Comparing with steel body, aluminum alloy body further lighten cutter head’s weight; The life span of spindle, bearing are longer and electronic consumption further reducing.
The Spiral Cutterheads are suitable for pre-planing having 3 main features, extremely High feeding speed, low noise and reducing tear out problem.
According to cutting material, LR-Tool offers two kinds of Spiral Cutterhead. One is Spiral Cutterhead for normal pre-planing, using 14 mm x 14 mm x 2.0 mm insert knife (30-degree bevel). The other is Spiral Cutterhead for heavy cutting, using 15 mm x 15 mm x 2.5 mm insert knife (37-degree bevel).
Spiral Cutterheads has a lot of advantage. To begin with LR-Tool’s special step grooves, it has astonishing chip-throwing ability to avoiding thrown chips hurt the workpiece’s surface. In addition, the noise level will drastically reduce by the step groove. Comparing with straight cutting angle, spiral cutting angle is a finer design. The cutting resistance will evenly distributed to many tiny square inserts that spirally arranged around the surface of cutterhead and continually cut the workpiece by each small point. This cutting way can remarkably reduce tear-out problem. Moreover, this lightly cutting method will diminish the load of bearing and spindle, extend the life span and reduce electric consumption. Moreover, upgrading to an aluminum body is also available. The Light-weighting body will lighten the load of bearing and spindle further .
The square insert knives are made by tungsten carbide, suitable for cutting solid wood and man-made material, MDF and plywood etc. Each square insert knife has four new edges and Each edge will surpass 10 times durable than High Speed Steel knife. If insert knife dulled, you don’t need sharpen it immediately, just clean and turn all knives 90-degree and you may keep on working. Until all 4 edges run out. On the other hand, the necessary replacing insert knife is not only blunt, but damaged by hidden rock or nail. If a square insert nicked, just spend a small price to replace the nicked insert. Comparing with replacing a set of expensive straight knife, this design is economical.
Large chips always weaken the efficiency of dust collection equipment. Spiral cutterhead makes extremely tiny wood dust that can help dust collection’s efficiency.
