MAYKESTAG Slot Milling Cutter DIN 850 D — 28.5 mm HSS‑Co, 12 Teeth

A MAYKESTAG slot milling cutter designed for precise slotting and groove machining in construction, quenched and tempered steels and short‑chipping non‑ferrous metals

• Cobalt high‑speed steel HSS‑Co
• Complies with DIN 850 D
• 12 cutting edges for smooth material removal
• Cylindrical shank with drive flat

Consistent results from a cobalt HSS core

The cutter is made from HSS‑Co (cobalt‑alloyed high‑speed steel), which provides a balance between toughness and hot‑hardness compared with ordinary high‑speed steel. This material choice improves resistance to thermal softening during interrupted cuts, resulting in a longer effective tool life and more consistent machining performance when producing slots and grooves. The DIN 850 D designation ensures a defined geometry and manufacturing standard, which helps to predict cutting behaviour and makes the tool suitable for industrial production environments.

Efficient chip control and surface quality

With 12 teeth and a right‑hand cutting direction, the geometry supports steady chip formation and evacuation when machining short‑chipping materials such as brass, aluminium and certain non‑ferrous alloys. The cutter’s tooth count and geometry reduce vibration and promote a cleaner finish on the slot wall, delivering time savings through fewer finishing passes and predictable surface quality. For applications involving hardened or heat‑treated steels, the cutter’s design maintains cutting stability under moderate feed rates.

Secure clamping and machine compatibility

A 12 mm cylindrical shank with drive flat provides reliable clamping in standard collets and chucks, reducing the risk of slippage during higher torque operations. The tool’s overall length of 71 mm and cutting length of 12 mm permit use in common milling setups where moderate reach and rigidity are required. The combination of shank design and balanced geometry supports repeatable positioning and helps to reduce setup time on vertical milling machines and CNC centres.

Practical advantages for workshop operations

Specification conformity to DIN 850 D and the use of HSS‑Co mean the tool is straightforward to regrind and maintain, extending service life and lowering per‑slot costs in the long term. The tool is intended for slotting in construction and tempered steels as well as for machining short‑chipping non‑ferrous metals, which makes it a versatile choice for small series production and repair work. This predictability and maintainability support continuous workflow and reduce downtime in busy workshops.

FAQ

What materials is this slot milling cutter suitable for? The MAYKESTAG slot milling cutter is designed for machining construction steels, quenched and tempered steels and short‑chipping non‑ferrous metals as stated in the product specification (SKU 4117802240NW).

Can the cutter be regrinded after use? Yes, tools manufactured from HSS‑Co, such as this slot cutter, can generally be regrinded to restore the cutting edges, extending tool life with correct workshop practice.

Will the 12 mm shank fit standard collet systems? The 12 mm cylindrical shank with a drive flat provides compatibility with standard collets and clamping systems commonly used on milling machines and CNC centres.

Is the tool suitable for high‑speed machining? The cutter is made from HSS‑Co and is intended for robust slotting operations; for very high cutting speeds, application parameters and machine capability should be checked against material and process requirements.

Which standard defines the tool geometry? The cutter conforms to DIN 850 D, which standardises the tool type (N) and geometry to ensure predictable cutting behaviour.
