When it comes to drilling through stainless steel, speed and feed are critical considerations. As we’ve mentioned before, if your drill’s RPM is too high, the material will heat up and harden. When it comes to cutting steel, less is often more – with slower drilling speeds producing better results. It is, however, crucial that you maintain the surface footage per minute (SFM).

When you’re planning your next project, choosing the best fastener type is essential to the overall function of your final product. Coarse and fine thread screws are two specific fastener types that work well in various applications. The difference between fine and coarse thread screws can help you determine which one is right for your next project.

To drill through stainless steel, you need an HSS (High-Speed Steel) drill bit. HSS drill bits have sharp edges that can cut into the tough metal. To cut into hardened stainless steel, you will require a drill bit with a large point angle of at least 130 degrees.

Coarse threads allow more material to settle between the threading, making it harder for these screws to strip or cross thread. The threading can take on damage like nicks and marring and still function efficiently. Coarse threads are also less likely to gall or seize during tightening, making them easier to install.

Choosing the right fastener for your application is about understanding the environment, the material and how the screw will need to perform.

Feed rates can be high when drilling stainless steel. Not only will this increase the effectiveness of the tool, but it will also more effectively evacuate chips. It’s important to ensure that the feed rate is maintained and that you regularly check that heat isn’t building up in the material or the tool. If it is, then be sure to give it time to cool down.

Work hardening can cause stress to machinery and drill bits, shortening their life and increasing the chance of breakage.

At R.D. Barrett we stock a huge selection of drill bits for cutting through all materials, including stainless steel. You can view a selection of our tools online, or give us a call. We’re able to source drill bits and machine tools from a huge variety of manufacturers for all applications.

Fine threads are best for applications where vibration may be an issue. You’ll often find fine thread fasteners in machine parts, transmission parts and hydraulic systems because these applications involve high vibration. The materials best suited to fine thread screws include:

Stainless steel is robust, hard-wearing and corrosion resistant – which is why it’s such a popular material for manufacturers. You’ll find stainless steel used in almost every sector, including construction, automotive, transportation and consumer goods. The properties that make stainless steel so attractive also make it challenging to work with. Drilling through stainless steel requires the right machinery, the right tools and the right approach. In this guide, we describe how to drill stainless steel and stay safe.

Drilling into stainless steel requires precision tools for the perfect finish. At R.D. Barrett, we hold the UK’s largest selection of machine tools. If we don’t have it in stock, we can obtain it for you – at the best possible price. You can view a selection of machine tools on our website, or get in touch with us today. We’re always on hand to provide straightforward advice and guidance to help you select the right tool for the job.

Coarse thread fasteners have a wider thread pitch — the distance between each row of threading. Since this pitch is wider, coarse thread screws have a low number of threads across the distance of the fastener.

Drilling through stainless steel can be dangerous, so it’s critical to follow all safety procedures and processes. The biggest risk is hot chips of metal that can be thrown into the air. Wearing the correct personal protective equipment (PPE) will ensure you’re as protected as possible.

Steel has low thermal conductivity, which means heat doesn’t dissipate quickly. This can lead to heat building up on the cutting edge, which can cause damage and deterioration. The strength of the material makes it resistant to chipping, which can lead to a build-up of material around the edges of holes, lessening their strength. Stainless steel is also highly ductile, which means it stretches more than other metals, making it harder for the bit to remove chips.

Stainless steel isn’t the hardest metal around, but it is challenging to work with. The biggest issue is the risk of work hardening. If the cutting speed of the drill is too high and the feed is too slow, the heat generated can harden the material – making cutting more difficult.

In contrast, because of a narrow thread pitch, fine thread screws have a larger number of threads per distance. These threads offer higher tensile strength than coarse thread fasteners, and they’re often easier to tap. Since fine threading involves narrow, shallow ridges, there’s material to cut when forming threads.

The process of drilling can generate significant amounts of heat both on the drill bit and the material. Be careful when handling the drill bit or workpiece, particularly if you aren’t wearing gloves.

Stainless steel contains carbon, silicon and manganese within it. Some steels will also have elements of nickel and molybdenum added to increase corrosion resistance.

We recommend that you choose either a cobalt drill bit or carbide drill bit for stainless steel hole making. These high-quality and hard-wearing drill bits are able to stand up to the pressure of stainless steel, cutting through it with ease.

HSS drill bits are a different shape and made from different materials to those used to cut through wood or stone. There is a variety of HSS sharp drill bits with various designations. Here’s an explanation of what they mean:

When working with stainless steel, it’s advisable to drill in stages. This stop-start approach reduces the build-up of heat and allows both the tool and the material to cool down. Depending on the required hole diameter, you may drill in stages, using progressively larger drill bits until you achieve the desired result.

When drilling through stainless steel, avoiding the build-up of heat is essential, so ensure to lubricate and cool the drill bit regularly. As well as improving the cutting performance, this will increase the usable lifespan of the drill bit.

Stainless steel is an iron alloy that contains at least 10.5% chromium. The addition of chromium provides a protective layer of oxide on the surface of the metal, which prevents rust from forming and provides attractive heat resistant properties.

Generally, coarse thread screws work well in most applications. These fasteners offer the strength and ease needed for many construction and industrial applications. Coarse threads work well with the following materials:

Fine thread screws also have a shallow pitch or helical angle, making them more resistant to vibration. These fasteners also have less heft than their coarse counterparts, so they require less torque to install.
