Makita HSS-TiAlN metal drill bits: drilling metal with an impact driver
Makita HSS-TiAlN metal drill bits have a 1/4" hex shank, so they fit a cordless drill and an impact driver. The best choice if you drill sheet metal, profiles or steel and want to change quickly between drilling and screwing: 25 sizes from 2.0 to 13.0 mm.
Makita HSS-TiAlN metal drill bits have a 1/4" hex shank, so you can use them in a cordless drill and in an impact driver. The tip has three cutting edges and centres itself, so the hole starts in the right place and the bit does not slide on the metal surface. There are 25 diameters from 2.0 to 13.0 mm, and each bit comes in its own pack.
What does HSS-TiAlN mean?
HSS (High Speed Steel) is the usual material for metal drill bits. TiAlN (titanium aluminium nitride) is the coating on the surface of the bit. Makita states that this coating gives the bit good heat and wear resistance, so it lasts longer, also in hard work.
The bit has wide and smooth flutes. They move the metal chips out of the hole, so drilling is faster and smoother.
Can you drill metal with an impact driver?
Yes, if the bit has a 1/4" hex shank. Makita impact drivers, for example the DTD173Z, have a 1/4" hex socket. The bit locks in with one movement, like a screwdriver bit. Makita marks these bits as suitable for drills and for impact drivers.
An impact driver is practical when a job needs drilling and screwing in turns, for example when you attach sheet metal or metal profiles. For a large, deep or precise hole, a cordless drill is better, because it has a clutch and turns smoothly. The keyless chuck of a drill also holds a 1/4" hex shank firmly.
These bits are not for concrete or stone. For that, see rotary hammers.
Sizes: 25 diameters from 2.0 to 13.0 mm
All bits have the same 1/4" hex shank. The larger the diameter, the longer the bit. Working length is the length of the spiral part of the bit.

How to drill metal so the bit lasts longer
- Clamp the part. Hold sheet metal, tube or profile with a clamp or a vice, so it does not turn with the bit.
- Mark the hole. The centring tip helps to start the hole in the right place. On a smooth and hard surface, a small centre-punch mark also helps.
- Choose the right speed. The larger the bit, the slower it must turn. With a small bit you can drill faster.
- Cool the bit. When you drill steel, use cutting oil or paste. The cutting edge then stays sharp longer.
- Do not push too hard. Even pressure is better than high force. If the chips turn blue or the bit smokes, the speed is too high.
- Drill a pilot hole for a large hole. A pilot hole made with a smaller bit makes the work of the large bit easier.

Frequently asked questions
Can you drill stainless steel with an HSS-TiAlN bit?
Makita marks these bits for metal and mild steel. Stainless steel is harder and gets hot faster, so drill slowly and cool with cutting oil. If you drill stainless steel often, ask the shop for a bit made for it.
Does a bit with a 1/4" hex shank fit a normal drill?
Yes. The keyless chuck of a cordless drill also holds a hex shank. Makita marks these bits as suitable for drills and for impact drivers.
Are these bits sold as a set?
This Makita series has 25 single bits, and each bit comes in its own pack. Choose the sizes you need one by one.
What is the difference between an HSS-TiAlN and an HSS-TiN bit?
Both are high speed steel bits; the difference is the coating. TiAlN is titanium aluminium nitride, TiN is titanium nitride. Makita states that the TiAlN coating gives the bit good heat and wear resistance.
