OSG Tap & Die has added 8D sizes to its Hy-Pro-Carb drill series, which also includes 3D and 5D sizes. Suited for a variety of materials, the entire series’ point and flute geometry is designed to reduce thrust forces and chip size. Higher feeds and metal removal rates may be achieved with the addition of coolant-through capabilities, the company says. 3D and 5D sizes are available in both solid and coolant-through models, and 8D in coolant-through only.

The drill series’ applied multi-layered TiAlN coating is said to resist thermo-cracking from heat, thus improving wear resistance over conventional coatings. According to OSG, the common DIN shank sizes not only improve rigidity, but also reduce the number of toolholders needed to accommodate them.
