Countersink Drill Bit Chamfering Set (3 Pieces)

Clean, Accurate Chamfers for Wood and Plastics

This 3-piece Countersink Drill Bit Oblique Chamfering Set is designed for precise deburring and chamfering on low-hardness materials such as wood, MDF, plywood, and thin plastics. Each bit is engineered to create neat, smooth edges around drilled holes, helping your projects look professional and reducing the need for additional finishing work.

Manufactured from robust steel with a corrosion-resistant finish, these bits are built for consistent performance in everyday workshop and DIY use. The cutting edges are shaped to reduce chatter and provide a cleaner cut, especially when used at moderate speeds. The set includes three commonly used sizes-6 mm x 46 mm, 9 mm x 49 mm, and 14 mm x 58 mm-covering a wide range of countersinking and chamfering tasks on screws, bolts, and through-holes.

For best results and extended tool life, use with moderate pressure and, where possible, cool with water or cutting fluid when working for longer periods. This compact set integrates easily into your existing drill and repair toolkit and is compatible with most standard power drills and drill presses.
