The HSS conical countersink is a professional tool designed for countersinking and deburring metal holes with high precision and a clean finish.

The hexagonal HSS conical countersink is made of ground high-speed steel (HSS), ensuring wear resistance and consistent performance even with repeated machining.

Structure and cutting technology

The HSS conical countersink is designed to deliver professional results thanks to:

• Three 90° cutting edges for uniform countersinking
• Absence of vibrations during machining
• Reduced burr formation
• Clean hole finish

Hexagonal shank and power transmission

The hexagonal shank allows for a stable connection with screwdrivers and power tools, ensuring:

• Increased torque transfer
• Precise countersinking flush with the material
• Safe use even with impact drivers
• Reduced slippage

Compatible materials

The HSS conical countersink is suitable for machining:

• Non-ferrous metal alloys
• Steel sheet
• Plastic materials
• Technical and industrial components

Standards and correct use

The countersink is manufactured according to DIN 335 and ensures optimal performance when used at low cutting speeds to prevent overheating and prolong its life.
