Where The Rubber Hits The Road

How Drill Bits Work


This week, Andy Abernethy, a Store Representative in our Liverpool Hilti Store explains how the choice of drill bit really can save crucial time…

‘How much for that drill bit?’ Is a question I’m asked on a regular basis working in the Liverpool Hilti store. My response however is not an answer many people have heard before. And it goes a little like this…

In the UK, there’s a popular car entertainment programme which surprisingly can assist us when it comes to our drill bit choice. In one episode the hosts attempt to convert a people carrier into a sports car and achieve a specific lap time. They try numerous modifications but the one thing that made one of the biggest differences for the smallest amount of money wasn’t: increasing the power, lightening the vehicle, or improving the downforce or suspension, but fitting better tyres. Basically, the point of contact with the road from the tyres was crucial and it’s the same with drill bits and all power tool inserts really.

You see, buying a good drill and using the cheapest drill bits you can find is like buying a racing car and fitting it with budget road car tyres - the power will be there, but you won’t be able to enjoy it to its fullest potential. Equally, just like putting good tyres on an average car, you can increase the performance of your tools just by using high quality inserts. For example, did you know our TE-CX drill bits enable you to drill up to 30 per cent more holes per charge with a cordless tool and you can complete those holes 80 per cent faster when compared to using standard bits? That’s a huge time and effort saving and we all know the most valuable thing on a job (and indeed in life in general), is your time.

Aside from the initial time and money saving, using high quality inserts will also prolong the life of your tools:

A) Because you’re not using them for as long

B) Because you’re less likely to push the tools too hard to get the job done

This also has a knock-on effect to your health as you can decrease your exposure to potentially damaging hand arm vibration levels and excessive dust production – a ‘win-win’ situation!

At this point in my answer most people begin to understand the cost jump from standard to premium inserts, but some still doubt that the initial extra outlay is ever fully recovered in the lifetime of the insert. However, research has shown that our premium inserts not only fully recover the initial expense but achieve 30 to 50 per cent lower lifetime costs on average when compared to standard inserts.

Now, something which makes everyone’s day better. Our premium inserts can become up to 50 per cent cheaper (and sometimes more) when you buy them in multipacks or sets compared to the cost of a single bit. A great example of this is one of the premium drill bit sets I sell more than any other in the Liverpool store, it contains some of the most useful sizes (1 x 5mm, 2 x 6mm, 1 x 8mm, 1 x 10mm and 1 x 12mm) and costs just £19.99 plus VAT. To buy these drill bits as singles could cost as much as £71.50 plus VAT – that’s a 72 per cent saving!

The good news is, this story not only rings true for drill bits but for our other premium inserts too, as the benefits are mirrored across saw blades, grinding discs, chisels and many more.

So, the question I always ask is: will you invest where the rubber hits the tarmac, or do you want to dilute the performance of your sports car and spend more than you have to with inferior inserts? Seems like a no-brainer to me but, let us know on social media!
