CED: CED is abbreviated for cutting edge diameter or the width of the cut the tool should make through the work piece. CED has a tolerance in thousandths of an inch or .xxx decimal places.
CEL: CEL is abbreviated for cutting edge length and is the maximum thickness of the material it can cut. CEL has a tolerance in hundredths of an inch or .xx decimal places.
SHK: SHK is abbreviated for shank diameter and is the nominal size of the shank which should match the collet size of the spindle the tool will be used in. SHK has tolerance in the ten-thousandths of an inch or .xxxx decimal places.
OAL: OAL is abbreviated for overall length and is the total nominal length of the tool from end to end. OAL has a tolerance in hundredths of an inch or .xx decimal places.
Tool Material: We use the finest carbide and steels in our cutting tools to ensure you get the most productivity out of your OC tools.
HSS: High Speed Steel, typical applications in Non-Abrasive Plastic, Solid Wood & Aluminum where keen edges perform best. High Speed Steel tools perform well in hand routing applications where a tough core is necessary to prevent tool breakage.
Carbide Tipped: Used for a variety of applications in composite woods, hardwoods, abrasive plastics and composites plastics to hard aluminum. Limited by geometry in some applications due to the brazed nature of the tool. Carbide Tipped tools work well in hand routing applications due to the tough HSS core and hard carbide cutting edges.
Solid Carbide: Typically used for widest variety of applications including man-made board, solid wood, abrasive plastics, and some aluminum's. Solid Carbide does not deflect allowing the tool to be fed at higher feedrates than PCD or straight insert cutters decreasing cycle times. s typically. Solid tools also have major edge keenness advantage thought only possible in HSS until a few years ago.
Chipload: Chipload is simply defined as the thickness of a chip which is formed during the machining of a material. Chipload is critical because if the chip is the proper size, the chip will carry away the heat promoting long tool life. If the chip is too small, the heat is transferred to the cutting tool causing prematurely dulling. Too high of a chipload will cause an unsatisfactory edge finish, or part movement.
