A quick look at multi-purpose drill bits and why you may need one.

What is a multi-purpose drill bit?

Multi-purpose drill bits are do it all drill bits. These are also referred to as multi-material and multi-construction drill bits, and will far outperform any HSS rolled general purpose drill bit. If you find yourself up against almost any material, including wood, metal, plastic or masonry, then the multi-purpose drill bits act as get out of jail cards, providing you a simple and effective way of getting through the required material. These multi-material drill bits are must have accessories for any professional tradesmen or DIY enthusiast.


Are multi-purpose drill bits any good?

Multi-purpose drill bits are extremely reliable and practical for drilling through a variety of different materials. The drill bits can help you get through a variety of materials including wood, masonry, tiles, aluminum, cast iron, steel, corian and plastics.

They are a fantastic power tool accessory to have in any toolbox. These drill bits are usually manufactured from steel, with a piece of tungsten carbide on the tip of the multi-construction drill bit. This provides a quality and robust multi-purpose bit which will drill itself through all materials. The tungsten carbide on the tip is an extremely hard material that is made by reaction of tungsten and carbon at extreme temperatures. This material rivals the hardest known material; diamond, and provides any user with a long-lasting accessory, to drill though a variety of different materials.

The performance of any multi-material drill bit will depend on its quality and where it has come from, you can find out more about DART’s great quality and durable multi-purpose drill bits below.


Can a multi-purpose drill bit replace my other drill bits?

Before the invention of the multi-purpose drill bit, many professional tradesmen had to rely on a variety of different bits in order to drill through the required material. For example, people had to have specific drill bits for wood, tile, masonry and metal etc, thus resulting in a very full toolbox of different drill bits. The introduction of the multi-construction drill bit is a great benefit for any professional tradesmen, providing them with the option of only needing one drill bit, to get through all materials. Tradesmen no longer have to worry about having the correct drill bit for the job; they can rely on the multi-purpose drill bit to drill any hole to a high standard.

In most situations, the multi-material drill bit can replace the work of any drill bit in your toolbox, however there are some situations in which it is better to use a material specific drill bit. For example, if you are a joiner needing to make very precise holes in wood, then a wood specific drill bit such as a DART’s brad point drill bit, will usually perform better than a multi-purpose drill bit due to its very sharp tip that creates tear free holes.

Another example could be, in an industrial or factory setting, where you may be drilling hundreds of holes in a hard material such as stainless steel, then it would be more cost effective and better to use a twist drill, such as DART’s M2 TiN     coated twist drills, due to their extreme resistance to heat and wear.

If you are a kitchen fitter, electrician, plumber, or general builder, then the multi-purpose drill bit will be the perfect drill bit for you. They help you to get the job done effectively and quickly, whilst preventing you from having to carry around a variety of different drill bits. You will only need to rely on the multi-purpose drill bit.




Does it matter what brand of multi-purpose drill bit I put in my drill?

NO, it doesn’t matter what brand of multi-purpose drill bit you use. Most will come with a quick-change hex or a round shank. Both these shank types will fit in all brands of power drills, not including drills specific for SDS+ or SDS Max drill bits. However, the longevity and quality of cut you get from your multi-construction drill bit will depend on the brand.


A deep dive into DART's multi-purpose drill bits.

DART’s multi-purpose drill bits are robust and reliable, they are long life bits that give outstanding performance.

Universal drill bit - The DART range of multi-purpose drill bits will fit onto any drill, such as a DeWalt, Bosch or Makita combi drills.

Wide size range - DART has a very large range of multi-purpose drill bits ranging in sizes from 4.0mm to 12.0mm, with overall lengths between 50mm and 250mm, and working lengths varying between 40mm and 165mm. The most common drill bit sizes are 6.0mm and 7.0mm, this is because they often get used for drilling holes for red and brown plugs.

Hex and round shank - They also come with the option of having a round or hex shank, allowing you to fit our drill bits onto whatever drill you may have. DART’s multi-material drill bit set comes with hex shanks, as this type of shank allows for a very quick drill bit change over.

Tungsten carbide tip - The 120° diamond ground, carbide tip helps give the drill bit a very long life and even faster drilling in hard materials. The 120° angle is the ultimate angle for drilling through all materials. Having a steeper angle is better for cutting through soft materials such as wood, and shallower angles are more suited to harder materials such as concrete. Having the 120° is perfect for being able to drill through all materials, hard or soft.

Optimum waste removal - The steep, aggressive u-type flute give optimal waste removal, this is very important to prevent the drill bit from jamming, due to waste getting stuck inside the hole. Without the fast waste removal, the drill bit would heat up, causing extreme friction when drilling, which would affect the durability and life of the multi-material drill bit.

Multi-material - DART’s multi-construction drill bits are suitable for use in materials including wood, masonry, tiles, aluminium, cast iron, steel, carbon and hard and soft plastics.
