Review on 🔩 Irwin Industrial Tools Unibit 10234CB by David Bar

Anyone familiar with the Irwin name knows that they are a manufacturer of quality machine tools. Be warned, like many companies, some Irwin products are manufactured overseas. When this nozzle arrived I immediately started using it. I used to use a set of old Harbor Freight step bits when they were producing quite an industrial product. These bits lasted for years before the TiNi coating wore off. I've recently switched to harder steels and have had to use cobalt drills for a few production runs. from butter. I would buy one of these beats in a different form at any time. I can assume that this racquet will last a few more years. I just wish the bit was double knurled for better chip evacuation but no complaints so far.
