21mm T-Slot Cutter HSS-Co Cross-Tooth 8 Teeth, Right-Hand - ALPEN-MAYKESTAG GmbH

The combination of durable HSS‑Co construction, precise 21 mm nominal diameter and a 12 mm shank with drive flat ensures reliable T‑slot milling with consistent chip control; order the cutter directly via Metav Werkzeuge or consult the technical team for application advice.

T‑slot cutter DIN 851 AB Type N D.21 mm HSS‑Co, 8 flutes by ALPEN‑MAYKESTAG

A robust T‑slot cutter designed for machining construction, case‑hardened and quenched‑and‑tempered steels and for short‑chipping non‑ferrous metals in industrial toolrooms and CNC shops.

• HSS‑Co for enhanced heat resistance
• Cross serration for improved chip control
• Shank Ø 12 mm with drive flat
• Right‑hand cutting for conventional milling

Controlled chip formation for safer, faster milling

The cross serration (Kreuzverzahnung) on the cutting edges produces short, manageable chips and reduces heat concentration at the cutting edge, which is particularly valuable when working with tougher alloys. Combined with the HSS‑Co substrate, this geometry extends tool life under interrupted cuts and higher metal removal rates. The tool’s 8 cutting edges enable evenly distributed cutting forces, which lowers vibration and contributes to a stable surface finish in slotting operations. These technical choices translate directly into improved cycle times and lower rework rates for production and maintenance tasks.

Secure clamping and precise dimensional control for CNC work

A 12 mm shank with drive flat provides a positive drive and repeatable concentricity in collets and shrink holders, minimising runout for fine slot tolerances. The cutter’s nominal diameter 21 mm and cutting length 8 mm are matched to DIN 851 AB Type N design, which supports consistent groove geometry for standardised T‑slots. With an overall length of 74 mm the tool permits safe tool engagement and clearance in common milling setups. These attributes make the cutter a dependable choice for toolrooms and small series production where reproducible results and machine uptime are priorities.

Efficiency, durability and workshop confidence

Right‑hand cutting orientation ensures predictable chip evacuation in standard machining strategies and suits both manual and CNC operations. The combination of HSS‑Co material and the serrated edge design requires less frequent regrinding in comparison to unalloyed high‑speed steels, yielding lower total tool costs over life‑cycle and fewer tool changes on the machine. For procurement and workshop managers, choosing a cutter with this specification offers a pragmatic balance of performance and service life, backed by the supply reliability and technical support provided by Metav Werkzeuge.

FAQ

What materials is this cutter suitable for?
The ALPEN‑MAYKESTAG T‑slot cutter is specified for machining construction, case‑hardened and quenched‑and‑tempered steels and for short‑chipping non‑ferrous metals, as indicated in the technical description.

How does the cross serration benefit milling performance?
Cross serration on the cutter breaks chips into shorter segments, which reduces heat at the cutting edge and improves chip evacuation; this enhances life of the HSS‑Co tool and contributes to consistent surface quality.

Is the shank compatible with standard collets and toolholders?
Yes, the 12 mm shank with drive flat provides secure engagement in standard collets and shrink holders, supporting repeatable concentricity and minimal runout during milling.

Which standard and type does the cutter conform to?
The tool conforms to DIN 851 AB, Type N, providing a standardised profile suitable for T‑slot production and workshop reuse.

What is the exact product identifier for ordering?
The SKU for ordering is 4117802038NW, listed under the ALPEN‑MAYKESTAG T‑slot cutter specification.
