This file guide will enable you to precision-file both sides of the blade dead-even, using files or your grinder. The benefits are blade bevels starting perfectly even, and stick tang shoulders being dead square and even for perfect bolster fit.

Cutting Material: Up-cut spiral router bits are by far the more versatile router bits than down-cut spiral bits. They are commonly used for making dados, mortise, tenons, and shallow grooves in bottom-veneered boards without tearing them out. Down-cut spiral router bits have a smooth cutting action, remove debris efficiently, and create clean edges on materials such as inlay, plywood, or laminated material. They are also suitable for carving and engraving designs and use in CNC applications. Compression spiral router bits made from robust solid carbide are typically super sharp and durable. It is perfect for cutting materials like double-sided veneers, softwood, hardwood, MDF, laminates, and composite materials as compression spiral router bits cut more effectively throughout and leave a cleaner cut surface on both the top and bottom of the material.

Chip Removal: The way the flute goes determines in which direction the chips are pulled. Up-cut spiral router bits evacuate chips more efficiently and allow faster feed rates than down-cut spiral router bits. Down-cut spiral router bits will drive wood chips into the cut and buildup, and require slower feed rates. Compression spiral router bits provide better chip evacuation, smoother and faster cutting, and cleaner finish.

The Carbide File Guide is solid stainless steel, and will not rust when dunked in water during grinding as you keep the blade cool. Metal dust will not stick to this non-magnetic steel.

In CNC router industrial applications, up-cut, down-cut, and compression spiral router bits are the usual cutting tools, and they come in different flute directions. A spiral router bit is generally used for plunge routing. Spiral router bits have angled cutting edges, so they slice through wood rather than chop it. As a result, they are superior at minimizing heat buildup, improving chip evacuation, and leaving a cleaner cut behind. In the field of woodworking, the selection of the optimal up-cut, down-cut, and compression spiral router bits stands as one of the many perplexing matters for many individuals. That’s why this blog will pick these spiral router bits to guarantee that you always obtain the most suitable finish.

A down-cut spiral router bit is the opposite of the up-cut. Down-cut spiral router bits are used for downward cutting in woodworking or materials that are prone to tear out or splinter like plywood, or veneers. A down-cut spiral bit will minimize the chips on the uppermost surface of the work. It’s beneficial for producing a clean cut on top of your wood while producing some tear out at the bottom of your cut. This router bit is therefore a great choice if you want to have neat and clean pockets in your project or if the good side of your project is facing upwards. When using a down spiral bit, the chips would be pushed into the cut and buildup, which would considerably produce more heat, cause burning, and reduce the lifespan of the router bit. When it is machined in a router table, it’s crucial to feed slowly to ensure safety as you would be struggling against gravity.

The idea itself was good, I just thought we could come up with a better version. After a lot of work and prototyping, we came up with the Nordic Edge file guide.

The face is protected by two carbide strips, which only diamond or other exceptionally hard tools will scratch. These are 78 HRC and very hard but: ceramic belts can and will damage carbide. This tool is for use with hand tools, or normal aluminum oxide belts if using a grinder. The carbides are 3.9mm thick and can be replaced if required.

A compression spiral router bit is a combination of an up-cut and down-cut spiral router bit. It splits the bit in half down the center, with an upward spiral first and a downward spiral following. The up-cut edge is on the tip of the spiral bit and a down-cut edge is close to the shank. This allows the bit to push the chips toward the center of the bit rather than outwards, and chips are thrown down by the top part of the bit while the bottom part is scooping them up. Accordingly, this gives you the best of both worlds, and your cutting material will retain a very nice and neat edge on the bottom and top edges, as well as producing a perfect trimming finish.

When considering the options of up-cut, down-cut, and compression spiral router bits, choosing the right router bit for your woodworking project is pivotal to achieving precision and quality in your cuts. Thus, it depends on how you want the final result to look. It is recommended to use an up-cut bit when cutting mortises because it effectively removes chips from the hole. Although a sharp up-cut spiral router bit works just as well, a down-cut spiral router bit is more frequently employed for shallow inlay work. Compression spiral bits stand out as a superior choice for many applications as they integrate the combined advantages of up-cut and down-cut spiral bits. By carefully considering the requirements of your specific woodworking task, you can determine which type of bit to use in each situation. Contact us for guidance if you’re not sure which option will be ideal for your project especially when working with challenging materials or intricate applications. Findbuytool offers a diverse range of high-quality up-cut, down-cut, and compression spiral router bits, providing you with the perfect tools you need to achieve exceptional results. We combine micro-grain carbide, a full CNC production line, a top-quality steel body, and self-invented product quality inspection procedures to produce industrial-grade CNC router bits for our customers. We hope this guide will improve the outcome of your future projects.

Up-cut, down-cut, and compression spiral router bits are the common spiral router bits, they differ greatly from one another in some aspects.

This pro tool will give you nothing but consistent, repeatable results. Easily adjust & lock in your angle, and knock out perfectly matching bevels and plunge lines.

An up-cut spiral router bit is recommended for most case usage. It’s great for plunging as it’s evacuating the chips upwards so you can do a straight plunge. For a woodworker who wants to make a dado or groove in straight-grain hardwood like walnut and maple, an up-cut spiral router bit would work better since it would allow for much greater chip evacuation and a cooler cut, which allows for faster cutting. When it is machined in a router table, an up-cut spiral router bit will pull the chips out of the cut. Since up-cut spiral router bits are designed to pull projects away from the work table, you should have enough hold-down clamps when working with smaller pieces.

This bevel jig is designed for use with a file guide, so there is no stopper bolt supporting the blade spine. If you're using this without a file guide, clamp the blade securely to the bevel jig with 2 G-clamps or similar. It is 150mm wide with two slots for the Carbide Faced File Guide (not included).

The carbide strips are recessed slightly down into the stainless steel for added protection. This way the strips will not be knocked off, or be under pressure when clamping a blade in the file guide. This also ensures there is less pressure on the carbide strip when clamping in a blade as they back onto a shoulder of steel.

Cutting Action: The primary distinction between an up-cut and a down-cut spiral router bit is their edges are cut in the opposite direction of rotation. If the flute rises to the right when reading the flutes from left to right, you have an up-cut, it sends all the chips upwards, so it leaves you a clean bottom side. On the contrary, A down-cut is present if the flutes descend to the right. A compression spiral router bit has an up-cut which is approximately the first one-quarter of the cutting length of the router bit, while the remaining of it is a down-cut.

This is the first file guide in the world with screw-on carbides that cannot come off. We made it using stainless steel that will not rust, as well as being non-magnetic so steel dust won't stick to it as you grind. We think this is a good version of a file guide and you can now grind matching plunge lines, as well as get those really crisp blade to guard fit-ups with less hassle.

Up-cut spiral router bits are an efficient tool for moving chips up and away from the slot being cut with their upward spiral cuts. Because of this upward cutting direction, it sufficiently minimizes chips on the lowermost surface and leaves a smooth and nice finish on the bottom surface of the material but a rough top edge. It’s therefore the ideal option if you want to ensure that the good side of your project is facing downwards.
