Spiral cutterheads revolutionise your woodwork! Offering silent cutting as well as less chatter and tear-out in curly or highly figured wood, these cutterheads save hours of cleanup work after dressing timber.This machine's 74 four-sided cutter knives (which can be turned to offer a new cutting edge in seconds) are made of fine grain tungsten carbide and are held in place by a Torx style screw. Knives of this type last three to five times longer than good quality HSS knives. Multiply this by four cutting edges and you achieve 12 to 20 times the normal blade life of a HSS blade set.

Easily turned and seated, they present a fully sharpened and indexed cutting edge. No complex blade setting or jigs are required - you simply replace the blade when all four edges have been used. This style of cutterhead also reduces the size of shavings when cutting, increasing the effectiveness of your dust collection setup. The size of the knife and the spiral cutting action also reduce the amount of horsepower needed to drive the machine, translating into more effective power transmission on each cut revolution.

In summary, the advantages of this machine include:

• smoother cuts
• less tearout
• less vibration
• less machine wear
• less noise
• lower horsepower requirement (more cutting power)
• long life fine grain carbide
• fully indexed cutters
• better chip ejection
• rapid cutter change
• dynamically balanced head
• four rotatable cutting edges
