A heavy duty professional curved pole saw with a blade length of 330mm. The blade has 7.5 teeth per 30mm and is suitable for cutting large branches.ï¿½ï¿½The blades are made from SK-4 high carbon steel and taper ground i.e. thicker at the tooth edge, thinner at the back of the blade. This taper reduces resistance giving smoother , easier, faster cutting performance. The hard chrome plating finish produces an exceedingly hard, durable surface. The blade is resistant to rust and the effects of tree resin and will wipe clean easily.ï¿½ï¿½This lightweight extension pole saw is available in 3 adjustable lengths from 1750 mm to 3850 mm when fully extended. The oval shape of the poles makes them strong and rigid and the rubber covered base section provides excellent grip. Each telescopic section is locked with a clever flip grip that can be operated with one finger.
