I have spent a life time working with wood now retired and still working with wood finding new methods of using the World's most versatile Woodworking tool The Router

Cutters have been selected from a number of classification, illustrated in the Carb-I-Tool catalogue.

Straight Cutters: Straight cutters can be purchased in a great variety of sizes, from 1.6mm single flute (solid carbide and high speed steel) to 50.8mm diameter two flute (carbide tipped)
These cutters can be divided into a number of other categories, end cutting, rip or slotter, slot morticing, lock mortice, hinge mortice, staggered tip bits, spiral flute cutting (down or up cut spiral), fibreglass bits (to rout special materials)

With the aid of jigs and templates these cutters can be utilized to produce a greater range of projects

Trimming cutters: Standard cutter for flush trimming laminate and working with templates. Special cutters are designed for overhang trimming, combined flush and bevel trimming, inverted flush trimming, bevel trimming in a variety of angles.

Slotting Cutters: The most popular ‘slotting cutter’ purchased is used to insert biscuits. Others are available for inserting a range of slots from 1.2mm to 8mm thick. These are usually available as a slotted cutter assembly, then purchasing the slotted cutter to change the width of cut required.

‘Biscuit Cutter’: Inserting biscuits with the router: This cutter should be used with great care. (The cutter is set the required depth and is therefore always projecting below the base.) It is more convenient to use the slot cutter in the router table such as the ‘Triton’ Router table, where a special fence can be purchased if required to control the material to be cut.

Groove forming Cutters:
The groove forming cutters are available for inserting dovetails, routing drawer pulls, routing slots and hook slots for picture hanging.

Edge and face forming Cutters: A variety of face forming cutters, are available for inserting decorative patterns to the face of board and are purchased in a wide range of profiles. Special cutters can be made to any size and detail to suit the particular project you may be working on at the time.

Cutters without bearing (face / edge cutters) are mainly used in the ‘Below Bench’ position or controlled with the aid of template guides and jigs. These cutters can also be used with the aid of the side fence when adding edge treatment. The majority of these cutter profiles can also be supplied with bearings.

Edge forming Cutters: Edge forming cutters are designed to form a decorative edge to the material and are available in a wide range of profiles. The most popular edge forming cutters used are the rebate, chamfering, rounding over, cove, beading or ogee. Like most cutters, they are available in a range of sizes to suit the material in use. Consult the catalogue to select the cutter of your choice for the project you are preparing.

Rebate Cutter:
Is a special edge forming cutter to rebate the edge of material to insert plywood or MDF backs to cupboards etc. Special cutters are available to give a variety of rebates simply by changing the bearing.

Chamfering Cutters:A popular method of removing sharp edges and give a professional finish. These cutters are available in a variety of angles.

Jointing Cutters: Special jointing cutters are available for producing wide boards, finger jointing, tongue and groove, drawer construction, mitre lock jointing etc.

Jointing cutters are used to prepare wide boards from narrow strips and again should be used with great care and only when placed in the below bench position and not in the plunge mode.

Panel Door Cutters: These cutters are usually purchased as a ‘Matched Set’ or as a stile and rail assembly. It is important that these cutters are purchased as a set as they have been designed to work together

Raised Panel Cutters: (Horizontal) Suitable for inserting a raised panel in a door. The raised panel cutters are available with or without bearing. The cutter illustrated should only be used in the below bench router with a variable speed ½” router.

Raised Panel Cutters: (Vertical)The vertical cutter is not suitable for producing ‘Arched’ door panels and again should only be used in the router table.

Combination cutters: Combination cutters are a single cutter designed to give a variety of edge treatment to table top etc.
Note; This cutter should be used mainly in the below bench position and is limited to routing straight edges with the aid of a fence, except when using the section close to the bearing.

Special cutters: (Carving with the router) Special cutters have been designed to rout various patterns on the face of the material. This cutter should only be used with the special templates that are prepared to produce the various patterns.

Safety tips and helpful hints:
· Have your cutters sharpened by a professional service agent.
· Purchase 12.7mm (1/2”) diameter cutters wherever possible for more stability and less chatter.
· Store you cutters in a special box to keep the edges fro touching and chipping.
· Replace any worn collets, and ensure the collet is kept clean.
· Clean bearings regularly with a solvent and submerge them in thin lubricating oil.
· Insert the shank of the cutter into the chuck at least 20mm, to leave 5-10mm of ‘white metal’.
· The larger cutters such as the panel door cutters should only be used in the ‘Below bench’ position, or overhead router machines.
· When using the larger bits care should be taken to ensure that the speeds and feed rate are suitable for the diameter of the cutter in use. Seek advice from your cutter supplier.

Catalogues of cutters are available from a number of sources. Selecting a suitable cutter for a specific job can be made easier if details of the cutter sizes are shown clearly with drawings and dimensions.(1)
