Mte HSS CO8 E DIN 844 BN End Mill Short 10 mm

Mte HSS CO8 E DIN 844 BN End Mill 10.0 mm

Short Series, 8% Cobalt Alloy, Straight Shank, High-Precision General-Purpose Solution

The Mte HSS CO8 E DIN 844 BN End Mill (10.0 mm) Short Series is a cutting tool designed for milling operations requiring high performance, precision, and wear resistance. This end mill is more resistant to high temperatures and challenging materials than standard HSS end mills. It is widely used for machining stainless steels (INOX), tool steels, cast irons, and general-purpose engineering steels. Its 10.0 mm diameter is ideal for medium-scale slotting, pocketing, and contour milling operations.

The product's core strength comes from its HSS-E (High-Speed Steel - Cobalt Alloy) material, containing 8% Cobalt. This alloy significantly increases hot hardness and wear resistance while maintaining the toughness of HSS, thus allowing for higher cutting speeds.

Technical Specifications and Material Details

The Mte HSS CO8 E End Mill features optimized characteristics for high-performance milling applications.

Feature Name	Detailed Description
Diameter (Nominal)	10.0 mm
Standard	DIN 844: German standard for cylindrical shank end mills.
Design Type	BN (Normal/Medium Fine Tooth): The tooth structure of the end mill offers a balance of medium precision and chip removal.
Series	Short Series: Provides higher rigidity (resistance to vibration) and stability. Preferred especially for shallow milling operations and short cutting depths.
Material Type	HSS CO8 (HSS-E 8% Cobalt): High-Speed Steel with 8% Cobalt added. Cobalt increases the material's hot hardness (Red Hardness), allowing it to work without degrading the tip at higher cutting speeds and in harder materials.
Shank Type	Straight/Cylindrical Shank: Compatible with the collets or hydraulic/mechanical chucks of most milling machines.
Cutting Direction	Right Hand Cut
Number of Flutes	Usually 3 or 4 flutes (Ideal for balance and chip evacuation).

Application Areas and Industries Used

This end mill is used in precision milling operations where high temperature and challenging material conditions are present:

Machinery Manufacturing and Mold Making: Fine machining and contour milling of high-strength steels, tool steels, and hardened materials.

Aerospace and Defense Industry: Machining of stainless steels (INOX) and light alloys thanks to its cobalt alloy.

General Metalworking: Slotting, pocketing, and edge milling operations on medium-sized parts.

Workshops and Educational Institutions: A versatile tool due to its applicability across a wide range of materials.

Medical Device Manufacturing: High-precision machining of stainless materials.

User Information and Benefits

This product appeals to users who want to perform long-lasting, high-performance, and precise milling in challenging and abrasive materials:

Ideal Balance of Material Removal and Precision: The 10 mm diameter offers both sufficient material removal volume and relatively fine detail machining precision.

High Temperature Resistance: Thanks to the 8% Cobalt alloy, cutting edges maintain their hardness even at high speeds. This extends the life of the end mill and allows for working with more aggressive parameters, especially in materials like stainless steel.

High Rigidity: The Short Series design significantly reduces the vibration and deflection of the end mill. This ensures better surface quality and longer tool life.

Performance in Challenging Materials: It exhibits superior performance in challenging materials such as stainless steels, alloy steels, and cast irons, where standard HSS end mills fall short.

Economical High Performance: It is more cost-effective than carbide end mills, and the superior hot hardness offered by HSS-E provides a sufficient and economical high-performance solution for many applications.
