ALPEN-MAYKESTAG Alpen HSS-Cobalt PCTM 5-Piece Drill Bit Set

The ALPEN-MAYKESTAG Alpen HSS-Cobalt PCTM 5-piece drill bit set is a professional-grade solution for precision drilling in tough materials. Manufactured from high-speed steel with cobalt alloy (HSS-Co), these bits offer exceptional heat resistance and durability, making them ideal for stainless steel, cast iron, and non-ferrous metals. The set includes five commonly used sizes (4.0, 5.0, 6.0, 8.0, and 10.0 mm) in a robust plastic case for convenient storage and transport.

Advantages

Each drill bit features a 135° split point for self-centering and reduced walking, ensuring accurate hole placement. The precision-ground cutting geometry delivers clean, burr-free holes, while the cobalt content enhances hardness and heat resistance for extended tool life. The cylindrical shank ensures compatibility with standard drill chucks.

Suitable for

• Drilling in stainless steel, alloy steel, and cast iron
