TJR® Countersink 90° Diameter 6.3-20.5 mm Made of HSS Steel with TiN Coating - Really Sharp - Countersink and Deburring Set for Wood, Metal and Plastic in Practical Storage Box

The TJR HSS 4241 Countersink Set is designed for durability and precision in high-temperature applications. Made from a high-quality steel alloy with tungsten, chromium, vanadium, and a higher concentration of cobalt than standard HSS, these countersinks offer exceptional hardness, wear resistance, and heat resistance up to 600°C. Ideal for both hand drilling and stationary drills, they maintain their sharpness and integrity even under intense conditions.

Thanks to a special industrial cut, these countersinks provide smooth cutting and fine finishes, particularly when working with materials like metal, steel, wood, plastic, and stainless steel. The set includes six of the most common sizes: 6.3mm, 8.3mm, 10.4mm, 12.4mm, 16.5mm, and 20.5mm, making it versatile for a wide range of tasks such as deburring and countersinking.

Each countersink is manufactured with a sturdy cylindrical shaft, providing additional stability when in use and ensuring compatibility with any standard drill chuck. For convenient storage and organization, the set comes with a practical storage box, keeping everything tidy and easily accessible.
