Produktbeschreibung

1.High-Speed Steel for Hardness & Durability：This countersink is crafted from high-speed steel, which delivers strong hardness to handle repeated drilling tasks without dulling easily; it also ensures long durability, maintaining performance even with frequent use on low-hardness materials. 2.5-Piece Set for Diverse Demands：The set includes 5 countersink drills with different diameters and shank shapes—each tailored to meet various drilling needs, from small holes to larger chamfers, eliminating the need to buy separate tools for different tasks. 3.Five-Flute Design for Smooth Chip Removal：Featuring a five-flute design, it removes wood sawdust and debris more rapidly and smoothly during drilling; this prevents clogging, keeps the drill bit clean, and ensures neat, precise holes every time. 4.Multifunctional for Drilling & Finishing：It’s great for multiple tasks—drilling initial holes, chamfering (smoothing hole edges), deburring (removing sharp burrs), and countersinking (creating recesses for screws); this versatility makes it a go-to tool for DIY and small projects. 5.Suitable for Low-Hardness Materials：Ideal for drilling holes on low-hardness boards like thin aluminium sheets, wood boards, PVC boards, and insulating plates; note it cannot be used for glass, iron plates, or steel plates to avoid damaging the tool or material.
