Bohrnutenfräser DIN 844 Type W, 6 mm, HSS-Co8 — TECWERK short slot drill with Weldon shank

A Bohrnutenfräser DIN 844 Type W by TECWERK designed as a short, three-flute, centre-cut slotting cutter for precise milling of long‑chipping aluminium and other non‑ferrous metals, with a 6 mm Weldon shank for secure clamping.

• HSS-Co8 high-speed steel construction
• 3-flute centre-cut geometry
• Weldon shank, 6 mm diameter
• 40° helix for smooth chip evacuation

Consistent slotting performance with reduced chatter

The short, three‑cutting‑edge geometry delivers a balance between rigidity and cutting action. Built from HSS‑Co8, the cutter keeps a sharp edge under thermal load, while the 40° helix promotes effective chip removal when machining long‑stringy materials such as aluminium. This results in reliable slot quality and reduced tendency to build up material on the cutting edges, which is especially beneficial when working with soft, ductile non‑ferrous alloys.

Secure clamping for repeatable results

A Weldon shank with drive flat provides positive torque transmission in standard tool holders, reducing slippage in interrupted cuts and plunge operations. The 6 mm shank diameter matches common collets and Weldon holders, enabling quick tool changes and consistent concentricity. The centre‑cut design allows limited axial plunging for controlled entry, so threaded features and through slots can be started precisely without pre‑drilling.

Material suitability and application benefits

Designed according to DIN 844 Type W and optimised for non‑ferrous metals, this cutter excels in tasks that demand clean slot walls and accurate widths. The short version improves stiffness in compact setups and is therefore well suited to fixtures or small mill spindles. For jobs requiring high surface quality, the three‑flute layout reduces radial forces compared with two‑flute variants, producing smoother slot sides and less vibration.

Practical handling and production advice

The cutter’s profile features a relief ground length of approximately 5.5 mm, which limits contact length and reduces heat build‑up in shallow slots. For best results, employ moderate feed per tooth and appropriate coolant or air blast to aid chip evacuation when cutting long‑chipping aluminium alloys. The combination of HSS‑Co8 metallurgy and the specified geometry provides a cost‑efficient option where carbide is unnecessary or where machine rigidity favours a tougher, more forgiving tool steel.

FAQ

Is this cutter suitable for plunging into material?
The TECWERK Bohrnutenfräser DIN 844 Type W features a centre‑cut geometry that permits limited axial plunging; it is intended for controlled entries rather than heavy plunge‑roughing.

Which materials are recommended for this tool?
This slot drill is optimised for long‑chipping aluminium and other non‑ferrous metals; the HSS‑Co8 composition offers durability and edge retention in these applications.

Will the Weldon shank fit standard holders?
Yes — the 6 mm Weldon shank is compatible with standard Weldon holders and collets that accept a 6 mm diameter with a drive flat for secure clamping.

How does the 40° helix affect cutting?
The 40° helix improves chip evacuation and reduces packing when machining ductile materials, supporting smoother surface finish and consistent metal removal in slotting operations.
