Minibohrnutenfräser D.5mm HSS-Co8 Weldon Z.3 kurz TECWERK — mini slot cutter, 3-flute, HSS-Co8

Minibohrnutenfräser D.5mm HSS-Co8 Weldon Z.3 kurz TECWERK is a compact slot milling cutter designed for precise miniature slotting and plunge operations in confined setups, especially where high-strength HSS-Co8 wear resistance is required.

• HSS-Co8 high-cobalt construction
• Centre-cutting for plunge milling
• Weldon shank with drive flat
• Very good for steel and cast iron

Precision for miniature slotting and plunge work

The short, three-flute design delivers a balance between rigidity and chip evacuation that is essential for small-diameter slotting. Machined from HSS-Co8, the tool offers higher hot hardness and abrasion resistance than standard HSS, which translates into longer tool life in intermittent cutting and when encountering harder feeds. The centre cutting geometry permits controlled plunging into the workpiece, enabling accurate pocket starts and short axial entries without pre-drilling. This results in fewer setup steps and more predictable machining cycles for small, high-precision components.

Secure clamping and consistent performance in common materials

A Weldon shank with drive flat and a 6 mm shank diameter ensure a reliable mechanical grip in standard collets and holders, reducing slippage and runout in compact milling spindles. The cutter is specified for materials up to ≤ 800 N/mm², with very good suitability for steel and cast iron and conditional suitability for non-ferrous metals and stainless steel. For production environments where stability and repeatability matter, the combination of robust shank fixation and the cutter’s geometry yields consistent slot widths and improved dimensional control compared with generic miniature cutters.

Compact design for tight spaces with good surface finish

The short version is intended for operations where reach and overhang must be minimised. The right-hand cutting orientation and the balanced flute geometry reduce chatter and promote an excellent surface finish in slot walls and bottom faces. In application, this cutter is well suited to small jig milling, toolroom adjustments and repair tasks where access is limited and precision is required. Select cutting parameters conservatively for hardened or highly alloyed steels; the HSS-Co8 base material helps maintain edge integrity under higher thermal loads typical of interrupted cuts.

FAQ

Can this cutter perform plunge cuts without pre-drilling?
Yes. The centre-cutting geometry allows controlled plunge milling; the three-flute layout supports chip removal during axial entry.

Which materials are best processed with this cutter?
The cutter is optimised for steel and cast iron with very good suitability; non-ferrous metals and stainless steel are conditionally suitable up to the specified strength.

How does the Weldon shank improve machining reliability?
A Weldon shank with a drive flat provides positive mechanical engagement in the holder, reducing slippage and runout for more repeatable slot widths.

Is the tool suitable for compact milling machines and small spindles?
Yes. The short design and 6 mm shank make it appropriate for machines with limited tool overhang and smaller collet systems.

How does the HSS-Co8 composition affect tool life?
HSS-Co8 offers increased hot hardness and wear resistance compared with standard HSS, which supports longer life in demanding or interrupted cutting tasks.
