Wax paper 10 sheets 1/3rd A4 size (approximately 70mm x 297mm). Very easy to use simply place on top of the stack it lubricates both inside and outside of drill bit and helps to ensure trouble free drilling. Each sheet can be used many times until it is exhausted. Far more effective than using candle wax. Please do NOT use candle wax as this can cause blockages when it cools down, plus it ends up all over the drill and your clothes.
