Drill holder E1 (DIN 69871 AD/B) — SK40, central coolant A Drill holder E1 (DIN 69871 AD/B) designed for indexable insert drills with a cylindrical shank and lateral drive flat, suitable for SK40 spindles and applications requiring central coolant. Steep taper DIN 69871 Form AD/B Central coolant supply Re-sealable coolant channels at collar For indexable insert drills, DIN 1835-B shank Precision seating and process compatibility for indexable drilling The holder delivers precise mechanical interface by combining a steep taper conforming to DIN 69871 Form AD/B with a defined clamping arrangement for insert-style drills. With an outer diameter of 45 mm and a 25 mm clamping diameter, the assembly ensures consistent concentricity when accepting tools with a cylindrical shank and lateral drive flat to DIN 1835-B. Bore tolerance H4 at the mounting bore reduces radial play and helps to maintain low runout over repeated tool changes. This mechanical stability translates into predictable hole quality and less scrap in production environments where repeatability matters. Directed coolant and sealed channels for longer insert life Optimised fluid supply is provided through a central coolant supply that feeds cutting edges directly, while re-sealable coolant channels at the collar permit secure routing and leak-free operation when the holder is mounted. Concentrated coolant flow lowers cutting temperature and supports improved chip evacuation for indexable drilling processes. The result is reduced thermal load on inserts and potential for extended tool life, which benefits cycle-time stability and lowers downtime for frequent insert changes. Robust mounting and straightforward integration into CNC spindles Mounting on SK40 spindles is supported by the standard taper and defined dimensions (projection A: 70 mm, outer diameter D: 45 mm), facilitating easy integration into existing tooling systems. The Drill holder E1 is manufactured to maintain positional accuracy under operating loads, helping to stabilise drilling forces and maintain hole tolerance. For workshops and production lines aiming to centralise their tooling supply, the holder’s adherence to DIN standards simplifies procurement and reduces compatibility checks across different machines.

The Drill holder E1 by TECWERK (SKU 2000833053NW) is designed specifically to accept indexable insert drills with a cylindrical shank and lateral drive flat in accordance with DIN 1835-B. How does the coolant system work on this holder? Coolant is fed via the central coolant supply and routed through re-sealable channels at the collar, providing directed flow to the cutting edge to aid cooling and chip control for the TECWERK drill holder. Can this be mounted in an SK40 spindle? Yes, the steep taper conforms to DIN 69871 Form AD/B and the holder is intended for SK40 mounting, ensuring compatibility with standard SK40 spindles. What are the key dimensional tolerances to expect? Key dimensions include a clamping diameter of 25 mm, projection A of 70 mm and outer diameter D of 45 mm; the mounting bore is produced to bore tolerance H4 to maintain concentricity.

52mm Drill Holder E1 DIN 69871 Form AD/B With Coolant Channels, H4 Bore Tolerance - TECWERK
Take advantage of the combination of precise coolant management, a DIN‑standard steep taper and a tight bore tolerance for reliable machining results; order the drill holder directly via Metav Werkzeuge or consult our technical team for application advice. Drill holder E1 (DIN 69871 AD/B) – SK40, 75 mm projection | TECWERK Drill holder E1 provides secure acceptance of indexable‑insert drills with central coolant feed for CNC drilling applications across workshops and production environments Steep taper to DIN 69871 Form AD/B Central coolant supply for internal cooling Re‑sealable coolant channels at the flange For indexable‑insert drills to DIN 1835‑B Maximised rigidity for consistent hole quality The holder is engineered to transfer spindle torque with minimal deflection, delivering consistent hole quality even under repeated cycles. The combination of the SK40 interface and the steep taper per DIN 69871 secures axial and radial stability, which reduces runout and improves tool life. This mechanical rigidity translates into fewer reworks and a more reliable production process when using indexable cutters. Efficient coolant management to extend tool life Integral central coolant supply and re‑sealable coolant channels at the flange allow direct lubricant delivery to the cutting edge, reducing heat and aiding chip evacuation. Focused coolant flow lowers cutting temperatures and diminishes thermal distortion, which in turn lengthens insert life and preserves hole tolerances. The re‑closable channels permit straightforward flushing and maintenance without disassembly, supporting uninterrupted shopfloor operation. Precision fit for indexable‑insert drills and simple integration Designed for acceptance of indexable‑insert drills with a cylindrical shank and lateral drive per DIN 1835‑B, the toolholder provides a precise seating with bore tolerance H4, ensuring repeatable concentricity. The 75 mm projection balances reach and stiffness for moderate overhang drilling, while the external diameter of 52 mm gives a robust clamping interface. Compatibility with standardised shank formats simplifies integration into existing toolholder inventories. Built for workshop reliability and straightforward upkeep The construction focuses on serviceability and uptime: the re‑sealable coolant channels reduce downtime for maintenance, and the standardised form factor supports rapid replacement within CNC tool libraries. Clear adherence to industry standards minimises setup errors and supports systematic tool management. The result is a practical, precision‑oriented solution tailored for manufacturing environments that prioritise reproducible results and operational continuity. For precise CNC drilling with controlled coolant delivery, specify the TECWERK SK40 drill holder E1 and contact Metav Werkzeuge for procurement and technical guidance from Emmerich.
