Carbide Drill Bits
Tungsten carbide drill bits for drilling hardened steel, cast iron, and stainless steel. Superior wear resistance and precision from our Hangzhou manufacturing facility.
Carbide Drill Bit Selection
Match Carbide Drill Bits to Rigidity, Workpiece Hardness and Tool Life
Carbide drill bits are not simply “stronger HSS”. They need the right machine rigidity and application. Use them when tool life, precision and abrasive wear matter more than the lowest unit price.
| Buyer scenario | Recommended specification | Best-fit use | Quotation focus |
|---|---|---|---|
| Solid carbide precision drilling | Ultra-fine grain carbide, CNC ground | CNC machining, precision holes | Runout control, repeatability, cost per hole |
| Carbide for abrasive workpieces | Wear-resistant carbide grade, coating optional | Cast iron, high-silicon aluminum, composites | Longer life than HSS, controlled chipping risk |
| Carbide-tipped option | Carbide tip brazed to steel body | Larger diameter or masonry/industrial holes | Lower cost than full carbide, good impact resistance |
What to send before quotation
Send workpiece hardness, machine type, hole tolerance, depth, coolant condition and monthly usage.
Send Specs to WrynoAbout Carbide Drill Bits
Wryno Global is a professional carbide drill bit manufacturer producing tungsten carbide drill bits for the most demanding industrial drilling applications. Our solid carbide and carbide-tipped drill bits are engineered to maintain cutting edge integrity at high temperatures, making them the preferred choice for drilling hardened steel, cast iron, stainless steel, and other tough alloys.
Unlike HSS drill bits, tungsten carbide drill bits deliver significantly longer tool life and maintain dimensional accuracy over extended production runs. Our carbide drill bits are manufactured using ultra-fine grain tungsten carbide blanks (submicron grade), precision-ground on CNC tool grinders to ensure consistent geometry and cutting performance across every piece in the batch.
As a direct carbide drill bit supplier, we offer both standard sizes and custom OEM specifications. Whether your application requires solid carbide drill bits for precision engineering, or carbide-tipped masonry drill bits for construction, we can produce to your exact requirements with competitive factory pricing and reliable lead times.
Applications & Materials
Hardened Steel
Carbide drill bits excel at drilling hardened steel above HRC 45. Superior heat resistance maintains edge integrity where HSS bits fail.
Cast Iron
Tungsten carbide drill bits deliver clean, precise holes in cast iron components. Minimal wear ensures consistent results in production environments.
Stainless Steel
Solid carbide drill bits handle stainless steel drilling with precision. The rigid carbide body reduces deflection and ensures accurate hole placement.
High-Temp Alloys
Carbide drill bits are essential for drilling nickel alloys, titanium, and other high-temperature metals in aerospace and energy applications.
