Milled-to-pattern bits can be designed to fit most standard makes of cutterheads. This means your pattern will provide constant, dependable production. Send us a drawing or sample of your pattern. Milled-to-pattern bits are recommended where long runs or frequent runs of the same moulding or pattern are made.

The term "milled-to-pattern" bits is used because of the way the bits were originally manufactured. However, with the coming of modern technology, we now do 90-95% of our milled-to-pattern bits on our Wire E.D.M. computer-controlled machines. Our engineers utilize CAD-CAM to develop the proper information for the computer program. If bits are reordered by the symbol stamped on the bits, the customer will receive the identical bit. Wood patterns are cut with the bits, and profiles are checked on our comparator against pattern drawings. All bits are balanced.

Milled-to-pattern bits are easy to maintain. When they become dull, it is a simple matter to face-sharpen them by taking off only a few thousands. (This is true with a proper maintenance schedule.) When face-sharpening, it is important to follow the same angle that is milled on the face. If this angle is changed, the bit will not cut the correct pattern.

When bits are assembled in a head, they must be set to the head angle (see maintenance sheet). When bits with corrugations are sharpened back 1/16 of an inch, they should be reset to the head angle. "L"-type bits must be ground to adjust for proper cutting angle. The bevel that is milled on the face of the bit determines the cutting angle. Bits are designed to give the proper cutting angle when cutting a specific kind of wood. Bits will have more than one dovetail for wide patterns. Bits are usually made from high-grade tool steels, including M-2, carbide-tipped and OPTI.

Common MTP Applications

• Multiple dowel profiles
• Louver slats
