Step drills - burr-free drilling in sheet metal

With a BAER step drill, it is possible to combine several machining steps in one operation to efficiently produce holes with several different diameters. These tools provide clean surfaces and precise alignments when stepped holes are required and are usually suitable for materials up to 4 mm thick. We stock a wide range of different top quality drills in the shop, which can even be used for materials up to 6 mm thick.

Step drills for stainless steel and other materials - especially important for working with cable bushings

At BAER Tools you will find step drills for various materials. Both our HSS (High Speed Steel drills) and our HSS-TiAlN drills are perfectly suited for materials such as structural steels, CrNi steels and non-ferrous metals and stainless steels up to 6 mm thickness.

Especially in the electronics sector, our HSS step drills for cable glands according to DIN EN are in great demand. With them you can make steps for core holes as well as steps for through holes very precisely and exactly. This is necessary, for example, according to the DIN standard mentioned, when setting up or processing house connection, terminal or cable junction boxes as well as switch cabinets, various housings, installation boxes or switch and control devices.

In this application, it is important to safely insert or remove the various sealed cables and hoses in sheet metal or plastic housings. With the right step drill, you can easily make the required holes with the exact diameters in one step. The lasered markings on the steps of the drill make it very easy to ensure the dimensions.

Further advantages of the step drills for cable glands:

• Cutting angle in the entire course of the spiral groove
• High and uniform cutting performance
• Smooth running
• Optimum chip transport
• Longer tool life time
• Three-surface drive shank prevents slipping in the drill chuck

Our BAER Tool assortment for step drills

We offer step drills with different numbers of steps, step dimensions and step heights, as well as different shanks. You will find all the relevant information about them briefly and clearly in the respective product description. The drill material is also indicated here.

An example: our HSS-TiAlN step drill 10 - 45 mm with 8 steps:

• Material: HSS + TiAlN - Titanium Aluminium Nitride coated
• Steps: 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm
• Step height (or possible material height): 4mm

Our high-quality and stable step drills are ideal for burr-free drilling of sheet metal, profiles or pipes. As the step drills, in contrast to the peeling drills, produce cylindrical holes, you always use the next drill step for deburring the drilled hole. Thanks to the deburring zone, which is also present, you can also use this drill very conveniently for the rear cutting edge deburring (edge breaker). Our drills enable deburring up to 1.5 mm material thickness!

Further advantages of our step drills:

• High and even cutting performance
• Longer tool life time
• Smooth running
• Optimal chip transport
• Robust and durable design

Properties and application of the step drill

If you do not have any previous experience with a step drill, we will be happy to explain its use to you in a personal conversation and also help you choose the right drill for your application.

These drills are much more effective than other common twist drill bits due to their excellent precision and high working speed. The design of these step drills is conical and consists of different steps, which mean different diameter steps. This makes it possible to drill different holes from both thin and thick materials. In addition, however, you can also use them to re-mill and enlarge existing holes.

The step drills are self-centering and can therefore also be used on slippery or rounded surfaces. On the one hand, this eliminates the need for pre-drilling and on the other hand, you can also use the drill excellently for drilling pipes. You can use it to machine various materials such as thin non-ferrous metals, but also sheet steel or plastic as well as stainless steel.

When using it, please note that the height of the lower blade of the drill is decisive for the suitable material thickness. The side blades are used to drill the through holes. The point angle between the two cutting edges is also important. A large angle ensures greater contact pressure and better centring in the material.

The highest quality step drills are made of high-speed steel with a titanium coating for improved resistance. And of course you will find these in our range!

There are important differences.

If you want to drill through thicker material, each step needs to be longer so it will exit the back side before the next step engages the front side of the material. However, long step bits are usually more of a hassle when working in tighter areas, so that's why most step drill bits don't have long steps.

If a step drill goes too large at the top end, the bit itself often will not fit down into the area where you want to drill a smaller hole.

If you want to drill thin sheet metal, you are better off with a step drill that has straight cutting edges instead of cutting edges that curve or slowly spiral around the bit. Straight cutting edges help the bit to better cut through thin material without the bit wanting to grab at or self-feed into the material.

If you want to be able to make custom sized holes in thin material, buy a step drill that's cone shaped or stepless. If you don't need to make custom sized holes, skip the cone shaped bits, because they are harder to stop at the right spot consistently if you are wanting to drill multiple holes of equal diameter.

If you want to enlarge existing holes in areas that have obstructions close behind, use a step bit that has a correctly sized large blunt cut end. Those can be expensive though, so that's why it is nice to have a couple cheap step bits on hand. If you use a cutoff wheel to remove the end of a cheap step bit for a custom one-time job, you will only be out a couple dollars instead of $20+.

I have probably 20 or so step bits. Cheap ones like the ones from HF as well as high quality brands. The cheap ones are more likely to go dull on the cutting edge, the expensive bits will stay sharp longer but will often eventually chip at the cutting edge. I prefer bits that go dull instead of chipping, so my selection leans a bit more towards the cheaper bits. I can resharpen a dull straight cut step bit a couple times pretty easily by using a Dremel or Foredom tool. You often have to grind away a lot of material to remove a chipped cutting edge, so a badly chipped higher quality bit is often not fixable. You have to either lean the bit side to side (while cutting by hand) to get it to cut through the chipped area or you throw it away.

Most people would be best served by picking up a couple cheap step bits (that still have good online reviews) in different sizes for general use. Buy better quality bits for any styles that you find yourself using most if you feel the need later on.
