Cutting edge diamond drilling performance 26 January 2018

Hilti Group has improved its SP and SPX core bit ranges with the use of Hilti Equidist (EQD) technology, which delivers increased drilling speeds of up to 50% when compared with its predecessor core bits.

During the manufacturing process high-quality, industrial grade diamonds are precisely placed at an equal distance and in the best possible formation to deliver even higher drilling speeds and durability. Hilti Equidist (EQD) ensures all the diamonds in the cutting edge are in constant contact with the base material to maximise productivity throughout its lifetime.

In recognition of the fact that different materials require different diamond segment specifications, the company has also began colour coding its core bits for easy recognition. Those marked with a grey dot are for use on concrete, green for abrasive concrete and orange for masonry.

The new range also works with the innovative Hilti X-Change Module (X-CM), which enables users to quickly and easily retip core bits on the jobsite. Core bits traditionally come as one single unit, which means that when the diamond segment wears down, the entire unit had to be sent for retipping. The X-CM features a removable ring on the barrel, which can be quickly and easily removed with a screwdriver before a new one is pushed, twisted and clicked into place.

With standard core bits there can also be challenges if the core bit gets stuck in the hole or base material lodged in the barrel, which increases downtime and can result in a damaged unit. With the Hilti X-CM the system’s geometric design means users can simply remove the ring and slide the core out, providing a quick and simple solution for previously costly and time-consuming situations.
