Take advantage of the combination of robust HSS‑Co8 construction, three‑flute centre‑cut geometry and a Weldon shank for stable groove milling in long‑chip aluminium and other non‑ferrous metals; order directly via Metav Werkzeuge or consult our specialists for process integration.

TECWERK slot drill DIN 844 Type W — 10 mm, HSS‑Co8, Weldon shank

The TECWERK slot drill DIN 844 Type W is a short, three‑flute, centre‑cutting cutter designed for milling grooves and plunge operations in long‑chip aluminium and non‑ferrous metals.

• HSS‑Co8 high‑alloy high‑speed steel
• Three‑flute centre‑cut design
• Weldon shank Ø10 mm
• Excellent for aluminium and non‑ferrous metals

Rigidity and material combination for repeatable groove quality

Constructed from HSS‑Co8, the cutter provides a balance of hardness and toughness that suits frequent metal‑removal in softer, long‑chip materials. The three‑flute layout offers a compromise between chip space and cutting edge stability, while the centre‑cutting geometry allows controlled plunging and pocket entry without prior peck drilling. For production workflows this translates into consistent groove geometry and fewer secondary operations, making the tool appropriate for series work on aluminium and similar non‑ferrous alloys.

Faster cutting with efficient chip control

A 40° helix angle promotes smooth chip evacuation when machining long, stringy swarf typical of aluminium. The short design increases torsional stiffness, reducing chatter and improving surface finish at higher feed rates. The tool’s relief‑ground length of 9.5 mm and cutting length of 3 mm are configured to manage chip flow within the flute volume, minimising built‑up edge and frequency of stoppages for cleaning. These technical choices deliver improved machinability and shorter cycle times in interrupted or continuous slotting operations.

Secure holding and machine compatibility for reliable set‑ups

The Weldon shank with driving flat ensures positive torque transmission in standard holders and reduces slippage under load, while the Ø10 mm shank fits common collets and toolholders found in small to medium machining centres. Compliance with DIN 844 Type W guarantees dimensional and interface uniformity, simplifying tool change and inventory management. The overall length and effective length settings favour rigid clamping and reduce overhang, enhancing tool life and runout control during heavier engagement.

Practical guidance for process integration and maintenance

When integrating this cutter into a production cell, select feeds and speeds aligned with aluminium machining practice and maintain consistent coolant or air blast to aid chip evacuation. The short, centre‑cut geometry supports plunge‑milling without additional pre‑drilling for shallow features; however, trial cuts on representative stock are recommended to establish optimal parameters. Regular inspection of the three cutting edges for wear and edge rounding will extend service intervals and maintain part quality. For applications beyond non‑ferrous metals, consult material‑specific recommendations before use.

FAQ

What materials is this cutter suitable for?
The cutter is very well suited for long‑chip aluminium and other non‑ferrous metals; the HSS‑Co8 composition gives the tool the toughness and wear resistance required for these materials.

Does the tool allow plunging or entry without pre‑drilling?
Yes, the centre‑cutting geometry enables controlled plunging and pocket entry, so the slot drill can be used for shallow plunge operations when appropriate feeds are applied.

What is the shank type and how is it held?
The tool features a Weldon shank with driving flat and a 10 mm shank diameter, designed for secure clamping in standard Weldon holders and collets.

How many flutes does the cutter have and why does that matter?
This is a three‑flute cutter; the configuration balances chip clearance and cutting edge stability, which benefits groove finish and tool life in long‑chip materials.

Can this tool be used on harder metals?
The tool is optimised for non‑ferrous and long‑chip materials; for harder steels or hardened alloys, verify suitability with trial cuts or consult application specialists before production use.
