BETA upotuspora DIN 335-C 90° 30 mm TiN HSS

This BETA countersink is a high-quality tool designed for precise deburring, chamfering, and countersinking operations. Manufactured to DIN 335-C standard, it features a 90° cutting angle and a 30 mm nominal diameter, making it ideal for creating clean, conical recesses for flat-head screws. The tool is made from high-speed steel (HSS) with a titanium nitride (TiN) coating, providing excellent wear resistance and extended tool life. Suitable for use on steel, cast iron, non-ferrous metals, and plastics, this countersink delivers consistent performance in both manual and machine applications.

Advantages

High-speed steel construction ensures durability and sharpness retention. The TiN coating reduces friction and heat buildup, allowing for faster cutting speeds and improved surface finish. The 3-flute straight flute design provides smooth, chatter-free operation, while the right-hand cut direction is standard for most drilling applications. The ground manufacturing process ensures tight tolerances (h8) for precise, repeatable results.

Suitable for

• Deburring sharp edges on metal and plastic parts
• Chamfering holes for easier assembly
• Countersinking for flat-head screws in wood, metal, and plastic
• Use in drill presses, CNC machines, or handheld drills
