M35 HSS Cobalt Drill Bit, 2.5mm Diameter Twist Drill bits, Split Point for Drilling Metal Steel Aluminum 10Pcs

The M35 HSS Cobalt Drill Bit set, featuring 2.5mm diameter twist drill bits, has garnered a mix of feedback from users, showcasing both strengths and weaknesses in their performance. Customers recognize their capability to effectively drill through softer materials such as mild steel, plastic, and wood, approving the value for money offered by the set Considering its price point. Users highlighted that several bits have lasted approximately 300-400 holes, demonstrating decent durability within that range. However, when it comes to drilling more robust materials like stainless steel, users encountered challenges. Some drilled successfully after sharpening the bits manually, which indicates an element of maintenance advantage over coated alternatives—these bits can be resharpened easily. Conversely, several customers reported that the bits were not sufficiently strong for more demanding tasks, with some snapping when used on steel screws. Additionally, there were complaints regarding the pack containing one less bit than advertised, and concerns about the bits' usability in hand drills due to their small size. Overall, while the M35 HSS Cobalt Drill Bit set offers a reasonable solution for hobbyists and light-duty tasks, potential buyers should be prepared for limitations regarding heavy-duty performance and should have some sharpening knowledge to get the best out of these bits. **
