable machine availability.
