Weldon end mill holder SK40 – 18 mm clamping, 63 mm projection (TECWERK)

A Weldon end mill holder for SK40 spindles, designed to accept cylindrical-shank tools with lateral drive faces for precision milling tasks

• Weldon flat for secure lateral drive
• SK40 taper to DIN 69871 Form AD
• 18 mm clamping diameter with H4 bore
• 63 mm projection for extended reach

Precision compatibility for standard milling systems

The holder is built to the DIN 69871 Form AD standard and mates with SK40 spindles, ensuring consistent interface geometry across machines. The steep taper provides stable seating and repeatable axial location, while the 18 mm clamping diameter and H4 bore tolerance guarantee a tight fit for tools with a cylindrical shank to DIN 1835‑B. This standardised compatibility reduces setup time and simplifies tooling management in production environments, enabling predictable tool positioning and helping to maintain machining tolerances.

Secure tool retention and reduced runout for consistent cuts

A defining technical advantage is the Weldon flat, which provides lateral drive and prevents rotational slippage under high cutting forces. Combined with the robust taper connection, this design improves tool retention and contributes to lower runout, translating into better surface finish and longer tool life. The 63 mm projection balances accessibility and rigidity: a longer reach where needed without excessively compromising stiffness. For workshops seeking dependable milling performance, the combination of secure lateral drive and precise taper seating supports stable, efficient material removal.

Practical workshop benefits and supply reliability

Integration into an existing tooling system is straightforward thanks to conformity with common standards for milling holders and tool shanks. The component’s compatibility with DIN 1835‑B tooling simplifies inventory choices and changeovers on the shop floor. Metav’s distribution model emphasises dependable supply from Emmerich and knowledgeable technical advice, shortening lead times and reducing procurement friction. The robust construction and standards compliance mean fewer interruptions in production and predictable maintenance cycles, helping teams focus on throughput and product quality.
