Quick-change insert SES 18 mm x 14.5 mm – Size 3, adjustable safety clutch (TECWERK)

The Quick-change insert SES 18 mm x 14.5 mm Size 3 is a tap adapter with an adjustable safety clutch for torque limitation, designed for use with DIN 374/376 M22 threading applications.

• Adjustable safety clutch for torque limiting
• Prevents tap breakage during interrupted cuts
• Shaft-square drive for reliable torque transmission
• Compatible with DIN 374/376 M22 tap sizes

Faster, safer threading through adjustable torque control

The integrated adjustable safety clutch enables precise limitation of applied torque, which reduces the risk of tool failure during threading. By disengaging at a preset torque level, the clutch protects the tap from snap-off in interrupted or snagging threads, improving uptime and reducing consumable costs. This mechanical protection is particularly valuable in repetitive production environments where unexpected torque spikes otherwise require frequent tap replacement and interrupt workflow.

Compact Size 3 form factor that fits standard tap holders

Designed as a Size 3 quick-change insert, the component fits into common tap-change systems and mates with holders prepared for DIN 374/376 M22. The compact geometry preserves bench space and simplifies tool inventory: different shank sizes can be accommodated by swapping appropriate inserts, maintaining a small stock of adapters while covering multiple tap shank dimensions. The adapter’s construction focuses on a secure interface and repeatable positioning to ensure consistent thread quality across batches.

Direct torque transfer via shaft square for dependable performance

Torque is transmitted through the shaft square, ensuring a positive mechanical drive between machine and tap. This avoids slippage under load and enables efficient power transfer even in high-demand machining cycles. The device’s dimensions (including L3, L4 and D values) have been optimised to balance rigidity and accessibility, allowing the tap to reach into confined thread depths without compromising control or safety. The result is reliable, repeatable threading that supports process stability.

Practical benefits for workshop and industrial users

By preventing tap breakage and simplifying insert changes, this adapter contributes to measurable efficiency gains on the production floor. Reduced downtime from fewer tool failures and faster insert swaps improves throughput while lowering tool consumption. Backed by established industrial standards compatibility, the insert offers a pragmatic solution for workshops and maintenance departments that require robust tap protection and straightforward integration into existing quick-change systems.

FAQ

Is this insert compatible with standard M22 taps to DIN 374/376?
Yes. The SES quick-change insert is specified for DIN 374/376 M22 and is designed to accept taps made to that standard.

How does the adjustable clutch protect taps during threading?
The adjustable safety clutch in the SES insert disengages at a preset torque, limiting peak loads and thereby reducing the likelihood of tap breakage during sudden jams or interrupted cuts.

Which shank sizes are supported by this Size 3 insert?
The insert transmits torque via a 14.5 mm shaft square; for other shank dimensions, alternative inserts are required to match the specific holder and tap shank.

Can the insert be used in automated tapping stations?
Yes. With its direct shaft-square torque transmission and compact dimensions, the insert is suitable for integration into automated and manual tapping stations that accept Size 3 quick-change adapters.

What are the key dimensions to check for fitment?
Refer to the SES insert dimensions: diameter 18 mm, square 14.5 mm, and the listed L1, L3, L4, L5 and D measurements to verify compatibility with the tool holder and required thread depth.
