10mm Slot Drill DIN 844 Type W HSS-Co8 Short 3-Flute Centre-Cutting 40° Helix, 9.5mm Margin - TECWERK

Take advantage of the combination of durable HSS‑Co8 construction, a secure Weldon shank and a 40° helix for efficient removal of long chips in aluminium and other non‑ferrous metals; order the slot drill directly via Metav Werkzeuge or ask our consultants if needed.

Slot drill DIN 844 Type W – Ø10 mm, HSS‑Co8, Weldon shank (TECWERK)

A short slot drill (DIN 844 Type W) designed for milling long‑chip aluminium and non‑ferrous metals with a secure Weldon shank and three cutting edges

• HSS‑Co8 high‑cobalt tool steel
• 10 mm Weldon cylindrical shank
• Three cutting edges with centre cut
• 40° helix for efficient chip control

High‑precision material and cutting geometry for consistent slot quality

The HSS‑Co8 composition gives the cutter enhanced hot‑hardness and wear resistance compared with standard high‑speed steels, making it a reliable choice for repetitive slotting tasks. Its three cutting edges and centre cut enable stable engagement and predictable chip formation when working with long‑chipping materials. The short overall length and precise geometry reduce vibration in rigid setups, which helps to maintain consistent slot width and surface finish across batches.

Optimised chip evacuation and machining behaviour for aluminium

With a pronounced 40° helix, the cutter promotes smooth chip evacuation and reduces the risk of built‑up edge when machining long‑chip aluminium and other non‑ferrous metals. The right‑hand cutting orientation and centre‑cut feature allow controlled entry into the workpiece, making the tool suitable for slotting and shallow plunge operations where efficient material removal and clean chips are critical for cycle stability.

Secure mounting and torque transmission for reliable production

The Weldon shank (cylindrical shank with driving flat) provides a positive drive and secure clamping in standard toolholders and arbors, minimising slippage under load and improving repeatability. The Ø10 mm shank diameter ensures compatibility with common collet systems while offering a compact interface for fixtures with limited space. This design choice supports short‑run and medium‑run production where tool retention and consistent torque transfer matter.

Short design and cutting length tuned for workshop use

The tool’s short design reduces overhang and increases stiffness at the cutting edge, which benefits accuracy and surface quality in slotting applications. The specified relief/flute length of 9.5 mm indicates the effective cutting zone for slot depths within that range, allowing planners to match the cutter to the intended groove depth and machine set‑up. For machining long‑chip alloys and non‑ferrous components, this cutter balances cutting performance with practical handling in a workshop or CNC cell.

FAQ

What materials is this slot drill suitable for?
The TECWERK slot drill (DIN 844 Type W, SKU 2000866282NW) is optimised for long‑chip aluminium and other non‑ferrous metals, offering very good suitability for these materials.

Can the cutter be used for plunge cutting or drilling operations?
Yes, the centre cut on this short slot drill provides limited plunge capability; the tool is primarily a slotting cutter but can enter the workpiece axially for short plunges.

How does the Weldon shank benefit tooling stability?
The Weldon shank with driving flat ensures positive drive and secure clamping, reducing slippage in toolholders and improving repeatability during slotting operations with the TECWERK cutter.

What is the effective cutting length of the tool?
The effective relief/flute length is 9.5 mm, which defines the practical depth range for clean slotting with this short design.

Is this cutter suitable for CNC machining centres?
Yes, the short configuration, Ø10 mm shank and robust HSS‑Co8 composition make it well suited to CNC milling of grooves and slots in non‑ferrous workpieces where stiffness and chip control are important.
