TECWERK face clamping holder (DIN 69871 Form AD/B) – Weldon 8 mm, SK40

The TECWERK face clamping holder is a SK40 taper clamping arbor designed for coolant-fed milling and drilling operations where tool retention and coolant delivery are essential.

DIN 69871 Form AD/B compatible Central coolant supply with resealable channels Weldon 8 mm clamping for secure axial retention SK40 taper interface with H4 bore tolerance

Consistent fit and repeatability that supports production

The holder conforms to DIN 69871 Form AD/B, ensuring a standardised interface for SK40 spindles and predictable repeatability in serial production. The internal bore is manufactured to H4 tolerance, giving a precise seating that minimises runout and vibration. This level of dimensional control is particularly useful where interchangeability and fixture repeatability matter, as a consistent toolholder interface reduces set-up time and scrap rates while supporting higher spindle speeds with confidence.

Integrated coolant routing to protect tools and workpieces

A built-in central coolant supply with resealable channels at the collar and additional lateral coolant passages offers targeted cooling for tools with cylindrical shanks and a lateral drive surface to DIN 1835‑B. Directed coolant reduces cutting temperatures and improves chip evacuation, which in turn extends tool life and helps preserve surface integrity. The option to reseal coolant channels at the collar also supports maintenance cycles and reduces downtime during tool changes.

Secure clamping and robust mechanical design for demanding tasks

The Weldon-style clamping diameter of 8 mm provides positive axial and rotational restraint for tools with a corresponding flat, supporting torque transmission under load. Combined with a toolholder outer diameter of 28 mm and an installation length A of 50 mm, the assembly balances rigidity with accessibility in compact tool setups. The SK40 taper gives secure mechanical engagement in the spindle while keeping changeover straightforward in machining centres and vertical milling machines.

FAQ

What spindle interface does this holder use?
The face clamping holder uses an SK40 taper compliant with DIN 69871 Form AD/B, suitable for machines equipped with the corresponding spindle taper.

Which clamping diameter is provided for tool retention?
Clamping is designed for an 8 mm Weldon flat; the Weldon 8 mm feature secures tools with a matching flat for reliable torque transmission.

How does the coolant routing improve machining results?
The integrated central coolant supply and lateral channels deliver coolant directly to the cutting zone, reducing thermal load and improving chip evacuation for longer tool life and better surface finish.

Is the bore tolerance adequate for high-precision work?
Yes; the bore is produced to H4 tolerance, offering tight dimensional control that supports low runout and repeatable positioning in production environments.

Which SKU should be referenced when ordering or enquiring?
Please reference SKU 2000833770NW when requesting availability or technical clarification for this TECWERK face clamping holder.
