OSG Tap & Die’s Hy-Pro-Carb drill series now features 8D sizes. Designed for a range of materials, the drills’ point and flute geometry is said to reduce thrust forces and chip size. Higher feeds and metal removal rates may be achieved with the addition of coolant-through capabilities. The applied multi-layered TiAlN coating resists thermo-cracking from heat, improving wear resistance. Common DIN shank sizes improve rigidity and reduce the number of toolholders needed to accommodate them. The drill series includes 3D and 5D sizes in both solid and coolant-through models, and 8D size in coolant-through only.
