TOOL giant Hilti has developed a brace of products to increase productivity.
The firm has developed a screwdriving system for dryliners that is claimed to boost installation times while saving 25 per cent on costs.
The SD5000 uses a collated screw magazine that enables fast driving and one-handed operation.
Product manager Walid Hussain said: 'We are told drylining can often be a bottleneck in building. The alternative screw guns are labour intensive and harder to drive consistently, whereas our magazine allows driving at twice the rate of a conventional screwdriver and you don't drop your screws.'
The individual driving speed of 2.1 seconds a screw, according to Hilti, adds up to 50 per cent higher area installed, at around 276 sq m a day.
The labour gains are such that even with more expensive screws, cost savings should be around 25 per cent, Mr Hussain said.
At the same time, Hilti has boosted its biggest cordless drill to provide 50 per cent more holes per battery charge from a 40 per cent lighter pack.
The 36V TE6-A's lithium-ion battery can achieve a hundred 1,200 mm holes a charge, or a day's work, the firm said.
All battery replacements within the first two years are covered by the firm's 'no quibble, no cost' warranty.
