upcut-spiral-router-bit-key Up-cut Bits provide faster cutting Upcut Spiral Router Bit Example while they pull chips up and out of the work or towards the router. They are excellent bits to use when cutting material in a router table since they tend to hold the work piece to the table itself. Ideal for mortise and tenons, grooving, slotting or routing deep blind holes. Down-cut Bits cut slower and push chips away from the router to eliminate top surface splintering. Use for pattern cutting or when going completely through the board as it allows clear vision of the cutting line. Ideal for fine finish work such as veneers, laminates, inlays and repairs b   I have a 1/4″ upcut and i use that bit for almost everthing i love it. Reply. Dean (Onboard) November 30, pm. Главная.

Upcut spiral tools are the most popular type of spiral fluted tool. Use these for grooving or slotting, for upward chip evacuation and best finish on the bottom side of the part. These bits allow for rapid cuts since the tool clears the chips away from the material. While ideal for cutting thicker materials, this type of tool is not recommended for thinner or softer materials.  What is a downcut router bit? Downcut spiral tools are best used for thinner materials which will be pushed down into the machine bed rather than being lifted with an upcut spiral. This can be particularly useful when using vacuum hold down where maintaining the seal between the material and sacrificial bed is crucial.

Search NewWoodworker. While both of these Infinity bits are very effective, knowing when to use an up cut left or a down cut right can make a substantial difference in your project. Click image to enlarge Up Cut vs. The number of email questions on this subject instigated this story. Though the flutes run in opposite directions, telling an up cut from a down cut bit can be difficult if you cannot imagine their rotation in the router.

Though a router always turns in the same direction, from the operators perspective, that rotation appears to reverse upcut spiral router bit key on if upcut spiral router bit key router is bit down in the common hand-held mode or bit up, as when mounted in a router table. With the bit down, the rotation is clockwise.

That means the side of the bit farthest from the operator is turning left to right, the near side right to left. This is very important for feed direction, as we always want the cutting edges turning against the feed direction, not with it. When the router is oriented with the bit up, as when mounted in a router table, the side of the bit closest to the operator is turning left to right and the back side right to left.

Upcut spiral router bit key the wood is fed against the rotation of the cutting edges, we almost always work against the front side of the bit. If the wood is fed into a router bit on the wrong side, the feed direction matches the bits rotation, making a dangerous kick out all but certain. Feeding the wood with rather than against bit rotation allows the cutting edges to become highly efficient feed dogs that grab the wood, accelerate it and shoot it off the table at dangerous speeds.

Up cut bits are very efficient at evacuating chips from the hole or slot it is cutting. Deep holes or grooves still have to be cut using multiple light cuts, but the upward direction of the flutes while rotating prevent the debris from building up in the hole and binding or even breaking the bit.

The problem with up cut bits is that the same action of the flutes that brings the chips up can also lift or fray the wood fibers around the edges of the cut. While this damage is usually minor, especially with good quality bits, it can be noticeable if those edges will be visible when the project is assembled. Up cut bits are frequently used for cutting mortises because of their depth. Since the edges of a mortise are eventually hidden by the shoulders of the tenon that will upcut spiral router bit key fit to it, this chipping or fraying will be hidden after assembly and have no impact on the finished project.

The downward slicing action of a down cut bit leaves a very clean, crisp edge around the hole or groove it cuts.

While chips still are evacuated from the hole, a down cut bit is far less efficient in this respect than is an up cut design. This chip ejection deficiency of down cut bits is minimized by the relatively shallow cuts they most commonly are used to make.

Down cut spiral bits are a good choice for cutting dados or shallow grooves, especially when the edges will be visible when the project is assembled. Down cut bits require a slightly slower feed rate. This reduced pace allows the bit a little more time to throw chips out and for them to be re cut into smaller pieces that eventually are thrown from the hole or slot. Making shallow cuts to achieve the full depth needed is always important, but especially so with a down cut bit.

The combination of a deep cut and a build up of chips can cause the bit to over heat and even break. For most woodworkers, the down cut type of spiral bit is most useful, particularly for those using a router to cut dados, rabbets and visible slots. Some woodworkers like cutting mortises with a router, table mounted or hand-held. For them, the up cut bit will be most efficient. The ideal situation is to have both types of spiral bits in the drawer, in the size or sizes you most often use.

The quest for more tools certainly does not end with spiral router bits.

The down cut bit left leaves very clean edges while the up cut version right is far better at evacuating chips but that action can fray the edges of the cut to some degree. This up cut bit is great for deep mortises because of how well it evacuates the chips.

The minor Upcut Spiral Bit Keys fraying of the edges is of little concern because they will be hidden by the tenon shoulders when the project is assembled. This closer look at the grooves cut by the down upcut spiral router bit key left and up cut right shows the marked difference in the edges they produce.
