The Best Drill Bits For Stainless Steel
How We Found The Best Drill Bits For Stainless Steel?
Drilling through stainless steel can be a daunting task, especially if you don’t have the right tools. Stainless steel is a durable and hard material that requires specialized drill bits for clean and efficient drilling. We will explore the factors to consider and discuss the best drill bits available for stainless steel applications.
Understanding Stainless Steel
Before delving into the best drill bits, it’s essential to understand the nature of stainless steel. Stainless steel is an alloy of iron, carbon, and other elements, primarily chromium, which provides it with exceptional corrosion resistance and strength. Due to its hardness, drilling through stainless steel demands high-quality drill bits that can withstand the material’s toughness.
Factors to Consider
Material Composition: Stainless steel comes in various grades, each with different hardness levels. It’s crucial to know the specific grade you’re dealing with, as this information will help you choose the appropriate drill bit.
Drill Bit Material: High-speed steel (HSS) and cobalt drill bits are popular choices for drilling stainless steel. Cobalt bits, containing cobalt alloy, are more robust and dissipate heat better than standard HSS bits, making them ideal for stainless steel applications.
Coating: Look for drill bits with coatings like titanium nitride (TiN) or titanium carbonitride (TiCN). These coatings enhance durability, reduce friction, and increase heat resistance, making them suitable for drilling through tough materials like stainless steel.
Drill Bit Geometry: Split point or pilot point drill bits are preferred for stainless steel. These designs minimize bit walking and ensure accurate hole placement.
Size and Shank Type: Choose the appropriate bit size and shank type (round or hex) based on your drilling needs and the type of drill you’re using.
Best Drill Bits for Stainless Steel
Cobalt Drill Bits: Cobalt bits are specifically designed for drilling hard materials like stainless steel. They are resistant to heat and wear, making them durable and efficient.
Titanium-Coated Drill Bits: These bits have a titanium nitride or titanium carbonitride coating, providing excellent heat resistance and hardness. They are suitable for drilling through stainless steel due to their enhanced durability.
Carbide Drill Bits: Carbide bits are incredibly hard and are suitable for high-speed drilling in stainless steel. They maintain their sharpness for a long time and are ideal for precision drilling tasks.
HSS Drill Bits with Cobalt Additives: High-speed steel bits with added cobalt are an economical yet effective option. The cobalt content enhances their durability, making them suitable for drilling stainless steel at a lower cost than pure cobalt bits.
Choosing the best drill bits for stainless steel involves considering factors such as material composition, drill bit material, coating, geometry, size, and shank type. Cobalt drill bits, titanium-coated bits, and carbide bits are among the top choices for efficiently drilling through stainless steel. By understanding these factors and selecting the right drill bits, you can tackle your stainless steel drilling tasks with confidence, achieving precise and clean results every time.

FREQUENTLY ASKED QUESTIONS
What is the best way to drill stainless steel?
HSS or High-Speed-Steel bits are designed for use on stainless steel and can be used for hand and machine drilling. It is recommended to use an HSS bit that is TiN tipped as the Titanium Nitride reduces friction which in turn reduces work hardening caused by excessive heat and minimises flank and crater wear.
What is the angle of a drill bit for stainless steel?
For hard materials such as stainless steel, the point angle should be large and e.g. 130° or 135°. For soft materials, point angles of e.g. 118° are used. With a large point angle, more of the cutting edge engages in the workpiece when drilling.
What kind of drill bit do you use for metal?
The best drill bits for metal drilling in ascending order in terms of cost are High-Speed Steel (HSS) bits, Black Oxide bits, Cobalt steel bits, and Titanium bits. For drilling large holes in thin or soft metals, you can use a hole saw which can also be used with a cordless drill.
Can you flow drill stainless steel?
Flowdrill is available in many sizes, suitable for diameters from 1.8mm to 40mm and for material thickness from 0.5mm to 10mm. The area of application is steel, stainless steel, aluminium, copper and some brass alloys.
What is the hardest drill bit for stainless steel?
Carbide bits are the strongest drill bits material and can cut through hardened steel. But if they are not available, titanium and cobalt drill bits can also be used. However, drilling with either of these bits will take longer than drilling with a carbide drill bit.
What type of drill bit is best for stainless steel?
For drilling stainless steel, cobalt drill bits or high-speed steel (HSS) drill bits with a coating like titanium nitride (TiN) or cobalt are often recommended. These materials are known for their durability and heat resistance.
Can I use regular drill bits on stainless steel?
It’s not recommended to use regular drill bits on stainless steel as they may dull quickly and become ineffective. Specialized stainless steel drill bits are designed to handle the hardness and abrasiveness of stainless steel.
Are there specific drill bits for different grades of stainless steel?
Yes, some stainless steel grades are harder than others. For very hard stainless steel, it’s advisable to use cobalt or carbide drill bits, as they can maintain their sharpness and effectiveness when drilling through the toughest grades.
What size of drill bit should I use for stainless steel?
The drill bit size you need depends on the specific project and the hole diameter you require. Make sure to choose a bit that matches the size of the hole you want to create in the stainless steel.
How do I maximize the lifespan of my stainless steel drill bits?
To extend the life of your stainless steel drill bits, use cutting fluid or lubricant while drilling to reduce friction and heat. Drill at a lower speed, keep the bits cool, and avoid excessive pressure. Sharpen or replace your drill bits when they become dull to maintain their effectiveness.
