As a specialized carbide drill bit manufacturer, OPT Cutting Tools produces one of the industry's most comprehensive drilling ranges, spanning standard, coolant-through, and indexable designs engineered for steel, stainless steel, and hardened alloys. Every drill is manufactured under a single quality system that combines advanced grinding technology with rigorous inspection, ensuring that performance is consistent from the first hole to the thousandth.
Advanced Drilling Solutions
The 8D TiAlN-coated solid carbide drill achieves 120-180 m/min in steel with a tool life exceeding 3000 holes, making it a workhorse for high-volume production. For demanding deep-hole applications, the 15D coolant-through drill delivers extreme depth-to-diameter capability in hard metals, where chip evacuation and heat control are the limiting factors.
Indexable Drilling for Large Diameters
For large-diameter holes, solid carbide becomes expensive. The SP series indexable U-drill solves this with replaceable SPMG inserts, providing cost-effective performance across 2D, 3D, 4D, and 5D depths. This modular approach lets manufacturers replace only the cutting edges, dramatically lowering cost per hole on large bores.
Quality Assurance at Every Step
Manufacturing excellence is built into the process: five-axis CNC grinding produces precise flute and point geometries, in-house PVD coating applies consistent AlTiN, TiSiN, and other advanced coatings, and 100% Zoller inspection verifies critical dimensions on every drill before it ships. This uncompromising approach is why manufacturers in aerospace, automotive, and general engineering trust OPT Cutting Tools for their most demanding drilling operations.
