The Dual Kit: 

Our 4 bit Willow Kit keeping 'Lefties' in mind! This kits is suitable for left and right handed use.

If you are left handed you must use bits created for left handed use. This is because the flutes of the teeth are manufactured in the correct rotation.

Left handed bits should still be used in Reverse motion.

All pieces are specially coated. This speciality layer has a two tone purple & bronze appearance which protects the bits from oxidisation, meaning they last twice as long as regular E-file Bits.

The kit is made up of 4 pieces: 

"The 5 in 1" Bit - Extra Coarse

The kit consists our best pieces for "Lefties" aiding you to make your job more effective, cost efficient and kinder on your body as well as your pocket. 

The bits must be cleaned periodically to remain sharp, by following the manufacturer's instructions. E-file bits usually last 2-3 months but this can vary dependent on how busy you are. However, the specially coated pieces within this range will last twice as long as the recommended replacement time. 


  • Pop your pieces in for a cleaning cycle in your Willow Ultra Cleanse
  • Use warm soapy water, our Spit-Spot-Bit-Pot and our Willow Brass Brush to remove the dust and product debris from within the grits, flutes and teeth. 

  • Do not allow the bit to air dry!

  • Once the bit is fully clean and dry you can use your preferred sterilising method. 

  • We recommend our "Willow Spray & Go" system as the less time your bits spend immersed in solution, the better!

  • Lay your E-file bits on a towel and evenly spray the Spray & Go over all of the bits.

  • Roll the bits over and spray evenly again.

  • If soaking in barbicide please only steep for the recommended time, over-steeping can dull your drill bits.

  • Wait 2 mins and then dry all of your bits thoroughly by hand (do not leave to  air dry)

  • Store in your bit case or bit book.

How do I know I need a new drill bit? 

If the bit you are using originally took 1-2 swipes along the nail to penetrate the product and now is taking 2,3+ swipes to penetrate the product, it's now time for a new bit. You may also be taking longer, or you may be starting to feel more body wear and tear, because you are having to work harder to penetrate the product. 

All drill bits are also available to purchase separately.
