10PCS R2.5 Centre Drill, HSS 60-Degree Angle Centre Drill bit, Suitable for Lathe Metalworking Countersink Drill Tools DRINYOUNG (Type R, R2.5 10pcs)

Características 【Product Details】 Material: HSS Model: Type R Diameter: 2.5mm / 0.1in Shank Diameter: 6mm / 0.24in Overall Length: 45mm / 1.77in Quantity: 10pcs Note: All measurements below are taken manually and may contain discrepancies.Please refer to the actual product for accuracy. 【Arc-shaped cutting edge for improved impact tolerance】 The arc design without transverse edges prevents stress concentration, enabling morerational distribution of stress. When machining high-hardness or non-uniform materials, it effectively reduces chipping during initial engagement. 【Single-pass formation of smooth hole edges and chamfers】 While centring and drilling, it naturally produces a relatively smooth arc-shaped chamfer, helping to minimise burrs at the hole edge, enhance appearance, and offer reliable guidance. 【Outstanding material adaptability and versatility】 Delivers consistent performance withcommon materials from mild carbonsteel to stainless steel. Its robust constructionremains reliable when processing diverse material varieties. 【Well-balanced for steady performance】 Symmetrical geometry reduces vibration during high-speed rotation, supporting modern machine tool capabilities to ensure positional accuracy of holes. 【High alignment tolerance and simplified use】 It shows increased tolerance for minor surface imperfections or initial alignment inaccuracies in workpieces, lowering requirements for positioning precision and improving ease ofoperation.
