Westward 6PRY1 Metal Drill Bit, 4 mm Drill Bit Size, 43mm Flute Length, 75mm Overall Length

These drill bits have been engineered for durability, owing to a unique TiN coating that shields them from both wear and high temperatures. As a result, they are exceptionally well-suited for handling challenging metals like steel, stainless steel, and aluminum. The inventive parabolic flutes boast a broader and deeper design, effectively eliminating chips and maintaining the bit's coolness. Consequently, this leads to quicker drilling speeds and neater holes, even during extensive cutting operations.
