TECWERK Slotting cutter DIN 844 Type W, Ø 18 mm — HSS‑Co8, Weldon, 3‑flute, short

TECWERK Slotting cutter DIN 844 Type W, Ø 18 mm — a short three‑flute centre‑cut tool engineered for efficient machining of long‑chipping aluminium and other non‑ferrous metals

• HSS‑Co8 high‑cobalt steel for enhanced wear resistance
• 18 mm cutting diameter, three flutes, centre‑cut
• Weldon shank with drive flat, 16 mm shank Ø
• 40° helix angle for efficient chip evacuation
• Optimised for long‑chipping aluminium and non‑ferrous metals

Precision and tool life for repetitive slotting operations

Manufactured in HSS‑Co8, this short slotting cutter is designed to offer a balance of toughness and wear resistance that supports sustained production cycles. The combination of a three‑flute geometry and an 18 mm cutting diameter reduces deflection in light to medium machining, improving dimensional stability during repetitive slotting or groove milling. The centre‑cut capability allows plunge entry where necessary, eliminating an extra drill operation and reducing cycle time in jigs and fixtures. Overall, this configuration aims to extend tool life while preserving surface quality on softer metals.

Faster machining through optimised chip control

A 40° helix promotes continuous chip flow away from the cutting edge, lowering the risk of built‑up edge when processing long‑chipping alloys. The steeper helix, paired with the 3‑flute layout, provides a compromise between cutting strength and evacuation capacity, which is particularly beneficial for aluminium alloys that produce long, stringy chips. The cutter’s geometry permits higher feed rates with stable chips, translating into more efficient material removal and fewer interruptions for chip clearing in batch production.

Practical mounting and workshop compatibility

The tool features a cylindrical shank with a Weldon drive flat and a 16 mm shank diameter, facilitating secure clamping and positive torque transfer in standard collets or chucks. A clear free‑cutting length of 15 mm supports deeper slotting without compromising rigidity. Designed under DIN 844 Type W, the short variant fits compact spindle setups and is suitable for both manual and CNC milling centres. Its right‑hand cut direction aligns with common spindle rotations, ensuring immediate integration into existing machining processes.

Where this cutter adds value in production

For workshops and subcontractors working with long‑chipping aluminium and other non‑ferrous metals, this short, centre‑cut slotting cutter reduces auxiliary steps and streamlines workflow. The material selection and flute geometry were chosen to cut heat generation and maintain edge integrity, which supports consistent tolerances and surface finishes across runs. In economic terms, the tool aims to improve uptime and reduce scrap by combining wear resistance with reliable chip control — advantages that matter across series production and repair tasks.

FAQ

What materials is this cutter best suited for?
The TECWERK slotting cutter (DIN 844 Type W, SKU 2000866290NW) is optimised for long‑chipping aluminium alloys and other non‑ferrous metals, offering excellent performance on these materials.

Can the cutter plunge into material or is pre‑drilling required?
Thanks to its centre‑cut design, the cutter allows plunge entries where suitable, so pre‑drilling may be omitted in many slotting operations with the TECWERK short cutter.

What is the shank size and how should it be clamped?
The tool has a 16 mm shank with a Weldon drive flat for secure clamping; use an appropriate collet or chuck to ensure positive torque transmission and minimise slippage.

How does the helix angle affect machining performance?
The 40° helix angle improves chip evacuation and reduces the tendency for long chips to clog, supporting higher feeds and more consistent surface quality during aluminium machining with this TECWERK cutter.

Is this cutter suitable for CNC milling centres as well as manual machines?
Yes, the short DIN 844 Type W variant is compatible with standard CNC milling centres and manual machines, especially where compact tool length and rigidity are priorities; the Weldon shank aids reliable mounting across setups.
