Husqvarna K770 VAC Petrol Disc Cutter

The Husqvarna K770 VAC has all the specifications and performance prowess of the flagship K770 machine with an additional dust extraction system. The 2" hose takes the dust away from the impact point and can be connected to an external dust extractor such as the Husqvarna S26.

Due to the repositioned guard and pulley, the K 770 VAC can cut to a maximum depth of up to 122mm with a 12" blade, which is almost as deep as you can get using a standard 14" machine. 

Husqvarna recommends the new Vari-Cut S35 Turbo blade, which has a softer bond suitable for lower RPMs. The spin speed of the K770 VAC is optimised for dust extraction, and the special laser-welded S35 blade is designed to achieve the best results in this scenario.

The latest disc cutter from Husqvarna, the K770 is now available with a dry dust extraction system. The new Husqvarna K770 VAC features an integrated gearbox, repositioned pulley and improved blade guard. This reconfiguration enables an increased cutting depth of up to 122mm.

Dust extraction on standard disc cutter models would traditionally require a water feed but the K770 Vac enables dry dust extraction. The retractable dust flap underneath the blade collects dust from the point of impact of the blade, and feeds it to your vacuum system via the hose.

You get all the features and benefits of the other Husqvarna K 770 models such as the EasyStart and DuraStarter technology, efficient fuel-to-power ratio, longer service intervals and much, much more.

Low vibrations in the handle mean that this power cutter can be used extensively compared to other machines without risking injury or discomfort.

K770 VAC is available for as little as £1025.00 + VAT if you already have a suitable blade, or for just £80.00 more (£1105.00 + VAT) you can get the saw package containing a 12" Husqvarna Vari-Cut S35 Turbo blade which itself has a RRP of £130.
